Australia Twilight War & After...

[Jason Weiser]

In terms of any Australian target list/ORBAT. I would say I would be more than willing to defer to Leg and Targan on that one. It's your country guys, and honestly, you know it better than anyone.

I would say considering the nature of the exchange, the Soviets wouldn't have much incentive to hit a lot of targets in Australia/New Zealand.

Let's go down the list of potential reasons and target base in Australia.

Nuclear weapons? None that I know of, unless you guys have something to tell us. Now there might be some SAC recovery bases but that's a bit of a stretch....though Chico might know something there. Also, a US or British SSBN might put into an Aussie port? Again, those are time sensitive targets, so methinks those would be dealt with by a Soviet SSN with SS-N-21 SLCM.

C3 targets? I am sure Australia has a few, but how hardened are they and are they joint commands with PACCOM? Or are they national, and if so, are they supporting Australian forces cooperating with the Allies? If so, they're going to be hit, if not, then why waste the warhead?

Oil refining? I could see that on the principle of resource denial, but how big are they and how much do they produce? Chico and I worked on a revised target list for a project we will release later. Suffice to say, we decided to hit Oil Refineries of 100,000bpd production or greater. It conformed CLOSELY to the canon list, but there were some differences, heck, if anything, I think MORE targets wound up on the list.

Here's the list for Australia and New Zealand from Wiki

Australia
New South Wales
Kurnell Refinery, (Caltex), 124,500 bbl/d (19,790 m3/d),[17] Botany Bay
Clyde Refinery, (Royal Dutch Shell), 100,000 bbl/d (16,000 m3/d), Clyde
Victoria
Geelong Refinery, (Royal Dutch Shell), 130,000 bbl/d (21,000 m3/d), Geelong
Altona Refinery, (ExxonMobil), about 75,000 bbl/d (11,900 m3/d), Altona North (refinery reduced from 2 trains to 1 train between 2000–2004)
Queensland
Bulwer Island Refinery, (BP), 90,000 bbl/d (14,000 m3/d), Bulwer Island
Lytton Refinery, (Caltex), 104,000 bbl/d (16,500 m3/d), Lytton
South Australia
Port Stanvac Refinery, (ExxonMobil), 100,000 bbl/d (16,000 m3/d), Lonsdale (mothballed since 2003 - 239 ha site to be cleaned up and redeveloped for housing)
Western Australia
Kwinana Refinery, (BP), 138,000 bbl/d (21,900 m3/d), Kwinana
New Zealand
Marsden Point Oil Refinery (NZRC), 96,000 bbl/d (15,300 m3/d)

Now, what I did? Took google earth, got a lat long, then found a decent blast mapper and actually did a targeting plot. Chico then revised some of my targeting (I kinda went HULK SMASH, such as the infamous example of hitting oil refineries with 400-500kt each, when they were across the street from each other...)

That's about it..I am sure you guys can come up with other ideas...but I thought putting that out there might help.

if you need two 500 kt warheads for refineries that close you have some pretty crappy warheads

Perhaps terrain is a factor. Or perhaps the CEP is so great that two strikes are warranted.

Agreed. We can only expect so much from a small group of guys creating a game against publishing timelines before the advent of the Internet. Our Bible has limitations.

I’ve included a couple of attachments regarding how Canada fared in the Twilight: 2000. We’ve now established that both Canada and Australia fought against the Soviet Union. They are both non-nuclear middle powers allied with the US. Cut the megatonnage directed against Australia in half (compared to Canada)just for the sake of being nice to Australia, and you’ll still get a pretty serious body blow to the Land Down Under. Again, I don’t say this because I like the idea of my Australian cousins being incinerated or dying of radiation poisoning. I say this so that we don’t create separate standards for important players in WW3.

All of this said, we all have to go with what we like most. I believe I told Mo that all he had to tell me was that he didn’t want to have a nuked Australia in his campaign and I’d close my mouth on the matter. However, if one wants to present a rationale for Australia being un-nuked, then that rationale a) must defend itself and b) is available for challenge. There’s no reason for it to be personal.

[Legbreaker]

There's bound to be some indications of Indonesia's intentions beforehand, so we should be able to justify pushing the reserve call up back about 6 months. Perhaps the official explanation, at least the one given to Indonesia anyway, was that it was a response to Australia's UN obligations in Korea, or to help out in Cyprus letting the British got to war in Europe. A bit thin, but aren't most political statements?

The timeline is important here too. 3rd Brigade probably goes over to Korea first and the reserves are called up at the same time to begin training. Recruiting efforts kick into overdrive and maybe conscription sugar coated as a way of reducing unemployment, kick starting the economy or something like that.

Officially the reserves are only supposed to serve inside Australia as a defence only force, somewhat like the WWII militia were supposed to, however once Indonesia makes it's move, 1st (less 1 Armoured Regiment aka Koalas - protected species not allowed outside Australia ) and 7th Brigades are sent into action, 9th Brigade is sent to relieve 3rd in Korea who are brought back home for predeployment training and reaclimatisation for PNG and to give commanders an airborne option (3 Para battalion).

8th, 11th and 13th Brigades are deployed to the north of the country while 4th and 5th Brigades (plus the Koalas) are kept as "strategic reserve" but sent into disaster relief duties when the nukes hit.

3rd Brigade may not make it to PNG but could be redirected as a "fire brigade" at home.

The list of refineries from Wiki is a very decent starting point and only needs fairly minimal expansion to completely screw Australia. Another half dozen warheads aimed at shipyards and the like and it's all over. Hitting those targets will also still take out a huge percentage of the population, even if that wasn't the intended aim.

That restriction on the Reserves only serving within Australia was watered down years ago. East Timor, Bougainville, the Solomon Islands are just a few of the places I can think of off the top of my head that Reserves have been sent to in recent decades. Heck, official ADF recruitment advertisements on TV have for many years suggested that overseas service is a potential benefit of joining the Reserves.

Very true. Over here in my corner of this Wide Brown Land the Kwinana Refinery sits right on the coast, in a strip of industrial zoned land south of the main metropolitan area. Perth and it's satellite cities and suburbs occupy a long, narrow strip of very flat sand plain, bordered to the east by a continuous low escarpment rising up where the old shoreline used to be in ancient times. The prevailing winds along this section of the West Australian coast tend to be consistently from the south-west. A single nuclear warhead detonated over the Kwinana Refinery would demolish a very significant proportion of this region's heavy industry, shipbuilding and fuel refining capabilities. Conveniently that same warhead would also severely damage or destroy the nearby HMAS Stirling, the largest naval base in this part of the world and the home port for half of Australia's submarine fleet. Then, just as a nice little additional kick in the teeth, the radioactive plume would be carried by the consistent prevailing winds right across a significant part of Perth's southern suburbs and urban-rural interface (market gardens, dairy farms, quasi-rural redneck spawning grounds etc.).

And in the event of a summer nuking, the nuke plume would also tend to get trapped in the lower atmosphere by the almost-constant temperature inversion layer held in place over Perth by the eastern escarpment. Look, in a way a modest nuking would probably do Australians some good. As it is now we're so used to surviving on a continent that seems hell-bent on trying to kill us with its horrible climates, vast deserts, limited fresh water, inedible/angry/poisonous/morphologically confusing flora and fauna and soul-crushing isolation that we've developed cultural assumptions of near-indestructibility. Radioactive fallout would finally give us an environmental factor that we couldn't just avoid, ignore, blow up or shoot.

Absolutely (see my treatment of the reserve 9th Brigade being sent to Korea). My thoughts about leaving the rest at home are that about 75% of their numbers would be new recruits and possibly conscripts (if not in name, in practise). Ensuring only volunteers went overseas may go some way towards placating the anti-conscription groups.

[Olefin]

I would make an argument that some of the targets in Australia may have been missed as well. If you look at the attacks in the US there were clearly misses and malfunctions in the attacks there.

Given the distances involved (any shot against Australia from either of the sub bastions the Soviets had in real life near the Soviet coast or from their ICBM silos), the fact that they are are targeting areas not normally targeted (I have real doubts any Australian facility was ever targeted for real during the Cold War with the exception of one or two major cities), and the performance of the missiles as seen in the timeline I would see some of their naval and oil production facilities surviving - with these being the basis for the areas of control that the Army builds on.

I.e. they go for Sydney but the shot misses and lands off in the ocean instead of the city center or the missile hits dead center in a naval ship yard and fails to detonate but still causes a lot of damage just from radioactive debris that has to be cleaned up.

Canada is a much different case as the attack on the US had to pass right overhead - so obviously that country has a much higher possibility of successful missile impacts. Its a much easier shooting solution than Australia and also one that they can get better data about if they did miss - i.e. a recon plane can pretty quickly tell them they missed and fire again where Australia, if their satellite network is down, could take quite some time before they know they missed the target.

Why would they not be targeted during the cold war? It's not like they had a shortage of warheads. My guess is the US probably targeted us as well, just for the practise and just in case a decade down the track we switched sides for some reason - not like the US were short of missiles either, and targeting doesn't automatically mean launching.

Even a near miss though would inflict terrifying casualties on the population. Australian cities aren't as condensed as those elsewhere in the world. You can drive along a highway for an hour in some cases and still be in the same city. Given the range the Soviets would have to deal with, it's likely they'd have used ICBMs too with their correspondingly larger potential payload and therefore theoretically larger blast radius.

Outside of Europe and North America, Australia is one of the most developed countries on the planet (technologically and economically). It simply makes no sense for the Soviets not to attack.

As for recon of the damage, isn't that what satellites are for? No need to fly a plane all this way just to take a few photos.

They'd learn plenty from terrestrial sigint. The Australian media would be screaming its lungs out on every functioning bandwidth in the aftermath of a nuclear strike. And in the cases of isolated but highly developed places such as Perth, the sudden total lack of available sources of sigint would tell the Soviets plenty. A single low altitude airburst over the industrial parks south of Perth would clear the local communication EM bands instantly and utterly, and the EMP would fry electronics and most electrics over a wide area. No more ULF from the submarine HQ, no more commercial and military ship-to-shore transmissions, no more emergency services dedicated bands, or TV or AM/FM radio broadcasts. Just long lines of shell shocked survivors streaming north and east on foot or in the few drivable vehicles in search of accessible water supplies, because the pumping stations would be dead, the Swan River is estuarine and the ground water is undrinkable.

Darn, how depressing. Why the hell do I live here?

And not just during the Cold War, either.

In fact, that subject came up recently. As a card-carrying member of the NRA and a former MI squint, I’m invited periodically to provide feedback on our nuclear target list. (That NRA lobby really knows how to influence people and policy!) There is now a target identifier with the label “Legbreaker’s house”. When asked why I wanted to invest a 20Mt warhead on a ground burst in the Australian boonies, I replied,

“If we’re making any plans at all to hit Australia, this guy has to go. He’s not the sort we want to leave alive. I say we nuke the site into orbit. It’s the only way to be sure.”

Web, you weren't supposed to tell him that! Aw darn it, now the birthday surprise is all gone. Hell, we even taught the nuke to knock and say "Avon calling".

Ever heard of Pine Gap? I'd be shocked if it wasn't on the Soviet target list.

[Jason Weiser]

As would I James. Nurrungar probably not, it's an early warning facility associated with the DSP, which is not something the Soviets wanna screw with considering the nature of the T2K exchange.

Yeah and that's just one of the places that were on the target list.

There was also the Harold Holt US Navy submarine communications base near Exmouth in Western Australia that provided naval communications as far afield as the eastern part of the Indian Ocean and the western part of the Pacific Ocean.

There was also the Australian Army communications base in Melbourne that provided direct comms from Australia to Canada, the UK and the USA. One of it's secondary functions was to provide alternate comms for any of those three northern hemisphere nations to any of the other ones should their normal comms go down.

There were some others that aren't common knowledge but in general, there were at least five potential targets for Soviet nukes and two of them were in major Australian cities.

Edit:
A quote from Current Affairs Bulletin, Vol. 59, No. 7, December 1982, pp. 14-26 by Brian Martin titled "The global health effects of nuclear war"
In the main, the section quoted below was lifted from the following source:-

Desmond Ball, 'Target Australia? No 1: Pinpointing the US Installations', Pacific Defence Reporter, Vol. 8, No. 3, September 1981, pp.25-33; D. W. Posener, 'Target Australia? No 3: Planning for Radiological Defence', ibid., pp.42-52; Desmond Ball, 'Limiting Damage from Nuclear Attack', in Desmond Ball and J. O. Langtry (editors), Civil Defence and Australia's Security, Australian National University, Canberra, 1982.

"The prime targets in Australia are the United States military bases at Pine Gap, Nurrungar and North West Cape. Attacks on these bases would kill perhaps a few thousand people. There is a smaller chance of attacks on Cockburn Sound and on Darwin RAAF base, which are hosts for United States strategic nuclear ships, submarines and aircraft. Nuclear bombing of these two facilities, which are close to the population centres of Perth and Darwin respectively, could kill up to one hundred thousand people, depending on the wind direction at the time. Perhaps least likely, but certainly most devastating, would be nuclear attacks on major population centres. For example, the ports of major Australian cities could well be bombed if United States warships carrying strategic nuclear weapons were in harbour. Major population centres might also be hit as a consequence of attacks on associated military or economic facilities. Such attacks could kill from a few hundred thousand to several million people."

[RN7]

Weren't all these potential targets in Australia covered in my list?

[Webstral]

Perhaps independent confirmation was needed for some. Your list was quite good, RN7.

[Jason Weiser]

My attempt at a list...YMMV

[StainlessSteelCynic]

Not diminishing or disputing your list, trying to add weight to it by showing that like any country that was allied to the UK and US, Australia too was on the target list no matter how insignificant we might have seemed during the Cold War.

While the ANZUS treaty has been mentioned, Australia was also part of the South East Asia Treaty Organization (SEATO) until it's end in 1977. SEATO was a directly anti-communist pact developed from the Truman Doctrine.

We are still part of the Five Power Defence Arrangements (FPDA), a series of defence relationships established by a series of bilateral agreements between the United Kingdom, Australia, New Zealand, Malaysia and Singapore.

Australia, by virtue of British colonization, is intimately tied in with the UK and the US. While not part of NATO, we are definitely part of the allied nations for the UK and the US. While that may or may not rate an immediate nuking, it certainly means we were kept under observation by the Soviets especially after being actively involved in attempting to stem Communist influence in Korea, Malaya and Vietnam.

For what it's worth, I asked for three warheads of 20Mt each. There was some grumbled mention of diverting nukes from targets like land-based ICBMs, overkill, and the like... They just don't know you like we do.

[Targan]

I'd always assumed it was due to the lack of extradition treaties with the rest of Australia

[RN7]

For those of you who think that Australia survived T2K without much nuclear damage then Jason's list must be a disapointment!!

The combined population of Sydney, Melbourne, Brisbane, Perth, Adelaide, Canberra, Newcastle, Geelong and the other targets is about 13 million people even in the 1990's. It includes most of Australia's manufacturing capacity, oil refineries, major sea ports, strategic intelligence and communications facilities, airports and air and naval bases.

What survives of note?

Major cities over 100,000: Gold Coast (QLD) (probabaly damaged from strike on Brisbane), Wollongong (NSW), Sunshine Coast (QLD), Hobart (TAS), Townsville (QLD), Cairns (QLD), Toowoomba (QLD), Albury (NSW/SA), Launceston (TAS) and Ballarat (VIC). Basically NSW, Victoria, South Australia, southern Queensland and Perth gets hammered. Tasmania, northern Queensland, Western Australia and the Northern Territory outside of Perth and Darwin are the best places to be.

Oil Refineries: The Exxon-Mobil refinery at Alton (Vic) 75,000 bbl/d and the BP refinery at Bulwer Island (QLD) 90,000 bbl/d. But both probably damaged from nuclear strikes on Melbourne and Brisbane.

RAAF Bases: RAAF Curtin (WA), RAAF East Sale (VIC), RAAF Pearce (WA) (probably damaged from strike on Perth), RAAF Scherger (QLD), RAAF Tindal (NT), RAAF Townsville (QLD), RAAF Wagga Wagga (NSW) RAAF Williams (VIC) (probably damaged from strike on Melbourne) and Woomera (SA)

Naval Bases: HMAS Cairnes, HMAS Stirling (probably some damage from the strike on Perth).

[Legbreaker]

Wollongong is high priority on my list of targets due to it's coal mining and heavy industry. It may survive if the warhead hits a couple of miles off course inland (the escarpment might partially protect it), but I doubt it.

[Jason Weiser]

True, but without the oil from the now dead refineries, the coal mining and manufacturing is coming to a screeching halt. It was an argument Chico and I had, do you take out the tank plant, or the oil refinery providing fuel for the tanks and power for the plant?

I remembered that in 1944-45, as the Allied bombing campaign switched to hitting Germany's synthetic oil refineries, you had Germany making more fighters and tanks than ever...that just sat where they were, with no gas to power them....

Sure, there's two refineries left, but they are low output, probably damaged by the blasts from other attacks and there's a lot of competing priorities now for whatever gasoline is left.

Well, yes. If we go off that list with every warhead doing roughly the level of damage to it's target that it was intended to, that's it, game over for Australia as the nation is now. Pretty much permanently. I guess the people that came here after the Twilight War and founded whatever nation or nations that came to exist on this continent might still use the name Australia but anything resembling my Australia in terms of its culture, society, governmental institutions would likely be gone. The Australia described in Traveller: 2300 sounds very much like the direct descendent of the pre-Twilight War Australia so for me it couldn't have been so thoroughly cleansed by nuclear as that list suggests. I happily recognise that not everyone regards T2300 as a believable future timeline for the T2K universe but I do.

Are we going off your list or Jason's? According to Jason's list HMAS Stirling is literally carpet-nuked. Coming up with feasible Twilight War strike lists is quite a tricky process and I wouldn't expect everyone who assembles a strike list is going to have the time or patience to make themselves extensively familiar with the geography every every target. But the strikes listed for the Perth area in Jason's list are a fairly obvious case of massive overkill. Two of the three targets listed (Kwinana Refinery and HMAS Stirling) are about 7km apart and face each other unobstructed across protected, open water and between them receive six (count 'em, six!) 800kt warheads.

Just... why? Why would you pour a combined 4.8mt of nuclear destruction onto an area less than 10km across which is completely flat and not hardened against that sort of attack? One warhead would do all the damage needed, but why not say two for good measure. And lobbing three 800mt warheads all at Perth Airport? Is there a vast hidden subterranean military-industrial facility buried under there? And why would you throw three warheads at one airport but not throw even one at the biggest RAAF fighter base on this part of the continent, RAAF Pearce, which is just north of Perth?

Ok, some notes, I chose the SS-18m5 as it had a 16,000km range thus the oomph to GET to Australia. It's the longest ranged ICBM in the Soviet arsenal. It's got 10 800kt warheads. So, sadly, the overkill factor is a given.

I double teamed a lot of targets on the assumption one or more warheads might fail to fuze. It was a Soviet preoccupation. Not to mention their warheads tended to be higher yield to make up for their higher CEP.

As for Perth Airport, I wasn't sure if RAAF Pearce had such a role. I can switch that. I hit the airport as the Soviets would see it and say "Ah, B-52s could land there comrade".

To do an airfield, you want to parcel out three per runway. One warhead at either end and a third right on the middle.

Finally, in terms of overkill...it's the Soviets? When have they not been into overkill?
