How Australia is exposed to invasion.

China has always played the long game in their plans, compared to our politicians who can't plan past the next election.
This is why they have slowly been setting up their chess pieces strategically around the world.
A port here, runway there, manmade island chain over there...
What I see (and the government should see as well if they weren't so blind) is strategic military outposts.
Their little collection of ports and runways they have built up in the smaller countries around the world are actually well placed to give their army/navy/airforce valuable refueling and rallying points around the world to launch attacks wherever they deem fit.

Even the runways and "scientific research" bases they built in Antarctica allow them to strike from these jumpoff points.
Their takeover of the smaller islands to our north such as PNG, Tonga etc all allow them to cut our shipping routes in a blockade if they want to cripple us, since they know that due to the UN policies (Lima Declaration for instance) and government red and green tape has all but shut down our manufacturing industries forcing us to rely on imported goods, especially fuels.

Onboard with the concept frostbite but in a third world nation such as Australia there are a few serious problems that will prevent this from happening. 

1) Our politicians are more focussed on serving their Chinese masters over their electorate / constituents, so they will not willing arm 8 million fighting age males / females to defend against the folk that reward them so richly. 

2) At least half those of fighting age will turn their rifles on the other half due to their alternate loyalties which are driven by their ethnic and religious origins! We can thank the promoters of our multiculty utopia for this.  Only nations with a strictly genous population, culture and values can make these defence arrangements viable! 

3) The Chinese have more Intelligence Agents, Sleeper Cells and 5th Columnists active in Australia than all of our security assets combined! 

I always said the serious threat to Australia was Chinese domination, it's real and in our face right now!  That whole "Islamic Terror" thing was a circus like distraction that TPTB continue to push to this very day, Sydney stabbings last week are a classic example, witness how quickly Senior Police, Media and assorted Politifilth jumped on board with the "it's not Terrorism related but then again it could be" narrative! 

I've said this before: The US isn't giving us up to anyone as long as Pine Gap stays where it is. It's in the top 5 strategic targets slated for maximum overkill in the event of a nuclear exchange. Anything with that much Nuke aimed at it must be pretty damn vital.

But even knowing that; it's time we put away the toys. Time to get 4-6 proper nuclear subs and a dozen nuclear missiles and a balance of conventional missiles to arm them. These subs don't mess around in the shallows up north hunting piss-ant surface vessels - they loiter on patrol in the deep pacific ready to raze cities to ash.

Scrap the JSF program, conventional sub program and the air defence destroyers to pay for the conversion to nuclear capability. More long range maritime surveillance planes and satellites to keep an eye on whats happening off shore. Some s400 SAMs up north would be handy bit of kit too if the Russia will deal with us.

We are never going to have a credible conventional deterrent against anyone except NZ and PNG.

Happily, China seems to like Oz just as it is and they have little history of Expansionism. Indonesia, on the other hand ... quite expansionist. A much more likely contender for trying on an invasion - especially as all their islands start disappearing beneath a rising sea.

China won't attack us in a conventional way, they will stick with government coup style takeover, simply be ause they want our endless resource.. Coal, iron ore, bauxite, oil, oil shale, gold, uranium. Farm land..

They are about to start bringing in the new generation of new subs to replace the Collins class ones. 
But the first one won't be operational until 2030 and the rest of the fleet will be phased in over 20yrs.
It will be a diesel electric attack sub

Unfortunately I think those attack subs are a waste of our time and money. They lack unsupported endurance for wartime operations and don't launch strategic ballistic nukes.

We used to be Brit-stralia before we transitioned to Amer-stralia. I think as long as the Chinese keep expanding their interests and buying up assets here the 'invasion' will actually be an economic transition to a China-stralia. In fact, I'd wager that China already has so so many interests and investments here that if Jakarta ever tried to invade us China would step in on 'our' side of the ruckus.

Yep might sound crazy but don't forget the idiots that "Govern" us are capable of absolutely anything, especially if it's detrimental to Australian born citizens!
