You seem to have the comedy market cornered, so I wouldn't stand much of a chance.
China has two carriers that can reliably get to Australia and do any air operations you please and it's going to have many more soon. China's SSNs are now at the cutting edge (and if they weren't, they sure are now with Russian assistance).
Which two carriers would that be?
Neither of the current 2 Chinese aircraft carriers have demonstrated being able to sail anymore than 500 miles from the Chinese coast as of yet.
Say they do, then they can only carry a maximum of 60 aircraft in total and so around 50 J-15s. How long will they be able to maintain flight ops, so far from home?
Australia airforce currently has 24 F-18E/F, 45 F-35A and 6 E7A AWACS.
If those carriers and their escorts somehow get into position near Australia they will almost certainly be sunk by the Austrlians.
Wait till you get those 2 larger carriers before making threats as currently the PLAN stands no chance of threatening Australia.
