Australia will be starting a massive shipbuilding program in Q4/35. It will include 3 Heavy Cruisers and 2 Aircraft Carriers, plus a number of lighter ships.
First up is the Bismark class Raider Hunter. They are designed for long range independant operations and are capable of tackling all raiders from CA size down. They will look very similar to the Sydney class Large Cruisers:
