The Aussie air assets are essentially the Same as the British barring some changes in MARs (model assigned rules) to make them Aussie and not British. As for allies you couldn't go wrong with Brits, but the Indian Raj wouldn't be bad either. The Aussies and the Americans also pair surprisingly well together. The long range of the FSA, with cheap carriers, is brutal when combined with the heavy weapons and boarding actions of the Australians. It's a fun combination.
