And since then, the Americans are increasing their presence in Australia, which eliminates any realistic Fortress Australia threats which was part of the argument for a 100 aircraft JSF fleet.
Looks to me as though there will be emerging arguments within the next few years for an actual reduction in RAAF fighter squadrons.
On the contrary...the US aren't "increasing their presence in Australia", just using our bases and ranges for 4-6 months a year for training as they get squeezed out of Japan. I believe with the US's pivot towards the Pacific, the onus is on us even more to step up and offer our fair share.
