Of course the Australians didn't start their own program. They are on the JSF track, which is the perfect replacement for F111's, F18s and everything required for the next 30 yrs..
There are more initiatives though. Turkey is looking with Italy at options (TFX) and possibly Saab. India has set apart billions for their AMCA, the Koreans are reconsidering their KF-X and talking to Turkey (?)
I'm not sure the Germans/ French are sitting on their hands either. Even the frigg'n Iranians are developping a light stealth fighter. The Brazilians will come out if they can make money, Russia and China are steadily progressing. The Japanese are starting to loose their patience begging for F22s.
I'm just not sure the JSF is the answer to all requirements.
Sooner then we think/ hope a J-31 might land on a carrier & we can all be surprised again.
