Future Australian Aircraft Acquisitions

I have a question, since there is sopposidely a growing threat of Indonesian and Malaysian Flankers, which outclasses the F-18 of RAAF.

1)Will Australia wait for F-35 which wouldn’t be be sopposidely available till 2015 or later to Australia or will they purchase something else like Typhoon or Rafale?
2)Are they planning to replace both of their F-18s and F-111s with a single multirole type?
