POM,
As a former RAAFie and QFI I fully concur with Capn Bloggs sentiments. Whether you flew a hornet or Bou in the RAAF makes no real difference in your suitablilty for airline selection. What does count is your motivation, persistence and personality. Different airlines will have different views wrt military guys but they are just generalisations. Like Cap said, there are bad candidates from both sides of the fence.
Start applying now and best of luck.
