Just got back from a 3 day weekend in Adelaide myself- OK to fly- some airlines like you to have a medical certificate but i flew Quantas and they were ok with it and i didnt need a med certificate...

Only thing was the pressure up there made me have bad cramps but i was told it was normal. also felt quite queezy when we landed but other then that i was fine...

Your not as far as i was ao i'd say you should have no probs just relax and enjoy the flight... good luck
