I do know that at the moment all Qantas wannabes are in a holding pool.
My friend worked for them for 3 years and absolutely loved it, she left for the BA 11 month contract cause she got bored of the repetitive destinations eg SIN, HKG and BKK. She regrets making that move now, as she is hoping to go back but there isnt any positions.
I know they used to have really good fun!! downroute.
Also another thing Qantas UK is a company in its own right and takes EU crew on not Aussie passport holders, I have dual UK and Oz passports, but to apply for Qantas in Oz will have to go through an interview completely different from the Uk company.
Hope that helps - I do know that they are giving part time positions internally.
