I can confirm that there has already been recruitment for Mel Base International as there is a group currently going through now. Many of them however have been on hold for a couple of years so I don't know if interviews were necessarily held for new recruits recently. There has also been recruitment for Sydney International and Mel and Perth Domestic.
Just keep your an eye out on your emails. I don't know what the situation is with further recruitment but I do agree that with so many more aircraft coming online, more crew will be required.
