Hey alyssa,
I applied for V Australia in June this year but never heard back regarding my application. So to answer your question, there was a separate job listing for V Australia cabin crew. Intake for international cabin crew is quite small however because there are no new aircraft coming on board as yet. So I applied for a domestic cabin crew position in late August and got the job this week.
If you're really keen on being international cabin crew, my advice would be to apply for the current domestic openings now and try for an internal transfer further down the track. You'll have your foot in the door with the company, so your chances of getting it will be much higher that way.
