Yes it is sort of simple. But you need to be aware of it, remember it, fill it in time (some processing can take 2 weeks), carry reference number.

I'm somewhat organised, but didn't really knew I need for for AU. Filled while checking in, but got it 8 minutes after gates closed.

Edit: kinda feel should be integrated with flight booking. The amount of bureaucracy, esp. during covid era, travelling across many countries, with a big party - it's maddening.
