Hi Liberty,
I'm not a very good example to gauge time frame as ASA sent me the wrong online tests to do originally so, I had to do the online tests twice!
From the time I did the online tests it was about 1 week, then booked my phone interview, then a week after that I was invited to the testing day here in Sydney.
That brings us up to now!
Sorry, this probably isn't much help but, I have found that if you phone into the recruitment centre, everyone there is really helpful so you should get some answers.
Cheers.
