Really good posts here.
I'm also in the middle of the process, and would only add one thing;
Class 1 medical cost me nearer A$700 all in, and took a while to get done, so make that a priority as soon as you arrive.
ASIC cannot be issued until you have a FCL, sooooooo send it off with your CPL license.
The CPL is good old fashioned pilotage and chart reading, so remember your days in a cub following roads....
And after all is said and done, don't forget how great a place this is, and how worthwhile it will all have been when you have a job and a visa!
