G'day AllInGoodTime,
It has been a few years since I did the ATPLs but my guess would be that they haven't changed that much. If the Planning exam still uses the 727 book then I'd say its fairly similar, altho I vaguely recall hearing something about switching to 767. Met, HF, Systems etc should be much of a muchness.
I'd suggest you get Trevor Thom's ALAW book, lots and lots of Q's that will have you knowing the Docs backwards, and its reasonably cheap.
Good luck.
