One good book I have come by (and I've seen heaps on this subject) is called Military Aptitude Tests (or similar) it's published by a company called 'AVCO'. Lots of examples similar to that of the qantas tests.
As for the phyc test. It's all good in saying 'be honest' but from experience I've found it difficult to do that. But the one bit of advice that help me get past that was that they don't read the answers to each individual question. so when you get a question like "do you like sitting still for long periods" it has an underlying meaning which, unless your a phycologist, will have no idea what they are getting at. So be honest, after all you are the right type of person... aren't you?
