I did the modular route and completed my PPL all the way up to CPL and IR with ACS at Perth. I commuted everyday from the central belt although there is accommodation at the airfield. You can complete everything there apart from the last stage the MCC course which is around 20 hours in a sim. Integrated wise I know many people who have done that route at AST. All say the same , that the flying side is great but the groundschool is not as great at rival integrated schools.
