PMI course
I suggest you call around a number of flying schools that deliver an Instructor rating Course. They will be delivering the PMI course and would most likely welcome you in for that component. Instructor Courses are commencing at one of Moorabbins Flying Schools every few weeks. Try Royal Vic Aero Club, Moorabbin Flying Services, Tristar, Oxford, or MFT at Moorabbin. Cheers and good luck.
