My suggestion is to get to know an owner of an aircraft and hire directly off them.
All flying schools etc make at least $30 per hour on top of running costs for administration.
I personally prefer not to pay this as aircraft hire is becoming more expensive of late due increased fuel, fees and maintenance and the extra $30 dollars or so per hour is better off in my pocket.
However, Redcliffe is a good place to start to look for an owner who is looking for competant pilots to private hire his or her aircraft.
Be sure to take the appropriate steps to be added to the insurance policy for that aircraft which you intend to fly.
