Toughen up, get a PPL.
To be a true pilot you must fly across Australia. Try and time it for the Avalon Airshow. You'll learn a ridiculous amount of navigation, runway selection, fuel planning and contingency skills that you will never get from a jolly around the metro area.
Better yet, do a NVFR after that too - the circuits at night, in summer, are a lot of fun, especially if you can pop the canopy (according to the POH) on your aircraft.
Doing those night circuits with minimal or constant wind down the runway - it really hones all the skills especially if you do it not long after the PPL and the cross-wind landings night-landings away-from-base are exhilarating. Black hole landings and the instrument reversion really were mentally-satisfying to me, event when the lighting went out at 100 feet AGL. Early computer gaming experience perhaps helped here? PS - Yes, that was a go-around to reactivate PAL, instructor aboard, with a crappy PAL that couldn't be reset, and lighting shutdown was known to be imminent.
