On Holiday recently I hired a new 172 out of Van Nuys and was $160 odd per hour including tax. So $235 Aussie. A older 70s model was $30 cheaper.
I could also hire a Seminole out for the same price of a 172 hired out here in Melbourne, currency and tax converted!
Briefing and/or Instructor fee per hour was $80-$100us around most places.
Fuel was $1.80us litre. Landing fees even at major places were a few bucks.
Landing a 172 at big airports on a very tight parallel with a dozen odd 737s waiting and departing only set me back a few dollars in landing fees. What we do here is ban GA traffic between say 10-3pm (CNS cough..), decomission small runways to piss of the GA traffic (umm CNS again), charge monstrous landing fees, and to top it off give us 48hrs notice before you come. The latest and greatest is charging the Aussie GA battler for an approach.
