No wind-up, mate, it's all market forces.
People on another thread (inc.WWW) have suggested that some poor sods will be instructing for little more than nine tenths of F.A., or pay to do it! Sorry, but there's always someone desparate to do it.
I don't imagine they have high margins and agree that plenty more schools will disappear but there is going to be fierce competition between the survivors for those who wish to train.
If you decide to train abroad, the price of late booking charter flights is peanuts (saw many UK-Orlando £99 returns on one site !)
Cannot comment on OZ but the price of Avgas is always ludicrous (and probably rigged by suppliers) everywhere. But oil price has come down significantly in recent weeks and petrol prices have already been cut in UK. Cheaper Avgas will surely follow.
Remember, also, that 'CAA' PPL course prices went up very quickly and by about 50%- for some good reasons (JAA requirements, fuel costs, shortage of qualified staff)-when there was plenty of training business for the big schools. That's all just changed, so the cuts are coming.
The point is- good time to do JAA PPL.
