From memory the only people heading down the line of JAR theory are the Western Australian Aviation College WAAC. At this stage though I'm pretty sure you'll find that the only way to do it is in Europe. The cheapest option is likely to be Bristol with the distance package and the two week refreshers at Cheddar.
As I understand it, there is still nowhere in the world barring maybe a couple of schools in the US that can give JAR licences and even then only on approved courses conducted full time.
I could be wrong but I did some looking at the WAAC thing myself as it all looked very promising... bureaucracy from the JAR end will no doubt hold things up though.
The helicopter school your talking about is Heli-West. They have a tie up with a diploma through WAAC but are no where near delivering JAR licences... mores the pity, It'd be a licence to print money for any operator down under how was prepared to wade through all the
to get through JAR
Good Luck
