Hi SkyPilot

The main Aussie distributor for ENYA is:

http://www.modelflight.com.au/powered_enya_engines.htm

The prices are still high, compared to what you may be used to in the 'States.

ModelFlight are a major distributor of R/C items in Australia. They sell direct to buyers in the US.
I have had good dealings with them.

The larger ENYA engines (1.55 Four stroke, 1.80 Two Stroke) are also available in Australia from a
hobby shop specialising in pattern, the name of which presently escapes me.

Cheers
