Mike two places I would check in Australia first:-
Online:-

Touchy/Feely Shop: -
My favourite "photographic candy store" G&V Imaging (400 George St Sydney ) who are very competative on price and carry a good/huge range in stock.
I got my MF486 compact ball head from there same price as online store above.
Their website is a bit average - no prices and only shows consumer items, dont let the website put you off.
