G`day mate
One thing i`ve found is that there are plenty of places to get the parts here in oz, but they are the same parts you get from O/S suppliers only they have covered their costs and profit and you can get them cheaper from the original supplier.
The price of parts here is a rip off, up to three times the price from a UK or US supplier.
Go check out the FAQ section, theres a list of suppliers in there for just about anything you may need.
Failing that try your local honda dealer.
Cheers
