Ausian,
Refer to the PM I sent you.
But for everyone else.
IMHO, I wouldn't touch a 'grey' import with a 10ft barge pole. However, if you live in Sydney, Melbourne or Brisbane and you buy the bike from the importer, and you don't live to far away, you should be right. But, unless really luck, don't even think about getting parts in the country.
Suzuki DID import the Bandit 250 as an official bike through it's Dealer Network, if you get one of those you'll have less problems. I believe the offical model had RED head covers, but always check the compliance plate just to make sure.
The reason I say "less problems" is that the B250 never really sold well in the land of OZ, that's why Suzuki stopped selling it.
Because you live in NSW, I would suggest you look at one of the bigger LAM bikes, that is unless you suffer from ducks disease, or have little or no intention of riding outside the city.
