For all those in Sydney, or all of Australia pretty much.

I had trouble finding it at all the usual suspects.

Found these guys on the net - http://www.highperformanceworld.com.au/store/three_bond/

I was skeptical but dropped in as it's close to my work. Asked the guy behind the counter. He didn't blink - "100ml or 300ml?" he says.

Even got a small discount off the listed price. Recommended.
