DMMA - ...BJJ politics in Oz have settled down considerably. Everyone is basically doing there own thing.
It seems to work OK as well. I've never had any dramas doing casual sessions (work travel) at any club in the country. Even here in Canberra, we've had Renato Vieira setup. He was happy for us to visit for a session or two, but was clear about 'this team or that team, not both' which I have no problem with.
As DMMA said, we Machado folk have our 'Asia-Pacific' tournament, but it's just as much an opportunity to jam us all in the one venue for a bit of a roll, a few gradings and some good times. Funny thing with Will-Machado being so big these days, the 'get together' looks like a Machado invasion every year :)
