I trained with the old DeBeen guys when they were at Thebarton (2000 til around 2003). Then the old instructor got kind of drug fucked and it all went to hell. I know some of the guys went and formed SABJJ, which is at Prospect and if that is near enough for anyone to train at, it would be worthwhile. The guys are a good bunch.
I don't train there as it is too far from home (live down south). Am keen to check out isohealth though as is closest to home for me I guess, although SDT looks kind of interesting.
