Northern Wu Style taijiquan 

This shifu appears to have either stopped teaching or just teaches locally, I have been unable to find anymore information, quite a lot of Chinese teachers find it a struggle in Australia and return to China, it happens to quite a lot. Australia is not big on Martial arts generally, there is a small taiji community generally. Australia favors UK sports like boxing and cricket, and Rugby and Soccer, The Asian community is roughly about 30% of most cities in Australia now, and Chinese is the biggest community, but they tend to have their own separate taiji community, as 2 of Wu Ying Hua and Ma Yueh Liang's children live and teach exclusively to the local expat Chinese community here or did 4 or 5 years ago in Sydney, they are impossible to locate, without knowing someone in the community. This gentleman appears to be of the lineage of Wu jianquan's father, Wu quanyu who had students created a Beijing line of Wu style.
