Okay- I shall admit that his accent is not even nearly Australian, but his regular use of the F-word in his videos distinguishes him from other internet masters the same way Gordon Ramsay's language makes him distinguishable from all the other chefs on the Food Channel. :D
Most of the videos I have seen of him demonstrate street fighting moves with a strong Wing Chun basis. I loved this one Taijiquan video I have seen of him today, though.
Master Wong's no-nonsense approach to teaching appeals to those students who do not wish to embark on an academical exercise in learning martial arts and will suit those who are primarily interested in learning martial arts for self defense.
I have subscribed to his Youtube channel. Below are some links to videos of his. :)
