Sifu David Peterson's close contact with Sifu Wong Shun Leung and his reputation as an instructor of Wong Sifu's Wing Chun Kung Fu has seen him lecture and teach all over the world.

In 1998, Peterson was invited to America for the first time by Sifu Jesse Glover, the late Bruce Lee's original student, teaching in both Seattle and Los Angeles.

In November 1999, Peterson was a guest presenter at the '1st World Ving Tsun Conference' in Hong Kong, presenting his views on the future of the Wing Chun system.

His close relationship with Sifu Wong, saw him honoured with the invitation to speak at his teacher's funeral.

A highly respected seminar presenter of the ‘WSL Method’ of Wing Chun, both in Australia and overseas, Peterson travelled to the USA for a second time in 2000 to conduct seminars and workshops at the 'Ving Tsun Museum' in Dayton, Ohio, and to an enthusiastic group of Wing Chun and JKD enthusiasts in Orlando and Fort Myers, Florida.

In July 2003, on the invitation of devotees of the ‘WSL Method’ there, he travelled to the UK for the first time, conducting seminars and workshops in Manchester, Newcastle-Upon-Tyne, Southampton and London (St Albans). While there, he was interviewed by both ‘Combat’ and ‘Martial Arts Illustrated’ magazines, two of Britain’s most prominent martial arts journals. As a result of the success of this trip, a second trip to the UK took place in September with seminars and workshops being presented in Whitley Bay, and again in both Newcastle and Manchester. A third trip to the UK took place in April of this year (2005), followed by yet another in July to both Manchester and Southampton. So successful was that visit, that he has been invited back to both places again this coming September by the ‘Stockport Wing Chun Academy’ (sifu Ged Kennerk) and the ‘Wing Chun Federation’ (sifu Alan Gibson)!

In 1996 Sifu Peterson was employed as script translator on Jackie Chan's "Mr Nice Guy" which was shot on location in Melbourne.

Peterson is the author of ‘Look Beyond the Pointing Finger: the Combat Philosophy of Wong Shun Leung’, the first-ever English language book on his teacher’s interpretation of the Wing Chun system, first published in September of 2001.

He is also a freelance writer whose articles have appeared in many local (Australian) and overseas journals, including ‘Combat’, ‘Inside Kung-fu’, ‘Black Belt’, ‘Masters of the Martial Arts’, ‘Impact: the Action Movie Magazine’, ‘Eastern Heroes’, ‘Australasian Fighting Arts’, ‘Blitz Australasian Martial Arts Magazine’, ‘Traditional Martial Arts Journal’, ‘Impact Martial Arts Magazine’, ‘Qi Magazine’, ‘Australasian Martial Arts Magazine’, ‘Martial Arts Illustrated’, ‘Kung Fu Qigong Magazine’, ‘Fight Times’, ‘Ging Wing Chun’, ‘Kicksider’ and ‘Kung-fu Illustrierte’. More recently, his articles have featured on several international Web sites, including 'wingchunkuen.com’, ‘Planet Wing Chun’, ‘Wing Chun World’, ‘vtmuseum.org’ and ‘WongShunLeung.com’.
