More about

Sifu Leung

Sifu Jack was born in 1977 in Hong Kong. As a kid, he was a huge fan of Kung Fu and action movies.

As a young child, Jack started martial arts training, at first informally in Judo and then progressed to Karate. He trained in Goju-Ryu Karate for 6 years, and in his early teens, won third place in his weight division, in a Karate Kumite (Free fight) competition in Hong Kong.

As a teenager, Jack became interested in Kung fu after one of his best friends had returned from a trip to Australia and showed him some Kung fu techniques in Southern Preying Mantis, a Chinese martial art form. He was amazed at the short distance combat way of fighting in Kung fu compared to the far distance way in Karate. In 1995, after extensively researching traditional styles of Kung fu in his home district, he discovered Kwong Sai Jook Lum Tong Long (Bamboo Forest Southern Preying Mantis) in Tai Po, Hong Kong, where he relocated and trained for over a year.

One day in 1996, on his way to school, he stopped by the Wing Chun Association located in Prince Edward, where he was fortunate enough to meet Grandmaster Wan Kam Leung. He was so impressed with the style of Kung fu that he decided to start training. During the first 6 months, Jack was still training in Karate while doing Wing Chun. During a sparring match one day, he ended being matched up with a Karate senior who was bigger and older than him, who was one of the strongest fighters in the dojo at the time and who also happened to be the son of the Karate Sensei. With the limited Wing Chun techniques he had learnt in 6 months, he managed to overcome their difference in size and manipulated his opponent easily.

After the session, Jack decided to quit Karate and only train in Kung fu, because he believed this to be the fundamental element of self defence – People who pick on you, are usually larger in size, armed with weapons or outnumber you.

Jack learnt the system directly from Sigung Wan Kam Leung in Hong Kong and finished Wooden Dummy level before he left for Australia.

Jack moved to Australia to further his tertiary studies, He travelled back and forth to a new school in Jordan for training and maintained a close bond with his Sifu.

While in Australia, he could not find a Wong Shun Leung system Wing Chun in Queensland, so due to work studies and commitments he stopped training for a year. When he explained the reason he had stopped training to his Sifu, he was encouraged by his Sifu keep training martial arts, regardless if it was another form of Martial Arts. “A martial artist should never rest his training, he should always keep the Kung fu spirit alive” said Sifu Wan.
Encouraged, Jack started training Chow Gar Tong Long (Southern Preying Mantis), continued for a few years under different lineages to broaden his Kung fu views and knowledge.

In 2008, he developed an interest in fitness and started training in Muay Thai. While still living in Thailand, he travelled overseas another 4 times. This was in preparation for a ring fight which was to be held at a local stadium in Phuket, Thailand.

Unfortunately after a severe elbow injury in Thailand, Jack had to give up his fight. During training, his trainer partner dropped his guard, Jack elbowed his mouth with a reverse back elbow, which resulted in the trainer receiving 21 stitches, and caused Jack to lose the flesh from his elbow. As a result, he had limited arm and elbow movement for over a month. He was told by the doctor that the tendon lost from his elbow will not repair and it will limit his movements on his elbow.

After the accident, Jack started looking for a martial art that he could train for life, rather than one where that he willl constantly need to be in good shape (external martial arts that rely heavily on muscle mass, speed and weight). He looked for a system that does not require brute force or huge strength. A style that he could use to protect himself as he grew older (or in another word 'slower'). A self defence system that enables a smaller, weaker person – an older man, a female to defeat a bigger, stronger opponent. He realised that an older man could not match a younger man’s stamina in a long fight. Just like it is harder for a female to match against a male opponent’s strength.

Efficiency in Wing Chun is based on the concept that the shortest distance between two points is a straight line. Likewise its primary targets all lie along the centre line of one’s opponent. Wing Chun training is designed according to an individual’s situation, and therefore is suitable for both males and females of all ages, fitness and strengths. It’s all about Physics, the correct angle and force together with the sensitivity of hands. Just like learning how to drive a manual car. Once you know how to drive, you do not have to think about it anymore. You simply just drive. 

The solution was simple, it matches Practical Wing Chun. So once again Jack started training intensively in Hong Kong. In 2013 he was certified to teach Practical Wing Chun and he serves as a Regional Director for Practical Wing Chun Australia. Under the 17 years guidance of Grand Master Wan Kam Leung. He was awarded the title – ”Sifu” (Chinese for instructor).

In 2016, Sifu Jack was inducted by Grand Master Wan Kam Leung as an closed door disciple.
Sifu Leung currently runs 8 branches in Queensland and workshops/seminars around the world to promote the art of Practical Wing Chun.

Queensland Chief Instructor Jack Leung serves as the Regional Director for Wan Kam Leung Practical Wing Chun Kungfu in Australia.

Before moving to Australia, Jack Leung trained & competed in Goju-Ryu Karate in Hong Kong for 6 years. He also trained Muay Thai in Thailand and several lineages of Southern Praying Mantis, including Chow Gar & Jook Lum Tong Long. In 1996, he was fortunate enough to meet Grand Master Wan Kam Leung in Hong Kong and started training at the Ving Tsun Association.


Practical Wing Chun is a close range combat & self defence system that does not pit force against force. Jack constantly cross train with different martial artists and mentors in other martial arts disciplines. After 17 years of training and guidance under Grand Master Wan he was awarded the title of Sifu in 2013. Sifu Leung now serves as Regional Director for Practical Wing Chun Australia.
