Si-Hing Otto Heutling is one of the highest and most experienced instructors directly under Master Si-Fu Stefan Fischer, the Australian Chief Instructor for Wing Tsun. His martial arts career began more than 20 years ago at the age of six with Judo. The arts of Boxing and Wing Chun were next whilst living in Sydney for three years as a child. On his return to Germany he began studying Karate before moving on to Jeet Kune Do and then Kick Boxing. While all these arts had their strong points and Otto had trained under instructors that were certainly impressive in one way or another, he was not quite satisfied, still searching for the "ultimate" self-defence system.

Only after reading "On Single Combat" by Grandmaster Keith R. Kernspecht he was convinced he had found it, without even seeing it before. He was astonished by the logic and simplicity of the Leung Ting system that seemed to have all the advantages that other styles lacked. Everything made sense and nothing was left to chance. All this was confirmed after seeing a demonstration of his later Si-Fu. The control and speed was unparralleled by anything he had seen before. Otto joined the WingTsun classes in Maroubra and only a few months later became the first Australian full-time student.

One year later Otto started teaching himself, taking classes in Maroubra and Hurstville and assisting Sifu Fischer at the new headquaters in Randwick. He now runs his own school in Parramatta but has also spent time conducting seminars interstate and representing the AUEWTO with demonstrations at various martial arts expos and tournaments. In 2001 he won the title in the division of best self-defence demonstration at the 4th. Annual Australian Martial Arts Championships at the States Sports Centre in Homebush.
