Trevor established Kareela Aviation Pty Ltd in 1978, as an aircraft maintenance business. In 1999, Trevor supplemented this successful venture by fulfilling the need for a medium-size multi-role helicopter in the Australian Aerial Firefighting industry, and thus Trecked Pty Ltd (trading as Helitreck) was born.

Trevor is a Licenced Aircraft Maintenance Engineer, and holds his Australian Private Pilot License in both rotary and fixed wing aircraft. Trevor also holds a Heavy Combination Licence, Dangerous Goods Licence and various classes of Work Cover Licence. He has extensive first hand knowledge of the aviation and transport industries.

During his 45 years in the aviation industry, Trevor has obtained operational experience including remote area helicopter operations, aerial fire fighting, large budget film and media work, and government and corporate charter. Additionally, he has been an advisory to the Civil Aviation Safety Authority and his flight characteristics and engineering expertise has been called upon to support prosecution and defence in legal proceedings.
