Executive Chairman
Mark Willcocks

In 1974 Mark started a small business, which has since grown into Active Tree Services, an industry leading organisation with hundreds of employees and contractors working in all Australian states. For most of this time, Mark has been the managing director.

Since the appointment of a professional CEO in 2002, Mark has continued his "hands on" involvement by working closely with the leadership team of the business and contributing to operational and strategic activities on a daily basis.

At an industry level, Active Tree Services and Mark have been instrumental in bringing together tree contracting organisations through leadership of industry bodies and sponsorship of Arboriculture Australia and Utility Arborist Association of Australia.

Mark has played a key role over several years in the development of an industry code of practice and other standards for the industry that has raised the professionalism and safety levels of operators across the board.

In 2012 Mark was selected by Australian Arbor Age as the first Living Legend of the Australian tree industry. In 2004 Mark was awarded the Ernst and Young Entrepreneur of the year for the services industry in NSW. In 2011 he invented the Bushi, a remote controlled boom saw.

His passion for the business and the industry is unabated, and Mark enjoys nothing more than travelling around the company’s field operations, talking to employees and subcontractors and listening to their suggestions for improving the business.

Mark holds a Bachelor of Engineering degree from Sydney University.
