Our History

Active Tree Services was founded in 1974 by Mark Willcocks to service residential customers in northern Sydney. Four years later, he began managing trees for Sydney councils.

By concentrating on client-focused service delivery, Mark grew the business and in 1979 he signed the company’s first contract with the NSW transmission corporation, Pacific Power (now TransGrid), to control vegetation under power lines.

Mark has played a key role in the establishment of the Tree Contractors Association of Australia.
