Q&A with Lachlan

What inspired you to join Redleaf?
“I joined after university because Redleaf offered diverse projects and meaningful work. Three years in, I’ve been fortunate to work on incredible projects—from snorkelling with platypus to conducting thousands of hectares of flora surveys.”

A project you’re proud of?
“Confirming the presence of State and National environmental matters in a tributary of the Brisbane River. My surveys helped guide the client to an environmentally responsible and compliant project outcome.”

Favourite ‘wait… really?’ ecology fact?
“Many Australian birds and marsupials depend on tree hollows that take hundreds of years to form. Old-growth trees underpin entire ecosystems.”

What keeps you energised outside work?
“Hiking and wildlife photography across the national parks of South East Queensland.”
