Warburton Group
Warburton Group traces its roots to 2004 when Tim Roberts organized the family office around the construction and property legacy built by his late father John Roberts through Multiplex. The structure incorporates Warburton Giving as a dedicated philanthropic vehicle. Investment activity covers hedge funds, infrastructure, natural resources, private equity and real estate. The firm executes through direct holdings, fund commitments and co-investments. Confirmed positions include the Perth Girls School Redevelopment in East Perth, the Mundijong Cattle Enterprise in Baldivis, the Queenstown Residence in New Zealand, the Perth Jet Centre at Perth Airport and multiple Bombardier and Bell aircraft. Geographic reach extends to Africa, Asia, Europe, North America, South America, the Caribbean and the Middle East. The team includes business partners Rod Hamersley and Adam Zorzi, who collaborate on projects such as the Perth Girls School redevelopment. Darren Weaver serves as Non-Executive Chair. Warburton Group maintains memberships in the North Cottesloe Surf Lifesaving Club, the Perth Symphony Orchestra and the Channel 7 Telethon Trust, where Tim Roberts holds patron or trustee roles. The office operates with a hybrid mandate that blends legacy real-asset holdings with venture and growth allocations in consumer tech and enterprise software. This architecture separates operating businesses such as AvWest Aviation and Western Rock Lobster licences from the core investment portfolio while preserving family control over deployment decisions.
