Wyllie Group

Wyllie Group was founded in 1991 by the late Bill Wyllie after he sold his Hong Kong holdings. Rhonda Wyllie, Melissa Karlson and Luke Wyllie now direct the firm from Perth. The family maintains a national perspective while keeping a flexible approach to asset location and structure. The firm deploys capital across direct equities, managed funds and property. It participates in both passive and active roles, often providing ongoing funding and board support. Confirmed holdings include Perth Convention and Exhibition Centre, Hillarys Boardwalk Retail Precinct, Murray River Farm, 74 Castlereagh Street and North Kellyville Square. Wyllie also holds interests in managed funds focused on public and private equities plus alternative investments. Geographic exposure spans Oceania, Asia and Africa. Investment stages include distressed and turnaround situations as well as growth opportunities. The family office employs a compact team with no disclosed headcount. Additional vehicles include The Rhonda Wyllie Foundation and Be Giving. December 2025: John Van Der Wielen was appointed Non-Executive Chair. The group maintains memberships in Power 500 and the Australian Institute of Company Directors. Wyllie Group operates with a concentrated shareholder base limited to three family members who align on every investment decision. This structure enables rapid execution on direct deals and board-level involvement without external LP constraints. The family also controls operating assets such as Corsaire Aviation and Black Angus cattle operations that sit alongside the investment portfolio.
