Hayes Knight

Greg Hayes started JG Hayes & Co in the early 1980s. The practice advanced to a partnership by the early 1990s, adopted the Hayes Knight name, opened a Sydney CBD office and shifted to a corporate structure in the early 2000s. Wealth traces to this expansion of an accounting practice into advisory services for families. Services cover tax and accounting for fast-growth businesses, mid-size corporates, self-managed superannuation funds and not-for-profits. Investment types include private equity, natural resources and philanthropic or mission-related allocations. Activity remains concentrated in Oceania. The firm belongs to the Morison Global association. Greg Hayes previously served as Managing Director of Easton Investments. Lisa Armstrong, his daughter, holds a director role at Hayes Knight while leading Knowledge Shop. Adjacent vehicles include School for Life Foundation, Knowledge Shop Pty Ltd and Merit Wealth Pty Ltd.
