Established by Tony Trevisan in 1980, Tribis (formerly the Transcontinental Group) grew to operate substantial diversified businesses and investments in the mining and oil & gas sectors. It also operates an Australian real estate development and investment business under Iris Residential (formerly TRG Properties). Both companies are now run by Simon Trevisan.
In 2018 the company changed its name to Tribis, reflecting a new era for the privately-owned business. At the same time, the company’s real estate arm was renamed Iris Residential.
Tribis has founded and managed a range of public and private companies, including those listed on major stock exchanges around the world. Iris Residential has residential and commercial property developments in Western Australia, Victoria and Queensland.
