Antony William Paul Sage, better known as Tony Sage (born 26 June 1960), is a Western Australian businessman. Starting in funds management and accounting, he financed and managed various mining companies in Australia and overseas, and is a prominent player in the state's resources industry. He is also the sole owner and chairman of Perth's A-League soccer team, Perth Glory, and has business interests in fashion and entertainment.
Born in Gloucester, England, on 26 June 1960, Tony spent his early childhood regularly travelling between England and his mother's hometown of Salerno in Italy. His family moved to Australia in 1967 and spent short stints living in Adelaide, Melbourne and Sydney before heading to New Zealand in 1975. A few years later in 1978, Tony returned to Australia to attend Churchlands College (now part of Edith Cowan University) in Perth where he graduated with a Bachelor of Business (Accounting and Finance) in 1980. He later became a Fellow of the Association of Certified Practising Accountants, a Chartered Accountant, and a Fellow of the Taxation Institute of Australia. He has three children Jessica, Emily and Matthew.
Sage acted as funds manager for property trust group Growth Equities Mutual Limited in Western Australia. From the mid-1990s onward, he financed and managed a range of listed mining and exploration companies including Cape Lambert Resources, African Petroleum, Cauldron Energy, Gabriel Resources, International Petroleum, International Goldfields, Fe Limited, Chameleon Mining and African Iron.
In 2008, Sage sold the Cape Lambert iron ore project in the Pilbara region of Western Australia for A$400 million to Chinese firm, China Metallurgical Group Corporation. The project had been purchased two years earlier for approximately A$20 million and during the 24 months that followed, Cape Lambert Iron Ore Ltd spent approximately A$50 million on exploration activities.
He was a founder of radio network Red FM, which was later sold to WA Newspapers Limited for a considerable profit, and is also a former owner of the West Perth nightclub, Onyx Bar, which opened in 2005. In June 2008, Sage purchased a 49 per cent stake in the Perth Fashion Festival.
In 2007, Sage became one of a triumvirate of owners of the A-League soccer team Perth Glory. He became the outright owner in February 2009.
