Great Southern Group was a group of Australian companies that was notable as the country's largest agribusiness managed investment scheme (MIS) business. The company was founded in 1987 and became a public company in 1999. It expanded its MIS business rapidly in the 2000s, supported by favourable tax regulations for these types of investments. Most of the Group's business was in plantation forestry to supply woodchips for the pulp and paper industry, but in the 2000s it diversified into high-value timbers, beef cattle, olives, viticulture, and almond production. The company's after-tax profit peaked at A$132 million in 2006, but by 2008 had deteriorated to a A$63 million loss.
