1. Gina Rinehart: Net worth $25 to $30 billion (our estimate)
Industry: Mining
Gina Rinehart chairs Hancock Prospecting and is generally regarded as Australia’s richest person. The company owns half of the Hope Downs iron ore mine, run with Rio Tinto, and 70% of the Roy Hill project, with Marubeni, POSCO and China Steel holding the rest. In April 2024 Hancock also disclosed a 5.3% stake in the US rare earths miner MP Materials, 8.8 million shares worth about $337 million at its October 23, 2026 price of $38.30.
How we valued it: Hancock Prospecting is private, so this is our estimate from its mine ownership. It is the one entry on this list not computed from a share price.
2. Anthony Pratt: Net worth $17.7 billion (2015)
Industry: Packaging
Anthony Pratt is executive chairman of Pratt Industries, the largest individually owned manufacturing company in the United States, and chairman of Visy in Australia. In 2020 he bought the Australian assets of Owens-Illinois for A$1 billion, making Visy the country’s largest glass bottle maker.
Both companies are private and no newer public valuation exists, so we show the 2015 figure and flag it.
Valuation basis: Carried over from our 2015 estimate. No inflation applied.
3. Mike Cannon-Brookes: Net worth $11.5 billion
Industry: Software
Mike Cannon-Brookes co-founded Atlassian, which listed on Nasdaq in December 2015 and moved its legal home to the United States in 2022. He became sole CEO in September 2024 and owns roughly 20% of the company. He also runs the family office Grok Ventures, which backs climate projects.
How we valued it: About 20% of Atlassian’s 253 million shares is roughly 50.6 million shares, times $227.61 at the October 23, 2026 close. Other assets are not counted.
4. Scott Farquhar: Net worth $11.5 billion
Industry: Software
Scott Farquhar co-founded Atlassian with Cannon-Brookes and stepped down as co-CEO in August 2024. He remains on the board as a special adviser and also owns roughly 20% of the company. In 2014 he co-founded Pledge 1%.
Valuation basis: Same math as his co-founder: about 50.6 million shares at $227.61 (October 23, 2026 close), so about $11.5 billion.
5. Andrew Forrest: Net worth $11 billion
Industry: Iron ore
Andrew Forrest founded Fortescue and began shipping iron ore to China in 2008. His family interests, the charity Minderoo Foundation and his investment arm Tattarang hold about 36.7% of the company between them. Forrest now also backs green energy ventures.
How we valued it: About 36.7% of Fortescue’s 3.08 billion shares is about 1.13 billion shares, times A$14.27 (October 23, 2026), which is A$16.1 billion, or about US$11.3 billion at 0.7027. Part of that stake is held by his charity, so treat it as an upper bound for his personal holding.
6. Ivan Glasenberg: Net worth $8.8 billion
Industry: Commodities
Ivan Glasenberg led Glencore as CEO from 2002 to 2021 and remains its largest shareholder. He is a South African who also holds Australian citizenship and lives in Switzerland. In April 2025 he bought more shares for the first time in a decade.
Valuation basis: A filing in April 2025 showed 1.219 billion shares, times 537.5 pence at the October 23, 2026 close, which is about 6.55 billion pounds, or about US$8.8 billion at 1.3382.
7. James Packer: Net worth $7 billion (2015)
Industry: Gaming, media
James Packer inherited control of Consolidated Press Holdings from his father Kerry and built the gaming business Crown Resorts, which includes Crown Aspinalls in London. He sold his early media assets over the 2000s, including a 25% stake in PBL Media in 2007 for A$515 million.
Since the 2015 list the Crown ownership has changed, so this figure is certainly out of date.
How we valued it: The 2015 figure stands. Nothing newer is public.
8. Frank Lowy: Net worth $5 billion (2015)
Industry: Shopping centres
Sir Frank Lowy built Westfield into a global shopping centre company and was its chairman until Unibail-Rodamco acquired it in June 2018. He later moved to Israel. His son Steven now leads the family’s football and property interests.
Valuation basis: Unchanged from 2015.
9. Harry Triguboff: Net worth $4.6 billion (2015)
Industry: Property
Harry Triguboff founded Meriton in 1963 and, as of 2015, it had built more than 55,000 apartments and townhouses, making it Australia’s biggest residential developer. He is still the managing director.
How we valued it: Still the 2015 number, for lack of a newer public basis.
10. John Gandel: Net worth $4.3 billion (2015)
Industry: Property
John Gandel built the Sussan women’s clothing chain with his brother-in-law, then bought Chadstone Shopping Centre in Melbourne in 1983 and focused on commercial property.
Valuation basis: Carried over from our 2015 estimate. No inflation applied.

Where a company is listed we multiply shares held by the closing price on October 23, 2026. For private companies we use labelled estimates.
How we estimate net worth
Our estimates are based on public reporting, company valuations, and deal and earnings figures all compiled in an internal valuation model. They are approximate, and figures change over time as new information emerges.
For this list we used shares held, taken from company filings, and closing prices from October 23, 2026. Where companies are private we say so and either estimate or keep the dated 2015 figure.
Last updated: October 2026.
