Oceania may have a much smaller population than Asia, Europe or North America. Still, it is home to several multibillion-dollar fortunes built through real estate, mining, manufacturing, software, packaging, automobile components, shopping centres and media.
For this ranking, Oceania includes Australia, New Zealand and the Pacific island nations. To remain consistent with the previous articles in this series, the ranking primarily follows citizenship, rather than requiring the billionaire to currently live in Oceania.
The figures below use the latest Forbes estimates available in late August 2026. Australia’s Forbes real-time rich list was updated on August 29, while individual Forbes profiles were used to check the figures and identify New Zealand billionaire Graeme Hart. Billionaire fortunes can change daily, so these values should be treated as a dated snapshot. (Forbes Australia)
1. Harry Triguboff — $23.5 Billion
Country: Australia
Main source of wealth: Real estate
Estimated net worth: $23.5 billion
Harry Triguboff is the richest man in Oceania based on Forbes’ late-August 2026 estimates.
Forbes Australia valued him at approximately $23.5 billion on August 29, 2026. (Forbes Australia)
Triguboff is the founder and managing director of Meriton, one of Australia’s largest residential property developers.
He was born in Dalian, China, to Russian parents and moved to Australia as a teenager.
Triguboff recognised relatively early that Sydney’s growing population would create strong demand for high-density apartment living. Forbes reports that his company has constructed more than 79,000 apartments. (Forbes)
His heavy emphasis on apartment towers earned him the nickname “High-Rise Harry.”
Meriton has been particularly active in Sydney and southeast Queensland, including the Gold Coast.
At 93 years old in 2026, Triguboff remains one of Australia’s most successful self-made property developers.
2. Andrew Forrest & Family — About $18 Billion
Country: Australia
Main source of wealth: Mining
Estimated net worth: approximately $18 billion
Mining magnate Andrew Forrest ranks second among Oceania’s richest men.
Forbes Australia’s August 29 real-time list valued Forrest and his family at approximately $18 billion. (Forbes Australia)
Forrest founded Fortescue Metals Group in 2003.
Fortescue developed into one of the world’s major iron-ore producers, operating huge mining projects in Western Australia.
Forbes valued Forrest at $20.1 billion when it compiled Australia’s 50 Richest list in February 2026, before subsequent market movements lowered the real-time estimate. (Forbes)
Forrest has increasingly pushed Fortescue toward renewable and green-energy projects.
His privately owned Squadron Energy also acquired Australian renewable-energy company CWP Renewables in a transaction Forbes estimated at about A$4 billion. (Forbes)
Forrest is also heavily involved in philanthropy through the Minderoo Foundation.
3. Anthony Pratt — $12.1 Billion
Country: Australia
Main source of wealth: Packaging and manufacturing
Estimated net worth: $12.1 billion
Australian businessman Anthony Pratt ranks third with an estimated fortune of approximately $12.1 billion as of August 27, 2026. (Forbes)
Pratt is executive chairman of Visy Asia-Pacific, the packaging and recycling company established by his grandfather in Melbourne in 1948.
The business was later expanded dramatically by his father, Richard Pratt.
Anthony Pratt also owns Pratt Industries in the United States, which Forbes describes as the largest U.S. manufacturer of corrugated cardboard. (Forbes)
Packaging may seem less glamorous than software or mining, but the enormous scale of consumer-goods distribution has made the industry extremely valuable.
Pratt’s sisters, Heloise Pratt and Fiona Geminder, also own interests in the family businesses and are billionaires.
4. Mike Cannon-Brookes — About $11.7 Billion
Country: Australia
Main source of wealth: Software
Estimated net worth: approximately $11.7 billion
Technology entrepreneur Mike Cannon-Brookes is Oceania’s richest male technology billionaire.
Forbes Australia placed his fortune at approximately $11.7 billion on August 29, 2026. (Forbes Australia)
Cannon-Brookes cofounded Atlassian with Scott Farquhar shortly after the two graduated from university.
The pair famously funded the young company partly using credit cards.
Atlassian developed software products used by companies and software-development teams around the world.
Cannon-Brookes remains the company’s chief executive.
He has also invested heavily in renewable energy. Among his other investments are Sun Cable and a minority interest in Australian energy company AGL Energy. (Forbes)
Forbes had valued him at $10 billion when it published Australia’s 50 Richest ranking earlier in 2026, demonstrating how quickly technology-linked fortunes can move. (Forbes)
5. Scott Farquhar — About $11.4 Billion
Country: Australia
Main source of wealth: Software
Estimated net worth: approximately $11.4 billion
Scott Farquhar, Cannon-Brookes’ Atlassian cofounder, follows closely with approximately $11.4 billion on Forbes Australia’s August 29 real-time list. (Forbes Australia)
Farquhar and Cannon-Brookes built Atlassian from a startup into one of Australia’s most internationally successful technology companies.
Forbes reports that major companies including Costco and Delta Air Lines use Atlassian products. (Forbes)
Farquhar stepped down as Atlassian’s co-chief executive in September 2024 to spend more time with his family and concentrate on philanthropic activities.
He remains involved with the company as a board member and adviser.
Forbes estimated his wealth at $9.7 billion in its February 2026 Australian ranking, before it subsequently increased. (Forbes)
6. Graeme Hart — $10.1 Billion
Country: New Zealand
Main source of wealth: Packaging
Estimated net worth: $10.1 billion
Graeme Hart is the richest person in New Zealand and the only New Zealander to enter this top 10.
Forbes estimated his fortune at approximately $10.1 billion as of August 29, 2026. (Forbes)
Hart built his fortune primarily through leveraged buyouts.
Rather than creating a famous consumer-facing company, he acquired industrial and packaging businesses and combined them into a large international packaging empire.
His companies manufacture everyday products including:
- milk cartons,
- water bottles,
- aluminium foil and
- paper packaging.
In April 2025, Hart sold his 77% stake in publicly traded Pactiv Evergreen to packaging company Novolex for approximately $2.5 billion, according to Forbes. (Forbes)
Hart’s inclusion is important because a list of Oceania’s richest men should not simply reproduce Australia’s rich list.
7. Vivek Chaand Sehgal — About $9 Billion
Country: Australia
Main source of wealth: Automobile components
Estimated net worth: approximately $9 billion
Vivek Chaand Sehgal had a Forbes-estimated fortune of approximately $9 billion in late August 2026. (Forbes)
Sehgal is chairman of the Motherson Group, one of the world’s largest automotive-component manufacturers.
He established the business with his mother in 1975.
Forbes reports that Motherson generates approximately $23 billion in annual revenue, with customers including BMW, Ford, Mercedes-Benz, Toyota and Volkswagen. (Forbes)
Sehgal currently resides in Delhi, India, but Forbes explicitly identifies his citizenship as Australian. (Forbes)
He is therefore included under the citizenship-based methodology used in this series.
His case also shows why geographic billionaire rankings require a clearly stated definition: residence and citizenship do not always point to the same continent.
8. Frank Lowy — $8.7 Billion
Country: Australia
Main source of wealth: Property and investments
Estimated net worth: $8.7 billion
Shopping-centre pioneer Frank Lowy ranks eighth with an estimated fortune of approximately $8.7 billion on August 29, 2026. (Forbes)
Lowy cofounded the business that became Westfield, one of the world’s largest shopping-centre groups.
His story began much more modestly.
A Holocaust survivor, Lowy opened his first shopping centre in Sydney in 1959.
Westfield subsequently expanded internationally.
In 2018, Lowy sold Westfield Corporation to Unibail-Rodamco in a deal worth approximately $16 billion, which Forbes describes as Australia’s largest takeover at the time. (Forbes)
Today, the Lowy family primarily manages its wealth through the Lowy Family Group, which has offices in Sydney, Los Angeles and New York.
Lowy is an Australian citizen, although Forbes lists his current residence as Tel Aviv, Israel. (Forbes)
9. Cliff Obrecht — $7.6 Billion
Country: Australia
Main source of wealth: Canva/software
Estimated net worth: $7.6 billion
Australian technology entrepreneur Cliff Obrecht ranks ninth with approximately $7.6 billion.
He cofounded Canva with Melanie Perkins and Cameron Adams.
Forbes reports that private investors valued Canva at approximately $42 billion in August 2025. (Forbes)
The company provides online design tools used to create presentations, social-media graphics, documents, posters and numerous other forms of visual content.
Forbes estimates that Obrecht and Perkins each own approximately 18% of Canva. (Forbes)
The couple has also pledged to transfer the overwhelming majority of their Canva holdings to charitable causes through the Canva Foundation. Forbes reported in July 2026 that they were developing further philanthropic initiatives connected to that commitment. (Forbes)
Forbes Australia’s August 29 real-time ranking placed Obrecht at approximately $7.6 billion. (Forbes Australia)
10. Kerry Stokes — $7.2 Billion
Country: Australia
Main source of wealth: Construction equipment, media and investments
Estimated net worth: $7.2 billion
Australian businessman Kerry Stokes completes the top 10 with an estimated fortune of approximately $7.2 billion as of August 29, 2026. (Forbes)
Stokes built his fortune through a range of businesses.
He began his career selling Caterpillar tractors and trucks before eventually expanding into media.
His wealth is now closely associated with SGH, formerly Seven Group Holdings.
SGH has interests in sectors including:
- industrial services,
- construction equipment,
- mining services and
- media.
In 2024, SGH acquired Australian concrete and asphalt producer Boral in a transaction valued at A$4.4 billion. (Forbes)
Stokes retired as chairman of Seven Group Holdings in 2021. His son Ryan Stokes now serves as chief executive and managing director of SGH.
Top 10 Richest Men in Oceania at a Glance
| Rank | Name | Country | Main source of wealth | Late-August 2026 estimate |
|---|---|---|---|---|
| 1 | Harry Triguboff | Australia | Real estate | $23.5 B |
| 2 | Andrew Forrest & family | Australia | Mining | $18.0 B |
| 3 | Anthony Pratt | Australia | Manufacturing/packaging | $12.1 B |
| 4 | Mike Cannon-Brookes | Australia | Software | $11.7 B |
| 5 | Scott Farquhar | Australia | Software | $11.4 B |
| 6 | Graeme Hart | New Zealand | Packaging | $10.1 B |
| 7 | Vivek Chaand Sehgal | Australia | Auto components | $9.0 B |
| 8 | Frank Lowy | Australia | Property/investments | $8.7 B |
| 9 | Cliff Obrecht | Australia | Canva/software | $7.6 B |
| 10 | Kerry Stokes | Australia | Industrial/media | $7.2 B |
Combined estimated wealth: approximately $119.3 billion.
These figures represent a late-August 2026 snapshot and may change as markets and business valuations change.
Why Gina Rinehart Is Not Number One Here
Anyone familiar with Australian wealth may immediately notice one major name missing: Gina Rinehart.
She has not been overlooked.
In fact, Rinehart is currently the richest person in Australia.
Forbes Australia estimated her fortune at approximately $25.6 billion on August 29, 2026, putting her ahead of Harry Triguboff. (Forbes Australia)
She is excluded solely because this article ranks the richest men.
Rinehart will therefore be the leading figure in the companion article on the Top 10 Richest Women in Oceania in 2026.
Australia Dominates Oceania’s Billionaire Wealth
Nine of the 10 men in this ranking are Australian citizens.
The only exception is New Zealand’s Graeme Hart.
Australia’s dominance is not surprising. Forbes Australia reported that the collective wealth of its 50 richest people reached approximately $254 billion in its February 2026 ranking. (Forbes)
By August, Forbes Australia’s real-time list had expanded to 57 billionaires, demonstrating how substantial the country’s billionaire population has become. (Forbes Australia)
No billionaire from smaller Pacific island nations currently has enough wealth to approach the top 10.
Mining and Natural Resources Remain Important
Australia’s huge mineral resources have created many of the continent’s largest fortunes.
Andrew Forrest built his wealth through iron ore.
Gina Rinehart, although excluded from the men’s list, also became enormously wealthy through mining.
Other Australian billionaires outside this top 10 include Clive Palmer and several iron-ore heirs. Forbes estimated Palmer’s fortune at approximately $4.1 billion in late August 2026. (Forbes)
The mining industry therefore remains one of Oceania’s most important generators of billionaire wealth.
Technology Is Becoming Much More Important
Oceania’s rich list is no longer dominated entirely by property, mining and traditional industry.
Three men in the top 10 have fortunes tied primarily to software:
Mike Cannon-Brookes, Scott Farquhar and Cliff Obrecht.
Cannon-Brookes and Farquhar cofounded Atlassian, while Obrecht cofounded Canva.
Forbes Australia’s real-time list also includes Canva cofounder Cameron Adams and WiseTech founder Richard White among the country’s billionaires. (Forbes Australia)
This indicates a gradual shift in Australian wealth creation toward software, cloud services, digital design and technology.
What About Mario Verrocchi?
Chemist Warehouse cofounder Mario Verrocchi has also become one of Australia’s wealthiest businessmen.
Forbes Australia valued him at approximately $5.8 billion on its August 29 real-time list, placing him below Kerry Stokes and therefore outside this Oceania top 10. (Forbes Australia)
Verrocchi helped build Chemist Warehouse, which now operates hundreds of pharmacy outlets across Australia and international markets.
The business completed a merger with publicly traded Sigma Healthcare in 2025. (Forbes)
What About John Gandel?
Australian shopping-centre billionaire John Gandel is another notable near-miss.
Forbes estimated his fortune at approximately $4.6 billion in late August 2026. (Forbes)
Gandel owns half of Chadstone Shopping Centre in Melbourne, which Forbes describes as the largest shopping mall in the Southern Hemisphere.
His fortune is substantial but remains well below the roughly $7.2 billion required to enter this top 10.
Why Citizenship Matters
Several names in this article demonstrate why geographic billionaire rankings need a consistent methodology.
Vivek Chaand Sehgal lives in India but is an Australian citizen.
Frank Lowy currently resides in Israel but holds Australian citizenship.
Forbes’ Australian rich list itself can sometimes include individuals on the basis of business, residential or citizenship ties rather than citizenship alone. (Forbes)
For this article, I have therefore prioritised Forbes-listed citizenship in an Oceanian country, while using Forbes Australia’s real-time ranking as a key source of current wealth figures.
This approach is consistent with the methodology used in the preceding South American articles.
Why Net Worth Figures Change
A billionaire’s net worth is not the same as the amount of money sitting in a bank account.
Most of these fortunes consist largely of:
- company shares,
- private-company ownership,
- property,
- investment portfolios and
- other business assets.
Forbes Australia explains that the value of publicly traded holdings in its real-time billionaire tracker can be updated every few minutes while markets are open, while fortunes tied substantially to private companies are generally adjusted less frequently. (Forbes Australia)
This explains why Andrew Forrest, for example, was worth approximately $20.1 billion on Forbes Australia’s February ranking but about $18 billion in the August 29 real-time ranking. (Forbes)
Billionaire lists therefore need a valuation date to remain meaningful.
Conclusion
Harry Triguboff is the richest man in Oceania in late August 2026, with Forbes estimating his fortune at approximately $23.5 billion.
Mining billionaire Andrew Forrest follows at approximately $18 billion, while packaging magnate Anthony Pratt ranks third at $12.1 billion.
Technology billionaires Mike Cannon-Brookes and Scott Farquhar come next, followed by New Zealand’s Graeme Hart, Australian citizen Vivek Chaand Sehgal, Frank Lowy, Canva cofounder Cliff Obrecht and Kerry Stokes.
Together, these 10 men have an estimated combined fortune of approximately $119.3 billion.
The ranking also illustrates the changing nature of wealth in Oceania. Mining, property and manufacturing remain enormously important, but software businesses such as Atlassian and Canva have created a new generation of multibillion-dollar fortunes.
As always, these rankings should be understood as dated financial estimates rather than permanent measurements of personal wealth.
Disclaimer
This article is provided for general informational and educational purposes only.
Net worth figures are estimates based primarily on Forbes and Forbes Australia billionaire data available in late August 2026. They should not be interpreted as exact amounts of cash personally held by the individuals named.
For consistency with other articles in this continental series, individuals are classified principally by citizenship in an Oceanian country. Some people included in the ranking, such as Vivek Chaand Sehgal and Frank Lowy, currently reside outside Oceania.
Billionaire fortunes can change substantially because of stock-price movements, exchange rates, private-company valuations, asset sales, acquisitions and other financial developments. Some figures identified as “& family” may include wealth associated with family members rather than assets controlled solely by the named individual.
The information was checked against credible publicly available sources at the time of writing. Readers are encouraged to independently fact-check the information and consult Forbes, corporate filings, stock-exchange disclosures and other authoritative financial sources for the latest figures.
