Business News has ranked Western Australia's 100 largest privately owned businesses by revenue for the first time, uncovering a combined turnover of more than $80 billion across a broad cross-section of the state's economy.
The inaugural Top 100 Private Businesses publication, which launches on Monday, profiles the companies operating behind the disclosure requirements of public markets — from mining contractors and grain handlers to health insurers, car dealerships and aged care providers.
Close to 200 business leaders got their first look at the publication on Wednesday night during an exclusive preview event at the new One Two Five by Hub office in Brookfield Place.
The top ten
Hancock Prospecting tops the inaugural Top 100 list with $11.6 billion in revenue, anchored by its interests in the Roy Hill iron ore operation in the Pilbara.
The Gina Rinehart-led group recorded a $3.1 billion profit over FY25 and employs nearly 3,000 people.
Perth-founded online gaming company VGW Holdings ranks second at $6.1 billion, followed by grain cooperative CBH Group at $5.8 billion.
CBH, Australia's largest cooperative, handles about 90 per cent of grain in Western Australia and recently invested around $590 million in its network infrastructure.
Not too far behind, construction group Multiplex, founded in Perth in 1962 and now owned by Canada's Brookfield, sits fourth with $4.0 billion in revenue from more than 1,150 projects delivered globally.
And rounding out the top five is Swift Holdings Investments (the parent company of the Autoleague motor vehicle group), with $3.4 billion in sales across 66 dealerships in WA, Queensland and Victoria.
The remaining top 10 positions are held by underground mining contractor Byrnecut ($3.1 billion), employment and disability services provider APM Human Services International ($2.6 billion), diversified investment group Perron Group ($2.4 billion), health insurer HBF ($2.3 billion) and the Forrest family's investment vehicle Tattarang ($2.2 billion).
Across the full list, mining and resources accounts for the largest share of revenue, followed by property and construction, agribusiness and food, and health and aged care.
The publication also includes a separate analysis of WA's family office sector, identifying 109 dedicated investment vehicles managing wealth that runs into the hundreds of billions of dollars.
Data was compiled using a combination of ASIC lodgements, ATO corporate tax transparency reports, industry benchmarking and direct company engagement.
Business News’ inaugural Top 100 Private Businesses publication is available from Monday.
