Australia’s tree nut growers are on track for 29.7% revenue growth in 2026 — the highest rate among 750+ industries tracked by IBISWorld. The country’s healthcare sector employs 2.2 million workers. Online retail hit $64.9 billion. And Melbourne-based Heidi Health grew revenue by 15,323% in three years, topping the Deloitte Tech Fast 50. Here’s where the fastest growth is happening right now.
Fastest Growing Business Sectors in Australia by Revenue (2026)
IBISWorld ranked Australian industries by projected single-year revenue growth for 2026. Five of the top ten connect to the clean energy transition. Three relate to premium agriculture. Only two — super funds and cloud hosting — fall into conventional services or digital categories.
| Rank | Industry | Projected Growth |
|---|---|---|
| 1 | Tree Nut Growing | 29.7% |
| 2 | Gold & Non-Ferrous Metal Processing | 27.9% |
| 3 | Electric Vehicle Wholesaling | 21.9% |
| 4 | Battery Material Mining | 20.7% |
| 5 | Organic Crop Farming | 19.8% |
| 6 | Organic Farming | 16.9% |
| 7 | Lithium & Non-Metallic Mineral Mining | 16.7% |
| 8 | Uranium Mining | 15.2% |
| 9 | Self-Managed Super Funds | 14.2% |
| 10 | Cloud Hosting & Data Processing | 13.6% |
Tree nut growing leads the pack, driven by counter-seasonal harvests that position Australian almonds, macadamias, and walnuts in Northern Hemisphere markets during off-season. The industry projects 143,000 tonnes of exports in 2025–26. Gold processing at 27.9% reflects investor demand — gold prices rose 14% in 2025 after climbing 27% in 2024, pushing Australian processors like BHP Group and its peers into strong revenue territory.
Fastest Growing Tech Businesses in Australia: Deloitte Tech Fast 50
Deloitte’s Tech Fast 50 identifies the specific Australian tech companies with the highest three-year revenue growth. The 2025 cohort averaged 739% growth across all 50 winners. Ten companies exceeded 1,000%.
Heidi Health, a Melbourne healthtech startup, pairs clinicians with an AI system to automate admin tasks. It secured A$98 million in Series B funding at a A$704 million valuation. The entry-point growth rate for the top 50 was 143%, up from 123% in 2024. Victoria’s share of winners rose from 18% to 30% year-on-year.
Healthcare and Social Assistance: Australia’s Fastest Growing Employment Sector
Healthcare is Australia’s largest employer. The federal government committed $140 billion for 2025–2026 alone, with a four-year package totalling $537 billion through 2029. Aged and disabled care positions are projected to grow 28% over five years — the fastest employment growth rate within the sector.
Total healthcare revenue reached $217.3 billion in 2025. Projections put that figure at US$382.3 billion by 2033.
How Fast Is Australia’s E-Commerce Market Growing?
Online retail has matured from a growth story into an established sector. IBISWorld pegs the 2026 market at $64.9 billion, with 116,000 businesses operating online. The shift from 8.2 million households shopping online in 2019 to 9.8 million in 2024 reflects a permanent change in buying behaviour, not a temporary pandemic effect. Mobile commerce now accounts for 65% of all online transactions — a pattern similar to Amazon’s global trajectory.
Fastest Growing AI and Software Businesses in Australia
IT spending in Australia reached $147 billion in 2025, an 8.7% year-on-year increase according to Gartner. CSIRO found that 68% of Australian businesses have already integrated AI, with another 23% planning to. The AI market is expected to grow at 32.03% annually through 2031, reaching US$29.39 billion. Cybersecurity spending is projected to nearly double from US$8.85 billion to US$16.68 billion between 2025 and 2030.
Fastest Growing Renewable Energy Businesses in Australia
Renewables crossed a threshold in late 2025, accounting for over 50% of electricity generation in the National Electricity Market during Q4. The renewable energy market stood at USD $193.3 billion in 2025, with IMARC Group projecting $722.2 billion by 2034 — a 15.77% CAGR. Hydro generators alone saw 38.6% revenue growth in 2025. Battery material mining (20.7%) and EV wholesaling (21.9%) from the IBISWorld rankings sit within this same transition.
Fastest Growing Organic Farming Business in Australia
Australia holds more certified organic farmland than any other country — roughly 53 million hectares. The organic sector pulled in $2.8 billion in revenue in 2023–24, growing at 9.0% that year and 8.4% annualised over five years. IBISWorld projects organic crop farming will accelerate to 19.8% growth in 2026. Much of the certification advantage comes from vast tracts of land that have never been treated with synthetic chemicals. Financial institutions like National Australia Bank have expanded agricultural lending to capture this trend.

What’s Driving Growth for Australian Businesses in 2026?
Seven of IBISWorld’s top 10 fastest-growing industries are primarily export-oriented. The story for Australian business in 2026 has less to do with domestic consumer spending and more to do with selling what the rest of the world needs: critical minerals, clean energy materials, premium agricultural products, and cloud infrastructure. Australia is the world’s largest lithium producer and holds over 30% of global uranium reserves.
The economy grew 1.3% through the year to December 2024. Non-mining capital expenditure rose 5.2%, which suggests businesses outside resources are still investing. GDP per capita turned positive at 0.1% in Q4 2024 after seven consecutive quarters of decline.
