Top 10 Biggest Companies in Australia 2025

Australia’s corporate landscape is controlled by a few big players that not only drive the national economy but also the investment, property and digital-service ecosystems you and your readers interact with every day. Knowing who these “big-10” companies are is a useful filter for your verticals—whether it’s tracking institutional investment flows in property markets, analysing capital allocation in tech/IT or monitoring large-cap exposure in portfolio strategies.

Why Do the “biggest Companies” Matter?

• The total market cap of all listed domestic companies in Australia was around US $1.737 trillion in 2024.
• The biggest companies—especially the banks and resources companies—account for a disproportionate share of the national market-cap and therefore influence index behaviour, investor sentiment and capital availability for smaller companies (including in IT/web-services or property infrastructure).
• For property and investment themes: The big companies set the tone for credit availability, dividend flows, superannuation fund allocations and downstream supplier ecosystems (contractors, PropTech, digital agencies).
• For your web-design/IT vertical: Many of Australia’s biggest companies are big clients for digital transformation, venture funding and outsourcing—so knowing who they are helps you position your service offerings accordingly.

Snapshot of the Top-10 Largest Companies in Australia (by market cap)

Here are some of the largest companies in Australia today, giving a flavour of sectors and scale:

Top 10 Biggest Companies in Australia 2025

1. Commonwealth Bank of Australia

Commonwealth Bank of Australia (CBA) is Australia’s largest publicly-listed company – and for good reason. Here’s why, followed by the latest numbers.

Why is CBA the Best?

• Scale and market share: CBA has a big chunk of Australia’s mortgage and deposit businesses, making it the leader in retail and business banking. For example, it writes around a quarter of Australia’s ~$2.2 trillion mortgage market.
• Strong performance: CBA has delivered strong net profit after tax (NPAT) and high payout ratios through economic ups and downs – it’s operationally resilient. For FY 2024 CBA reported a statutory NPAT of $9,394 million (down ~6% year-on-year) and a fully-franked dividend of $4.65 per share.
• Disciplined cost-income ratios: With total operating income of $27,174 million in FY 2024, CBA is generating strong revenue.
• Leading in digital banking and customer experience: By investing in technology and customer platforms, CBA has built customer loyalty and lower relative cost structures which supports margins and retention.
• Resilience through macro headwinds: Even when the economy is tough, CBA delivers returns – it shows it can manage credit risk and maintain margins. For example, it reported a FY2025 cash NPAT of ~$10.252 billion.

Selected Financial Metrics

Below is a summary table of recent key financials for CBA:

Why These Numbers Matter

• With operating income over $27 billion, CBA can generate big revenue across many banking products – a hallmark of a top-tier bank.
• A net profit of ~$9.4 billion when profit fell shows the bank’s franchise strength and ability to absorb economic shocks and still deliver returns.
• EPS and dividend levels mean shareholders are being rewarded consistently – the dividend of $4.65 per share in FY 2024 is fully franked, so it’s attractive to many investors.
• The diversified business (retail, business, institutional banking, wealth, insurance) reduces reliance on any one segment – adds to stability and reinforces its “powerhouse” status.
• And its leadership in technology and customer-centric banking gives it a competitive edge in a market where digital experience matters.

CBA’s scale, profitability, operations, shareholder returns and digital leadership makes it Australia’s number one bank and the benchmark for “biggest company”. For your finance/investing audience, CBA is a case study on how a financial services business builds scale, maintains margins, diversifies across products and returns capital to shareholders.

2. BHP Group

BHP Group (a name more commonly known as BHP) has earned a place at the very top of Australia’s business elite through a combination of its enormous scale in natural resources, a global footprint that stretches far and wide, and an unwavering commitment to operating with discipline.

It stands out for a number of very compelling reasons, each of which helps to explain why we’d describe it as “the Global Mining Titan Fueling Australia’s Resource Economy”

Why is BHP the Best in Class

• The sheer scale and reach of its global operations sets it apart: BHP operates – amongst other things – iron ore, copper, coal, potash and other resource assets all around the world, which gives it a really broad exposure to key commodity swings and shifts.
• Top-notch operational performance: In FY 2024 BHP brought in an operating profit of US $17.5 billion – a truly impressive sum.
• A sustained focus on growth in key commodities : With for example copper volumes up by 9% in FY 2024 – the second year in a row to see a rise.
• Leading the charge on cost : BHP’s Western Australia Iron Ore (WAIO) operations are the lowest-cost iron ore producers in the world, which is no mean feat.
• Delivering strong returns for its shareholders : In FY 2024 it paid out a final dividend of 74 cents per share, with a full-year payout ratio of around 53%
• Future-proofing its portfolio : BHP is ploughing a lot of money into investing in growth for copper and potash – two of the key commodities that will drive the shift to cleaner energy and fertilisers.

Selected Financial Metrics

Below is a summary of some of BHP’s recent key financials (for year ended 30 June 2024).

Why These Figures Matter

• Revenue of ~US $55.65 billion confirms that BHP operates at a truly massive scale, putting it amongst the major resource companies in Australia – and the world.
• Profit from operations and underlying profit show that BHP doesn’t just rely on its size – it’s also executing really well, sustaining its margins even in a highly volatile commodity market.
• The dividend of US $1.46 per share and 53 % payout ratio show that BHP is striking a good balance between reinvesting and returning to shareholders – a hallmark of a top-class mining company.
• Its cost leadership (for example the lowest-cost iron ore production) and sustained growth in high-demand commodities (like copper) give it structural advantages, not just cyclical benefits.
• With global demand for minerals like copper, potash and iron ore expected to stay strong (especially as the world builds more infrastructure, switches to cleaner energy and urbanises), BHP’s portfolio positions it well for the long term – which all adds to its “titan” status.

To cut a long story short, BHP’s combination of size, global diversified commodity exposure, cost-leadership, consistent operational performance and shareholder return make it a clear leader amongst Australia’s biggest companies.

For finance and investing professionals, BHP serves as a prime example of how a resources-based company can dominate both at home and abroad – and also adapt for future growth beyond traditional commodity cycles.

3. CSL Limited

CSL Limited stands out through its focus on cutting-edge therapies, global reach, strong growth and innovation in biotechnology.

It’s one of Australia’s top companies not just for size but for its position in the global healthcare-biotech sector.

Why is CSL Best in Class?

• Innovation-backed global business model: CSL’s businesses cover lifesaving therapies (CSL Behring), vaccines (CSL Seqirus) and iron-deficiency/nephrology treatments (CSL Vifor) – giving it broad exposure across major healthcare segments.
• Strong revenue and profit growth: For the 12 months ended 30 June 2024, CSL reported total operating revenue of US $14.80 billion, up ~11% from the prior year.
• High net profit after tax (NPAT) and earnings per share (EPS): NPAT was US $2.64 billion in FY2024, with basic EPS of US $5.47 (up from US $4.55 in the prior year).
• Good shareholder returns: Full-year dividend was US $2.64 per share for FY2024 (final US$1.45 per share) – a decent payout for shareholders.
• Leadership in high-demand medical portfolios: For example, immunoglobulin (Ig) product sales grew ~20% in FY2024, driven by strong patient demand globally.
• Global footprint and resilience: CSL operates in over 100 countries, employs over 32 000 people and is headquartered in Melbourne but serves global markets.

Selected Financial Metrics

Here is a table summarising key metrics for FY2024:

Why These Numbers Matter

• The 11% revenue growth shows CSL can grow in competitive biotech markets – impressive given the regulatory, development-cycle and R&D-intensity headwinds in this sector.
• NPAT of US $2.64 billion and EPS of US $5.47 means the growth is not just top-line, but profitable and for shareholders.
• The dividend of US $2.64 per share means the company is committed to paying out to shareholders – which for a biotech company (often re-investing heavily into R&D) is a good balance between growth and return.
• Growth in key product lines (e.g. immunoglobulin sales up ~20%) shows CSL is executing on its innovation pipeline, meeting patient demand and strengthening its market position.* Global footprint and leadership in plasma-derived therapies, vaccines and specialty pharma gives it a structural moat — no single geography or product to rely on.

In summary, CSL Limited’s innovation-backed business, diversified therapeutics, global reach, profit growth and shareholder returns makes it one of the best Australian companies.

For your finance/investing audience, CSL is a great example of how a healthcare/biotech company can go global, grow profitably, invest in growth and deliver to shareholders — one of the top Australian large caps.

4. National Australia Bank

National Australia Bank (NAB) is a major player in Australia’s commercial and retail banking landscape — serving millions of customers from small businesses to large corporations.

It stands out for several reasons, hence the tag “the Trusted Financial Partner Driving Business Growth.”

Why is NAB the Best in Class?

• Widespread business banking footprint: NAB lent $48 billion to businesses in FY 2024, backing growth and showing its commitment to business & private banking.
• Resilience in tough times: NAB reported statutory net profit after tax of $6.96 billion in FY 2024, down 6.1 % on the prior year — so it’s still profitable despite the headwinds.
• Investing in growth areas: NAB grew deposits in its Business & Private Banking division by 7% in the year, so it’s focused on scaling this segment.
• Strong regulatory and capital position: NAB had a CET1 capital ratio of 12.35% at year-end which is a solid capital base and prudent risk management.
• Diversified offering: As one of Australia’s “Big Four” banks, NAB offers retail, business, institutional banking and wealth services — so it’s across the customer spectrum and not reliant on one segment.

Selected Financial Metrics

Here is a summary of the key financials for FY 2024:

Why These Numbers Matter

• A revenue of ~$20 billion means NAB is a big business — essential for any bank that wants to be a top-tier player.
• Net profit of nearly $7 billion (even down from the prior year) means the bank is still a major profit-maker — important in the Australian banking landscape.* The cash earnings and the dividend being maintained shows NAB is balancing growth, profit and shareholder returns — not sacrificing one for the other.
• The 85 cents per share (fully franked) dividend means shareholders are getting a decent return — which is a key feature of a big, trusted financial institution.
• The growth in business banking deposits and loans shows NAB is strategically strong in supporting corporate clients and is a partner in business growth not just a retail lender.

In summary, NAB’s wide footprint in commercial and retail banking, strong capital, scale and tangible support for business growth makes it a big player in the Australian financial landscape.

For your finance/investing audience, NAB is a great example of how a diversified bank can support everyday consumers and business clients while delivering shareholder returns and managing risk — so it’s a good one to include among Australia’s largest companies.

5. Westpac Banking Corporation

Westpac Banking Corporation (Westpac) combines a rich history and a digital future — one of Australia’s biggest and most robust financial institutions.

Founded in 1817 (as the Bank of New South Wales) and merged into Westpac in 1982, the bank has more than two centuries of banking experience.

Why Westpac is Best in Class?

• Legacy and transformation: As Australia’s oldest bank, Westpac uses deep market knowledge, while investing heavily in digital banking platforms and customer service to stay ahead.
• Strong financials and scale: FY 2024 revenue of $21.76 billion.
• Profitability endures: Net profit after tax (statutory) FY 2024 $6.99 billion, down 3% on FY 2023 — a tough environment.

• And Westpac announced a full year ordinary dividend of $1.51 per share (fully franked).
• Digital and customer experience focus: Improving customer service, growing consumer and business banking, and maintaining a strong capital base — gives Westpac strategic strength in the market.

Selected Financial Metrics

• $2.009 EPS is per-share profit, useful for investors to value on a per-share basis.

For your finance/investing audience, Westpac is a strong case: a big bank that bridges traditional and modern — a part of the Australian corporate landscape and one of the biggest companies in Australia.

6. Australia and New Zealand Banking Group

The ANZ Banking Group – a standout in Australia’s major banking landscape – holds a singular position, blending regional presence with a strategic banking product reach that spans the country, New Zealand, and beyond.

It earns its title – “Regional Banking Leader with Trans-Tasman Strength” – by cleverly combining geographic reach, a diverse range of services, and robust institutional operations.

Why ANZ sets itself apart

• Its dual-country footprint has ANZ serving both Australian and New Zealand markets, giving it access to trade flows, institutional banking and corporate lending right across the Tasman.
• ANZ’s revenue mix is highly diversified across retail, commercial and institutional banking – Australia Retail makes up about 29%, Australia Commercial 17%, and Institutional a healthy 34% as of FY 2024.
• A look back at ANZ’s recent full-year performance for the year ended September 2024 shows a statutory profit after tax of $6,535 million – a bit down 8% on the previous year – which still highlights both the scale and resilience of the business in a competitive environment.
• ANZ’s board has shown a strong commitment to shareholder returns by declaring a final dividend of $0.83 per share (70% franked) for FY 2024 – which brings the full-year dividend to approximately $1.66 per share.
• ANZ has also been investing heavily in its digital banking platform (think “ANZ Plus”) which has grown to around 700,000 customers and $14 billion in deposits in the half-year period.
• ANZ’s capital and prudential metrics remain strong with a Common Equity Tier 1 (CET1) ratio of 12.2% for FY 2024 – supporting its status as a major regulated banking group.

Selected Financial Metrics

Why these numbers are worth paying attention to

• When revenue tops $20 billion, as it does at ANZ, you’ve got a real contender on your hands – and it solidifies the bank’s position among the largest in Australia and the region.
• Even though profit was down a bit year-on-year, a net profit after tax of $6.535 billion still shows ANZ is able to generate significant earnings despite all the challenges it faces – and that’s a key mark of a top-performing company.
• EPS of around $2.24 per share gives investors a clear view of the bank’s profitability, enabling them to compare how it’s performing against its peers and make informed decisions about value.
• The fact that ANZ is still able to pay out a full-year dividend of $1.66 per share despite profit pressure shows that the bank remains committed to returning cash to shareholders – which is exactly what income-focused investors are looking for.
• The fact that ANZ is investing so heavily in digital platforms (that’s 700,000 customers and $14 billion in deposits for you) suggests a company with real future ambitions – not just a bank that’s stuck in the past.
• A strong capital ratio (12.2% CET1) is essential for any bank to worry about, but ANZ is able to tick this box with ease – and that’s another tick in the box for its status as a reliable major bank.

In a nutshell, ANZ’s combination of a strong geographical presence (Australia and New Zealand), a diversified range of services (retail, commercial, institutional), scale, meaningful profitability, and shareholder returns make it a standout in Australia’s largest companies.
