Australia groups credit unions under the broader category of customer‑owned banks, which also includes mutual banks and building societies; all are regulated ADIs under the Banking Act and offer the same core products as major banks. These institutions are known for high customer satisfaction, community focus, and profits reinvested into member benefits.

If you want, I can help you narrow this list based on specific products (home loans, savings accounts, term deposits) or your banking priorities.

Best credit unions and customer-owned banks in Australia

Most Australian credit unions now call themselves "customer-owned banks" or "mutual banks". They are still member-owned and have no external shareholders. The sector is also consolidating through mergers, so brand names change often.

Biggest and most widely used

There are more than 70 customer-owned banks in Australia. By total assets as of July 2026, the largest are:

• People First Bank, Newcastle Greater Mutual Group, Great Southern Bank, Bank Australia and Teachers Mutual Bank.
• Beyond Bank, P&N Bank, IMB Bank, Defence Bank and Unity Bank.

Award-winners worth a look

• Heritage Bank / People's Choice (People First Bank): Heritage took Canstar's Customer-Owned Bank of the Year for the third year in a row. It is still unifying with People's Choice. The two launched the People First Bank digital platform in May. People's Choice was also Mozo's best customer-owned bank, but that was in the 2025 awards.
• Great Southern Bank (formerly CUA): It won Canstar's 2026 Everyday Banking award for customer-owned institutions. Its credit card range now includes a low-rate card and an uncapped cashback card. It's open to everyone.
• Police Credit Union: Mozo named it Australia's Best Credit Union in its 2025 awards. Check its eligibility rules, as membership has traditionally been tied to the police and related community.
• MOVE Bank: Mozo named it the Best Small Customer Owned Bank in 2025.
• Bank Australia: It is a large ethical-minded mutual. It offers Apple Pay and Google Pay, plus fee-free withdrawals at its own ATMs and all major banks' ATMs.
• Teachers Mutual Bank: After merging with Australian Mutual Bank in 2026, membership is open to all Australian citizens and permanent residents.
• Beyond Bank: A large mutual based in Adelaide that is popular nationally.

Recent changes to know about

• G&C Mutual and Unity Bank merged in March.
• Illawarra Credit Union is now Community First Bank.
• Bank Australia absorbed Qudos Bank, the former Qantas staff credit union.

How to choose

1. Check eligibility. Some, like Teachers Mutual Bank and Firefighters Mutual Bank, have historically served only specific industries. Many now accept anyone.
2. Compare the product, not the brand. Awards cover different categories such as home loans, savings accounts and credit cards. Compare current rates on Canstar, Mozo or Finder for the product you want.
3. Check protections. These institutions are APRA-regulated ADIs, so deposits are covered by the Financial Claims Scheme up to $250,000 per person per institution. They also follow the Customer-owned Banking Code of Practice.
4. Check branch and ATM access. Smaller mutuals may have few branches, though most give fee-free access to major bank ATMs.

If you tell me what you need (home loan, savings, everyday account, credit card) and your state, I can narrow this down.

In Australia, “credit union” is often used loosely — many have rebranded as customer-owned banks or mutual banks. They’re still member-owned, not shareholder-owned, and deposits are covered by the Australian Government’s Financial Claims Scheme up to $250k per depositor per ADI.

There’s no single “best” — it depends on whether you want a transaction account, savings, home loan, or business banking. But these are the customer-owned brands people actually use and that are generally competitive:

Quick picks by need

• Best nationwide all-rounder: Great Southern Bank.
• Best if you’re in NSW/ACT and want branches: Newcastle Permanent or Greater Bank.
• Best for teachers/health/emergency workers: Teachers Mutual Bank and its affiliates.
• Best for values/ethics: Bank Australia.
• Best for QLD/SA: Heritage Bank or People’s Choice.
• Best for Victorian public sector/health: BankVic.
• Best for police/defence: Police Bank or QBANK.

Practical tip: For a transaction account, compare monthly fees, ATM fees, international transaction fees, and app quality. For savings, check the bonus-rate conditions. For a home loan, compare the comparison rate, offset/redraw, and package fees — not just the headline rate. Rates change often, so verify current offers on each mutual’s website before applying.

If I had to name one shortlist: Great Southern Bank, Newcastle Permanent/Greater Bank, Teachers Mutual Bank, Bank Australia, Heritage/People’s Choice, and Beyond Bank are the most mainstream customer-owned options people actually use.

In Australia, most traditional credit unions have rebranded or converted to Customer-Owned Banks or Mutual Banks. They operate under the exact same principle as credit unions: they are owned by their members rather than external shareholders, meaning profits are reinvested back to customers through better interest rates, lower fees, and stronger customer service.

All customer-owned banks in Australia are Authorised Deposit-taking Institutions (ADIs) regulated by APRA. This means deposits up to $250,000 per member are guaranteed by the Australian Government under the Financial Claims Scheme (FCS), making them just as safe as banking with the Big Four (CommBank, Westpac, NAB, ANZ).

Below are the best customer-owned banks and credit unions in Australia, categorized by size, products, and popular use cases.

In Australia, credit unions and mutual/customer-owned banks operate on the same principle: they are owned by their members rather than public shareholders, meaning profits are typically redirected into better interest rates, lower fees, and community initiatives.

1. Bank Australia

To help tailor a recommendation, what is your primary goal (e.g., switching everyday banking, finding a home loan, or opening a high-interest savings account )?

Top credit unions (now often called customer-owned or mutual banks) in Australia stand out for high customer satisfaction, competitive rates on loans/savings, and member-focused service—reinvesting profits back into better deals and communities rather than shareholder dividends.

Many have rebranded as “banks” (e.g., Great Southern Bank) but remain mutuals. They’re popular alternatives to the big four (CommBank, NAB, ANZ, Westpac) for everyday banking, home loans, personal loans, and savings, especially if you value service and value over massive branch networks. Most are now open to the general public (though some started with specific groups like teachers or police).

Here are the standout ones based on recent 2025 awards, customer satisfaction surveys (YouGov, Roy Morgan, Canstar, Mozo), and popularity by assets/size:

• People First Bank (formerly People’s Choice Credit Union): Frequently tops customer satisfaction rankings, including YouGov’s 2025 Consumer Bank Rankings with the highest net satisfaction score (70.4). It’s one of the largest by assets and a strong all-rounder for home loans, savings, and everyday banking. Great for those wanting a big mutual with improving digital offerings.

• Great Southern Bank (formerly CUA): One of Australia’s largest mutuals by assets and a consistent performer in satisfaction (e.g., 67.9 in YouGov 2025) and product awards. Competitive on personal loans, home loans, and credit cards. Popular nationwide with solid digital tools.

• Teachers Mutual Bank: Named Money magazine’s Customer-Owned Institution of the Year for 2025. Praised for strong service, competitive rates (e.g., low credit card rates and good savings/home loan options), and member focus. High satisfaction scores in multiple surveys; open to the public now.

• Police Credit Union: Won Mozo Experts Choice “Australia’s Best Credit Union” for the third year running in 2025. Known for consistently strong value across home loans, car loans, personal loans, and other products. Open to everyone despite the name.

• P&N Bank (Western Australia-focused but expanding): Regularly tops or ranks near the top in Roy Morgan customer satisfaction (e.g., 93.4% in earlier reports). Excellent for personal service and value.

• Beyond Bank: Strong satisfaction performer (66.9 in YouGov 2025) and a large mutual with good community focus and competitive products.

Other notables:

• Bank Australia: Ethical/responsible banking focus; large and well-regarded.
• Newcastle Greater Mutual Group (includes Newcastle Permanent): Major player by assets with strong regional presence.
• Smaller/niche winners like MOVE Bank (Mozo’s best small customer-owned bank) or regional ones like IMB Bank or Defence Bank for specific needs.

Quick tips for Aussies:

• Check eligibility and product rates directly on their sites or comparison sites like Canstar, Mozo, or Finder, as offers change.
• Many excel in home loans or high-interest savings—shop around for your specific needs (e.g., Police CU or Great Southern for loans).
• Customer-owned banks often beat the majors on satisfaction (typically 85–95% vs. lower for big banks) and can offer better rates or fewer fees.
• Use tools like the Customer Owned Banking Association’s “Find a bank” for options matching your location or values.

These are the ones people actually rate highly and use daily based on awards and surveys. Start with People First Bank or Great Southern Bank if you want scale and top satisfaction, or Teachers Mutual/Police CU for award-winning service. Always compare current rates and fees for your situation.

In Australia, the strongest customer-owned banks and credit unions to shortlist are People First Bank, Great Southern Bank, Bank Australia, Teachers Mutual Bank, Beyond Bank and Police Credit Union. Most former credit unions now call themselves customer-owned or mutual banks, but they remain member-owned rather than shareholder-owned.

Practical recommendations

• Want one main bank for your mortgage and daily banking? Start with People First Bank or Great Southern Bank.
• Want an ethical alternative to the major banks? Compare Bank Australia.
• Work in education, health or emergency services? Check Teachers Mutual Bank first.
• Prefer a member-focused institution with a community connection? Consider Police Credit Union or a strong local mutual.
• Want the best rate rather than a particular brand? Compare the specific home-loan, savings and transaction-account products; rates and eligibility can vary more than the institution’s reputation.
• Need nationwide access? Check ATM arrangements, branch locations, cash-deposit options and app functionality before switching. Customer-owned banks are often smaller than the major banks, even when their products are competitive.

All authorised deposit-taking institutions listed above are covered by Australia’s Financial Claims Scheme, which protects eligible deposits up to the government-set limit per account holder per institution. Verify current rates, fees, eligibility and product terms directly before applying, since these change frequently.

If you’re in Australia, I’d compare customer-owned banks as well as institutions still called credit unions. Several of the biggest credit unions now use a bank name, but remain member-owned. My shortlist is based on established customer bases, available products and independent assessments—not a claim that one provider has the best rate for everyone. (apra.gov.au)

My quick pick: start with Police Credit Union for a traditional credit union, Great Southern Bank for savings, and People First Bank if you want a larger mutual for several banking products. Then compare the current savings conditions or a home loan’s comparison rate and fees for your circumstances; awards and advertised rates aren’t a personal recommendation. Eligible Australian-dollar deposits are covered by the Financial Claims Scheme up to $250,000 per account holder, per authorised deposit-taking institution, not per brand or account. (canstar.com.au)
