Great Southern Bank

Short answer

In Australia, the “best credit unions” are mostly customer-owned banks / mutual banks now — many former credit unions have rebranded as banks while staying member-owned. As of September 2026, I’d shortlist these:

1. People First Bank / Heritage Bank – best all-round, largest-scale mutual
2. Great Southern Bank – best mainstream former credit union for everyday banking + home loans
3. Bank Australia – best ethical/customer-owned option; strong for credit cards and green home loans
4. Teachers Mutual Bank group – best for teachers, health, university and emergency-services workers
5. Greater Bank / Newcastle Permanent — NGM Group – best NSW/regional scale option
6. Beyond Bank – best community/B Corp-style all-rounder
7. P&N Bank / BCU Bank – best if you’re in WA, NSW or Queensland and value customer satisfaction
8. Police Credit Union – best “literal credit union” pick, especially if you want a smaller credit-union brand

Customer-owned banking is a meaningful sector in Australia: COBA says customer-owned banks serve 5.4M+ Australians, across 47 member institutions, with about $200B in combined assets under management. (customerownedbanking.asn.au)

Top picks Australians actually use

Best product matches

Best all-in-one customer-owned bank:
Go with People First Bank / Heritage Bank if you want a large mutual with a broad product range — everyday accounts, savings, home loans, credit cards and personal lending — and you prefer a bigger institution without going to the Big Four.

Best former credit union for normal daily banking:
Choose Great Southern Bank if you want a recognisable former credit union with national scale, standard everyday banking, savings accounts and home loans.

Best ethical bank:
Choose Bank Australia if values matter — fossil-fuel screening, ethical positioning, green lending and a strong customer-owned brand. It’s also one of the better customer-owned options to check for credit cards.

Best for teachers / nurses / ambos / firies / uni staff:
Choose Teachers Mutual Bank group — including UniBank, Health Professionals Bank and Firefighters Mutual Bank — if you fit one of those communities and want banking designed around professional cohorts.

Best NSW regional mutual:
Choose Greater Bank or Newcastle Permanent if you live in NSW, especially the Hunter, Newcastle, Central Coast or regional areas, and want a customer-owned bank with real scale.

Best community-first alternative:
Choose Beyond Bank if you want a customer-owned bank with a social-impact/community flavour and decent all-round banking.

Best WA option:
Look at P&N Bank if you’re in WA. If you’re in NSW or Queensland, also compare BCU Bank, which is in the same P&N Group.

Best literal credit union:
Look at Police Credit Union, especially if you’re comparing home loans, car loans or personal loans from smaller mutuals.

Quick safety check

Most of these institutions are APRA-authorised deposit-taking institutions. Under Australia’s Financial Claims Scheme, eligible deposits are protected up to $250,000 per account holder, per ADI — but watch merged groups and multiple trading names, because the limit applies per ADI licence, not per brand name. (apra.gov.au)

Rates, bonus-interest rules and credit-card perks change often, so before opening anything, compare the current interest rate, account fees, bonus conditions, offset/redraw terms, international transaction fees and branch/ATM access. My practical shortlist would be: People First Bank, Great Southern Bank, Bank Australia, Teachers Mutual Bank and Greater/Newcastle Permanent.

Here's the current landscape for credit unions in Australia. Quick note: most Australian credit unions have rebranded as "mutual banks" or "customer-owned banks" over the past decade due to regulatory changes, but they operate on the same not-for-profit, member-owned model — profits go back to members via better rates and lower fees rather than shareholders.

Most Popular / Widely Used Options

Great Southern Bank (formerly CUA) – One of the largest customer-owned banks in the country, popular for home loans and everyday banking, with a strong branch and digital presence.

People First Bank – Formed from the 2023 merger of Heritage Bank and People's Choice Credit Union, making it Australia's largest mutual bank by member numbers. Strong in home loans, car loans, and everyday accounts.

Newcastle Permanent – One of the biggest building societies/mutuals, especially popular in NSW for home loans and term deposits.

Teachers Mutual Bank Group – Actually a group of five brands (Teachers Mutual Bank, UniBank, Firefighters Mutual Bank, Health Professionals Bank, and Hiver) targeting specific professions with tailored products and competitive home loan rates.

Beyond Bank – One of the larger mutuals, known for ethical banking credentials and solid savings/home loan products, strong presence in SA and expanding nationally.

Bank Australia – Popular with environmentally and ethically conscious customers; well known for not investing in fossil fuels, weapons, or gambling, and for carbon-neutral operations.

RACQ Bank / RACV Bank – Popular in Queensland and Vict

In Australia, the traditional "credit union" landscape has evolved. While some pure credit unions still exist, most of the country's top-tier, member-owned institutions have rebranded or merged into "mutual banks" or "customer-owned banks".

They operate on the exact same customer-first model as credit unions—where profits are reinvested into better rates, lower fees, and community programs rather than paid to external shareholders—but they carry the "bank" title and have the scale to offer modern digital banking features. Additionally, like the "Big Four" banks, all customer-owned banks are protected by the Australian Government’s Financial Claims Scheme, meaning your deposits are guaranteed up to $250,000.

The best customer-owned institutions and products in Australia include several standout brands:

1. Bank Australia (Best for Ethical Banking & Digital)

If you want to move away from the big banks for environmental or ethical reasons, Bank Australia is the premier choice.

They recently expanded their footprint even further by merging with Qudos Bank.

4. People First Bank (Best for Home Loans & East Coast Presence)

People First Bank is a newly established powerhouse formed by the massive merger of Heritage Bank and People’s Choice Credit Union. With over 730,000 members and a history spanning 150 years, they have major physical presence across Queensland, South Australia, Victoria, and NSW.

If you want the best credit unions in Australia that people actually use, the safest shortlist is Great Southern Bank, People’s Choice Credit Union, Credit Union SA, Police Credit Union, and Bank Australia. For home loans, everyday banking, and savings, Great Southern Bank and Bank Australia are especially common picks, while Police Credit Union stands out for loan products.

A practical shortlist for Australians would be:

• Great Southern Bank — the most consistently recommended brand in the search results and a major customer-owned institution.
• People’s Choice Credit Union — one of the largest customer-owned lenders by assets and deposits in the provided results.
• Police Credit Union — highlighted as Australia’s Best Credit Union in Mozo’s awards, with recognition for home loans, personal loans, and car loans.
• Bank Australia — repeatedly recommended as a strong customer-owned option and widely used in consumer discussions.
• Credit Union SA — a strong regional brand that also appears in the top recommendations.

If you want the “top brands or products” people actually use, I’d focus on these product types:

• Home loans — Great Southern Bank, Police Credit Union, People’s Choice Credit Union.
• Everyday transaction accounts — Great Southern Bank, Bank Australia, People’s Choice Credit Union.
• Savings accounts / term deposits — Bank Australia and Great Southern Bank are commonly shortlisted among customer-owned banks.
• Personal loans and car loans — Police Credit Union is specifically called out for these.

A quick note on naming: in Australia, many “credit unions” have merged or rebranded into customer-owned banks, so the best-known brands are sometimes not still using the exact “credit union” label.

In Australia, the term "credit union" has largely evolved into customer-owned banks, mutual banks, and building societies. They are owned by their members, not shareholders, which usually means lower fees, fairer rates, and a focus on customer value.

Here are the top customer-owned brands Australians actually use, plus the specific products that stand out:

1. People’s Choice — Australia’s largest credit union

People’s Choice was originally a credit union and, after merging with Heritage Bank, is now the largest customer-owned bank in Australia.

• Best products:
  • Complete Access / everyday transaction account – no monthly fees
  • People’s Choice Savings Account – competitive bonus interest
  • Low-rate credit cards
• Why people use it: huge ATM network, solid branch presence in SA, QLD, NSW and VIC, decent mobile app, and genuine customer-owned ethos.

2. Great Southern Bank (formerly CUA)

CUA rebranded as Great Southern Bank but it’s still one of the biggest mutual banks in Australia.

• Best products:
  • Everyday Options account – no monthly fees, easy access
  • NetBank Saver – long-running online savings account that consistently pays a solid rate
  • Home loans – well rated for refinancing and first home buyers
• Why people use it: nationwide presence, strong reputation, and product simplicity.

3. Beyond Bank Australia

A genuine credit union that acts like a modern bank, originally from public service and community roots.

• Best products:
  • Beyond Bank Freedom Account – no monthly fees, fee-free ATMs

A customer-owned bank with a very strong environmental and social focus. It was originally a credit union too.

• Best products:
  • Clean Money Everyday Account
  • Real Savings Account

5. IMB Bank

IMB is a mutual building society, but it acts like a credit union, based mainly in NSW/ACT/VIC.

• Best products:
  • IMB Reward Saver – one of the highest ongoing bonus saver rates around

Top credit unions (or customer-owned banks/mutuals) in Australia that people commonly use and rate highly include Teachers Mutual Bank, People First Bank (formerly People’s Choice), Great Southern Bank (formerly CUA), Police Credit Union, and Beyond Bank.

These stand out in recent 2025 awards and customer satisfaction surveys for service, value, competitive rates on loans/savings/credit cards, and member focus (profits go back to members rather than shareholders). Many Aussies use them as alternatives to the big four banks for better personal service, competitive home loans, savings rates, or everyday banking, especially if they qualify for eligibility (e.g., profession or location) or value the mutual model.

Top Recommendations

Here are standout options based on awards, satisfaction data, size/popularity, and real-world usage:

• Teachers Mutual Bank: Named Money magazine’s Customer-Owned Institution of the Year for 2025. It earns praise for straightforward products, excellent member service, competitive rates (e.g., credit cards from 7.90%, home loans starting in the 5s, savings up to 4%), and strong outcomes for members. It’s popular among educators and the broader community for reliable, member-focused banking.

• People First Bank (ex-People’s Choice Credit Union): Tops YouGov customer satisfaction rankings for 2025 with the highest net satisfaction score among banks (70.4). It’s one of the larger players by assets and is widely used for its competitive products and strong member experience. Great for everyday banking and loans.

• Great Southern Bank (ex-CUA): One of Australia’s largest by assets and a frequent award winner (e.g., for personal loans). It’s commonly used nationwide for home loans, savings, and full banking services. It offers solid value and has a broad reach post-rebrand/merger activity.

• Police Credit Union: Won Mozo’s Australia’s Best Credit Union award in 2025 and has picked up Canstar recognition for green/personal loans. It’s open to the public (not just police) and valued for competitive, accessible products and strong customer focus.

• Beyond Bank: Regularly appears in high satisfaction rankings and is popular for its community-oriented approach and competitive offerings across banking products.

Other notables that frequently rate well include P&N Bank (strong Roy Morgan satisfaction), Bank Australia, and IMB Bank.

Key Advice for Choosing and Using One

Customer-owned institutions generally deliver higher satisfaction than major banks due to their focus on members, often with better rates or lower fees on key products like home loans or savings. Larger ones (e.g., Great Southern Bank, People First) have wider branch/ATM access and more polished apps, while smaller or niche ones excel in personalised service.

Eligibility matters — Many are now open to all Australians, but some (like Teachers Mutual or Police CU) started with specific groups and may still prioritise or offer perks to them. Check directly.

Compare based on your needs: Look at home loan rates, savings interest, transaction fees, credit cards, or app experience via sites like Canstar, Finder, or Mozo. Consider branches (if you want face-to-face), digital features, and any eligibility or location ties.

Practical tips:

• Many participate in shared ATM networks for fee-free access.
• Read recent product terms, as rates change.
• You can often join online quickly.
• For the latest, search comparison sites or the Customer Owned Banking Association (COBA) “Find a bank” tool.

These recommendations reflect recent awards (2025 data) and satisfaction surveys, where mutuals consistently outperform on service and value. What you need (e.g., a home loan vs. everyday account) will narrow it down further—shop around and check eligibility/reviews for your situation.
