Teachers Mutual Bank group

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.
