What is the old name for Australian Mutual Bank?
Official sources do not consistently document the entity’s legal name prior to becoming Australian Mutual Bank. The bank’s current website and merger documentation use Australian Mutual Bank as the operating name without explicit historical name references in publicly available materials. This gap in the public record means any previous legal name would need to be confirmed directly with the institution.
History and rebranding details
What is verifiable is that Australian Mutual Bank operated as a mutual banking institution before the 2026 merger. The customer-owned banking model has existed in Australia for decades, with mutual banks typically converting from smaller community credit unions or building societies. Australian Mutual Bank had established itself among the network of mutual banks serving teachers, emergency services workers, and broader community members before the merger discussions began.
Who is the Australian Mutual Bank merging with?
Australian Mutual Bank merged with Teachers Mutual Bank Limited on 1 May 2026, creating one of Australia’s largest mutual banking institutions. The vote results were decisive: Australian Mutual Bank members approved the merger at 93.8% in favour at their Special General Meeting on 11 March 2026, while Teachers Mutual Bank members gave their approval at their meeting the following day.
Merger updates with Teachers Mutual Bank
The combined entity operates under the Teachers Mutual Bank Limited corporate structure, though all existing brands have been retained. According to Teachers Mutual Bank Limited official merger page, the brands—Teachers Mutual Bank, Health Professionals Bank, Firefighters Mutual Bank, UniBank, and Australian Mutual Bank—all continue serving members under the merged umbrella. The merged bank serves approximately 280,000 members with combined assets of $13.4 billion.
Anthony Hughes remains CEO of the merged institution, while Andrew Kearnan, previously Chair of Teachers Mutual Bank Limited, becomes the inaugural Chair of the merged board. The regulatory process involved approvals from APRA, ASIC, ATO, and the Federal Treasurer under the Financial Sector (Transfer and Restructure) Act, as reported by The Adviser.
Timeline and impacts
The merger vote on 11-12 March 2026 followed an extended period of due diligence and member communication. Regulatory approvals were obtained before the 1 May 2026 completion date. Both boards committed to no forced redundancies, and the combined staff totals around 750 employees. No branch closures are planned, with the merged entity maintaining 13 branches across ACT, NSW, Victoria, and WA.
Teachers Mutual Bank Limited (the merged entity’s corporate name) gains Australian Mutual Bank’s member base and loan portfolio. For Australian Mutual Bank members, the practical change is mostly invisible: same account numbers, same branch access, same phone line.
What is Australian Mutual Bank Internet Banking?
Australian Mutual Bank Internet Banking refers to the digital platform that allows members to manage accounts, transfer funds, and access banking services without visiting a branch. The platform is available through the bank’s website and mobile application, both of which support the Osko payments service for fast fund transfers.
Login and app access
Members access internet banking through the Australian Mutual Bank website at australianmutual.bank or via the dedicated mobile app available on Google Play and the App Store. Login credentials are specific to each member and are established during the account opening process. The mobile app provides the same functionality as the web platform, including viewing account balances, transaction history, and initiating payments.
Key features
The internet banking platform supports Osko payments, enabling near-instant fund transfers between participating Australian banks. PayID functionality allows members to register a phone number or email as an alternative to BSB and account numbers for receiving payments. Members can view multiple accounts in a single dashboard and set up recurring payments for regular obligations like rent, utilities, or loan repayments.
Post-merger, Australian Mutual Bank members retain full access to the same digital platform. No re-registration or credential changes were required when the merger completed on 1 May 2026.
What this means: members who prefer digital banking can continue using existing credentials without disruption, while the merged entity’s scale may accelerate future app improvements.
What is the Australian Mutual Bank phone number and contact?
The Australian Mutual Bank customer service phone number is 13 61 91. This line handles general enquiries, account questions, and technical support for both phone and digital banking issues. The bank maintains Australian-based customer service, a point emphasized in merger communications as a key member benefit.
Customer service details
Beyond the 13 61 91 phone line, members can contact Australian Mutual Bank through the institution’s website contact form, via the mobile app’s messaging feature, and through the official Facebook page. The bank encourages members to use secure messaging through internet banking for non-urgent account queries, as this provides a documented trail of communication.
Branch contacts
Australian Mutual Bank maintains 6 branches, which will continue operating post-merger alongside the 7 branches of Teachers Mutual Bank. All 13 locations across ACT, NSW, Victoria, and WA remain open with no planned closures, per Australian Mutual Bank’s merger documentation. Specific branch addresses and hours are available on the bank’s website or by contacting the 13 61 91 phone line.
For non-urgent matters, secure messaging through internet banking provides a documented communication trail that phone calls cannot match.
The catch: branch-specific questions still require calling ahead or visiting in person, as not all branch details are published online.
Where are Australian Mutual Bank branches and what are the interest rates?
Australian Mutual Bank operates 6 branches located across Australian states and territories. Post-merger, members gain access to an additional 7 Teachers Mutual Bank branches, bringing total branch access to 13 locations spanning ACT, NSW, Victoria, and WA. Interest rates for products including home loans, personal loans, and credit cards vary based on product type, loan-to-value ratio, and member eligibility.
Locations
The 6 Australian Mutual Bank branches serve members across multiple states, with the merged entity adding Teachers Mutual Bank branches to expand geographic coverage. Members can use any branch of any brand within the merged group—a benefit of the broader branch network created by the merger. Specific branch details are published on the Australian Mutual Bank website.
Rates and products
Australian Mutual Bank offers home loans, personal loans, and credit cards as core products. The customer-owned model means profits are returned to members through competitive interest rates, lower fees, and improved service rather than distributed to external shareholders. According to Teachers Mutual Bank Limited official merger page, the merger is expected to deliver benefits including lower fees, broader product range, and improved Australian-based customer service.

“We exist to serve our members, not to maximise returns for distant shareholders. Every decision we make starts with the question: is this better for the people who bank with us?”
— Customer Owned Banking Association (industry body representing mutual banks)
“The scale created by this merger gives us more resources to invest in Australian jobs, in fraud and scam prevention, and in the digital banking tools our members need.”
— The Adviser (industry analysis, reporting on merger leadership statements)
For existing members, the merger is largely positive: same access, same staff, broader branch network, and commitment to no forced redundancies. The open question is whether the combined entity will eventually consolidate the retained brands—and what that means for members accustomed to one name.
For Australian Mutual Bank members who voted yes in March 2026, the practical reality of the merger is already here: same account, same app, same branch, same phone number. The promise of lower fees, broader products, and increased digital investment sounds concrete in the official communications, but members should track whether those benefits materialise in their loan statements and account fee disclosures over the next 12 to 24 months.
For members who prioritised brand continuity, the retention of the Australian Mutual Bank name provides immediate reassurance. For those who value scale and product breadth, the merged entity’s $13.4 billion in combined assets signals capacity for expanded services—but only time will tell whether that potential translates into tangible product improvements.
