Top High Interest Savings Accounts in Australia (2026), Ranked by Rate

Based on the latest Open Banking data (5 September 2026), the highest advertised rates come from Rabobank (5.90%) and ubank (5.85%). Note the top rates are often introductory or require monthly conditions — check the ‘Conditions’ column.

The maximum rate is only paid when you meet the account’s monthly conditions (or during an intro period). If you don’t, you earn the much lower base rate. Always compare the base rate too — it’s your fallback.

Yes. Interest is taxable income in Australia and is taxed at your marginal rate. Your bank reports it to the ATO. If you don’t provide your Tax File Number, the bank withholds tax at the top rate. This is general information, not tax advice.

Deposits with an Australian ADI are covered by the Financial Claims Scheme (the government guarantee) up to $250,000 per account holder, per licensed bank. Most brands here are ADIs or subsidiaries — check which licence holds your deposit.

The ACCC found roughly 71% of conditional accounts did not earn the bonus in an average month. Our calculator lets you model your real ‘effective’ rate if you sometimes miss the conditions.

Securing the maximum available rate generally requires meeting ongoing monthly conditions rather than simply depositing funds. Most Australian institutions require account holders to deposit a specified minimum amount, maintain positive net savings each month, or complete a minimum number of debit card transactions. Introductory accounts offer higher rates without monthly transaction criteria, but automatically revert to a nominal base rate after a promotional period of several months. Reviewing product terms in the comparison table helps verify which criteria align with your regular banking patterns.

Deposits with licensed Australian banks, credit unions, and building societies are protected under the Australian Government's Financial Claims Scheme (FCS). The FCS guarantees deposit balances up to $250,000 per account holder, per authorised deposit-taking institution (ADI), in the unlikely event that an institution fails. This statutory protection applies to digital-only banks and traditional branch networks alike, provided the provider holds an Australian banking licence issued by the Australian Prudential Regulation Authority (APRA).

Yes. Interest earned on high-interest savings accounts and term deposits is classified as assessable income by the Australian Taxation Office (ATO). Interest paid during the financial year must be declared in an annual income tax return and is taxed at the individual's marginal income tax rate. Australian banks report interest data directly to the ATO, and withholding tax at the top marginal rate may apply if a Tax File Number (TFN) or valid exemption is not provided to the institution.
