Savings Rates Haven’t Been This Good in Over a Decade

The RBA’s decision to raise the cash rate to 4.10% on 17 March 2026, its second consecutive hike this year, has pushed savings account interest rates to levels not seen since before the global financial crisis. For savers, this is genuinely good news in an otherwise challenging economic environment.

While rising rates are painful for mortgage holders, they present a real opportunity for anyone with cash sitting in a transaction account, an emergency fund that could be working harder, or short-term savings earmarked for a goal like a house deposit or holiday.

This guide covers the best high-interest savings accounts available in Australia right now, how to compare them properly, the tax implications most people overlook, and strategies to maximise your returns without taking on investment risk.

How the Cash Rate Affects Your Savings

The RBA cash rate is the interest rate on overnight loans between banks. When it moves, most banks adjust their savings and lending rates accordingly, though not always by the full amount or at the same speed.

Here’s how the cash rate has moved through 2025 and 2026:

DateRBA DecisionCash Rate
February 2025Cut 0.25%4.10%
May 2025Cut 0.25%3.85%
August 2025Cut 0.25%3.60%
February 2026Hike 0.25%3.85%
March 2026Hike 0.25%4.10%

After the March hike, banks have been progressively announcing savings rate increases. Some pass on the full 0.25%, while others pass on less. The speed varies too: some banks increase rates within days, while others take several weeks.

Which Banks Have Passed on the March 2026 Hike?

As of late March 2026, here’s where the major banks and leading neobanks stand:

Note: Rates change frequently. Always verify current rates directly with the provider before making decisions.

Understanding Bonus Rates vs. Base Rates

This is the single most important thing to understand about high-interest savings accounts, and the area where most Australians lose money without realising it.

How Bonus Rates Work

Most of the headline rates you see (5.25%, 5.35%) are “bonus rates” that only apply when you meet specific conditions every single month. Miss the conditions in any given month, and you earn only the base rate.

Common conditions include:

  • Depositing a minimum amount (usually $1,000 or more) each month
  • Making a minimum number of debit card purchases (typically 5-20)
  • Not making any withdrawals from the savings account
  • Growing the account balance compared to the previous month
  • Being within a specific age range

The catch: Base rates without the bonus are typically between 0.05% and 1.50% p.a. That means if you miss conditions in a single month on a $100,000 balance, you might earn just $4-$125 for that month instead of $440+.

A Real-World Example

Let’s say you have $80,000 in a savings account with a 5.25% bonus rate and a 0.55% base rate. You meet the conditions for 10 out of 12 months because you needed to withdraw money twice for unexpected expenses.

ScenarioMonths at Bonus RateMonths at Base RateAnnual Interest
Perfect (12/12)120$4,200
Missed 2 months102$3,573
Missed 4 months84$2,947
All base rate012$440

The difference between perfect compliance and missing just two months is $627, or roughly $52 per month. That’s real money, and it’s why choosing an account with conditions you can realistically meet is more important than chasing the highest headline rate.

The Best No-Conditions Savings Accounts

If you don’t want to worry about meeting monthly conditions, these accounts pay a competitive rate regardless of your behaviour:

AMP Bank GO Save: 4.60% p.a.

This is currently the standout no-conditions option. You earn 4.60% on balances up to $500,000 with no deposit requirements, no purchase requirements, and full withdrawal flexibility. AMP Bank is an authorised deposit-taking institution (ADI), so your deposits are covered by the government guarantee up to $250,000.

Best for: Emergency funds, short-term savings where you might need access, and anyone who doesn’t want to micromanage monthly conditions.

Macquarie Transaction Account: 2.50% p.a.

While not a savings account per se, Macquarie’s transaction account now pays 2.50% on all balances after the March hike. For money you’re actively using (paying bills, everyday spending), this is significantly better than the 0% most transaction accounts offer.

Best for: Your everyday banking balance, replacing a big four transaction account that pays nothing.

Strategies to Maximise Your Savings Returns

Strategy 1: The Two-Account Approach

Keep your emergency fund in a no-conditions account (like AMP GO Save at 4.60%) and direct your regular savings into a high-bonus account (like ING Savings Maximiser at 5.25%).

This way, you can always access your emergency fund without jeopardising your bonus rate on the savings you’re building. Set up an automatic transfer of $1,000 from your pay into the bonus account each month to ensure you meet the deposit condition.

Example setup:

  • Emergency fund ($30,000) in AMP GO Save at 4.60% = $1,380/year
  • Regular savings ($50,000) in ING Savings Maximiser at 5.25% = $2,625/year
  • Total: $4,005/year on $80,000

Compare this to leaving $80,000 in a big four transaction account at 0%: you’d earn nothing. Even at the average savings rate of around 2.5%, you’d only get $2,000.

Strategy 2: Laddering With Term Deposits

If you have a larger cash balance and want to lock in today’s rates (in case the RBA cuts later in 2026 or 2027), consider splitting your money across savings accounts and term deposits of different lengths.

PortionAmountProductRateMaturity
Emergency fund$30,000AMP GO Save4.60%Ongoing
Short-term$25,0003-month term deposit4.50%June 2026
Medium-term$25,0006-month term deposit4.65%September 2026
Longer-term$20,00012-month term deposit4.80%March 2027

As each term deposit matures, you can reassess rates and either renew or redirect the money. This gives you a blend of accessibility and rate certainty.

Strategy 3: Offset Accounts for Mortgage Holders

If you have a mortgage, an offset account may be more valuable than a savings account, even if the savings rate is technically higher.

Here’s why: interest earned on a savings account is taxable, but money in an offset account reduces your mortgage interest, which is not a taxable event.

Comparison on $50,000:

  • Savings account at 5.25%: Gross interest $2,625, tax at 34.5% (incl. Medicare) = $908 tax, net return = $1,717
  • Offset account against mortgage at 6.34% (average variable rate): Interest saved = $3,170, no tax payable, net return = $3,170

The offset account wins by $1,453 in this example. The higher your marginal tax rate and mortgage rate, the bigger the offset advantage.

Important caveat: This only applies if your mortgage is on a variable rate with an offset facility. Not all loans offer offsets, and some charge a higher rate or annual fee for the feature. Run the numbers for your specific situation.

Strategy 4: Salary Sacrificing Into Super Instead

For higher-income earners, salary sacrificing into superannuation may deliver a better after-tax return than keeping money in a savings account, depending on your time horizon and tax bracket.

Contributions to super are taxed at 15% (up to the $30,000 annual concessional cap from 1 July 2025). If your marginal tax rate is 37% or higher, the tax saving alone is significant:

Income BracketMarginal Rate (incl. Medicare)Tax on $5,000 Savings InterestTax on $5,000 Super ContributionTax Saving via Super
$45,001-$135,00034.5%$1,725$750$975
$135,001-$190,00039%$1,950$750$1,200
$190,001+47%$2,350$750$1,600

Of course, money in super is locked until preservation age (currently 60 for most Australians), so this strategy only makes sense for money you genuinely won’t need before retirement.

The Tax Implications Most Australians Miss

Interest Is Taxable Income

Every dollar of interest you earn on a savings account must be declared in your annual tax return. Your bank reports it to the ATO automatically via the PAYG system, so there’s no way to avoid it.

At the current top savings rate of 5.35%, a $100,000 balance earns $5,350 per year. Here’s what you’d actually keep after tax at different income levels:

Taxable Income (excl. interest)Marginal RateTax on $5,350 InterestNet Interest (After Tax)Effective Rate
$18,201-$45,00021% (incl. Medicare)$1,124$4,2264.23%
$45,001-$135,00034.5%$1,846$3,5043.50%
$135,001-$190,00039%$2,087$3,2633.26%
$190,001+47%$2,515$2,8352.84%

For high-income earners, the effective after-tax return on even the best savings accounts is under 3%. That’s still better than 0% in a transaction account, but it changes the calculus when comparing alternatives like offset accounts, super contributions, or tax-effective investments.

The TFN Withholding Trap

If you haven’t provided your Tax File Number (TFN) to your bank, they’re required to withhold tax at the top marginal rate (47%) on all interest earned. This is a common issue when people open accounts online and forget to complete the TFN declaration step.

Check your account settings to ensure your TFN is on file. If tax has been over-withheld, you’ll get a credit when you lodge your tax return, but that means your money is tied up with the ATO unnecessarily.

The Government Guarantee: What’s Actually Covered

The Australian Government’s Financial Claims Scheme (FCS) guarantees deposits up to $250,000 per account holder per ADI (authorised deposit-taking institution). This covers:

  • Savings accounts
  • Term deposits
  • Transaction accounts
  • At-call deposits

It does not cover:

  • Managed funds
  • Shares or ETFs
  • Bonds held directly
  • Cryptocurrency
  • Foreign currency accounts at non-ADI institutions

Important: The guarantee is per ADI, not per account. If you have $200,000 in a savings account and $100,000 in a term deposit at the same bank, only $250,000 of your total $300,000 is guaranteed.

If you have more than $250,000 in cash, spreading it across multiple ADIs ensures full coverage. For example, $250,000 at CBA and $250,000 at Macquarie Bank gives you $500,000 of guaranteed deposits.

Which Institutions Are ADIs?

All Australian banks, building societies, and credit unions are ADIs regulated by APRA. However, some newer fintech platforms are not ADIs themselves and instead hold deposits through a partner ADI. Check that your institution is on APRA’s list of ADIs if you’re unsure.

When Savings Accounts Don’t Make Sense

While savings accounts are excellent for emergency funds, short-term goals, and cash buffers, they’re not ideal for long-term wealth building. Over the past 30 years, the Australian share market (ASX 200 total return) has averaged approximately 9-10% p.a., compared to the long-run average cash rate of around 4%.

After inflation (currently running at approximately 3-5%), a savings account earning 5% is delivering a real return of just 0-2%. For money you won’t need for five or more years, a diversified investment portfolio is likely to deliver better long-term outcomes, even accounting for market volatility.

The right approach for most Australians is:

  1. Emergency fund (3-6 months’ expenses): High-interest savings account
  2. Short-term goals (1-3 years): Savings account or term deposit
  3. Medium to long-term (3+ years): Diversified investments (shares, property, super)

How to Switch Savings Accounts

If you’re earning a low rate, switching is straightforward:

  1. Open the new account online (most accounts can be opened in 10-15 minutes)
  2. Provide your TFN to avoid withholding at the top rate
  3. Transfer your balance via bank transfer (usually arrives in 1-2 business days)
  4. Update any direct debits or automatic transfers to point to the new account
  5. Close the old account once everything is moved (or keep it if there’s no fee)

There’s no penalty for closing a savings account, and no impact on your credit score. The only thing you lose is any loyalty bonus from your existing bank, which is rarely worth the difference in rates.

The Bottom Line

With the RBA cash rate at 4.10% and possibly heading higher, there has never been a better time in recent memory to ensure your savings are working as hard as possible. The difference between the best and worst savings rates in the market is over 5 percentage points, which on a $50,000 balance is the difference between earning $2,675 and earning virtually nothing.

Take 15 minutes to compare your current rate with the options above. If you’re earning less than 4% with no good reason, you’re leaving money on the table.

Frequently Asked Questions

What is the highest savings account interest rate in Australia in March 2026?

As of March 2026, the highest introductory savings rate is 5.40% p.a., while the highest ongoing bonus rate is 5.35% p.a. from Rabobank. The best no-conditions ongoing rate is 4.60% p.a. from AMP Bank's GO Save account on balances up to $500,000. These rates reflect the RBA cash rate increase to 4.10% on 17 March 2026.

Do I have to pay tax on savings account interest in Australia?

Yes, interest earned on Australian savings accounts is taxable income. It must be declared in your tax return and is taxed at your marginal rate. For someone earning $90,000 salary plus $2,500 in interest, the interest is taxed at 32.5% (plus 2% Medicare levy), meaning you'd keep approximately $1,638 after tax. You can offset some tax by claiming deductions or contributing to super.

Are Australian savings accounts covered by a government guarantee?

Yes, deposits up to $250,000 per account holder per authorised deposit-taking institution (ADI) are protected under the Australian Government's Financial Claims Scheme (FCS), administered by APRA. This covers savings accounts, term deposits, and transaction accounts at Australian banks, building societies, and credit unions. The guarantee does not cover investment products like managed funds or shares.

What is the difference between a bonus rate and a base rate on Australian savings accounts?

The base rate is the interest you earn regardless of your activity. The bonus rate is an additional amount paid when you meet specific conditions each month, such as depositing a minimum amount (often $1,000+), making a set number of card purchases (often 5-20), or not making any withdrawals. If you miss the conditions in any month, you only earn the base rate, which can be as low as 0.05% p.a. at some banks.

Should I choose a savings account or term deposit in Australia in 2026?

It depends on your needs. Savings accounts offer flexibility to withdraw anytime, while term deposits lock your money for a fixed period (typically 3-12 months) at a guaranteed rate. In March 2026, the best 12-month term deposit rates are around 4.60-4.80% p.a., while the best savings bonus rates reach 5.35% p.a. However, savings bonus rates require meeting monthly conditions. If you're disciplined about meeting conditions, a savings account may pay more. If you want certainty, a term deposit guarantees your return.

How much interest will $100,000 earn in a high-interest savings account in Australia?

At the top ongoing bonus rate of 5.35% p.a., $100,000 would earn approximately $5,350 in gross interest over 12 months (before tax). After tax at the 32.5% marginal rate (plus 2% Medicare levy), you'd receive approximately $3,504 net. At the best no-conditions rate of 4.60% p.a., the same $100,000 would earn $4,600 gross or approximately $3,013 net after tax at the same rate.
