humm90 Mastercard review for Australia, 18-month 0% balance transfers, up to 110 days interest-free and no foreign transaction fees
humm90 Mastercard brings 18 months of 0% balance transfers, up to 110 days interest-free on purchases and no foreign transaction fees in Australia, perfect for Aussies managing big buys and overseas trips

Why Aussies are switching to humm90 Mastercard
The humm90 Mastercard has been turning heads across Australia thanks to its 18-month 0% balance transfers and zero foreign transaction fees. For Aussies juggling big purchases, overseas trips or consolidating debt, the card promises genuine breathing space without the usual transfer charges that bite into savings.
Local shoppers appreciate how the product fits everyday Australian money habits: convert large buys into instalments, avoid sneak foreign fees when travelling, and get extended interest-free days that beat many mainstream cards. It’s a practical option for people who plan payments carefully and want flexibility.
0% balance transfers and flexible interest-free plans
The headline offer is clear: 0% p.a. on balance transfers for 18 months with no balance transfer fee, ideal for clearing existing high-rate debt. If you clear the transferred balance within that window you dodge interest entirely, but be mindful the standard rate of 25.99% p.a. applies afterwards if any balance remains.
On purchases, humm90 Mastercard lets you split spends of $250+ into 9-, 12- or 15-month 0% p.a. instalment plans, and some retail partners like IKEA and Flight Centre offer even longer interest-free terms. There’s up to 110 days interest-free on everyday purchases, though this usually won’t apply if you’ve got an active balance transfer.
Fees, rates and travel perks Aussies value
Fees and rates are straightforward: an annual fee of $99, purchase rate around 25.8% p.a. and cash advance rate about 25.99% p.a., with BPAY repayments incurring a small $0.95 fee. Those higher ongoing rates mean the card suits disciplined users who take full advantage of introductory periods and instalment plans.
Where the humm90 Mastercard really stands out for travellers is zero foreign transaction fees, saving you the usual 2-3% add-on when spending overseas or booking flights. That, plus partner offers and extended interest-free options, makes it an attractive travel and big-ticket purchase companion for many Australians.
Is humm90 Mastercard right for you and how to apply
If you’re disciplined with repayments, often make large planned purchases or travel internationally, humm90 Mastercard can be a smart tool to manage cashflow and reduce interest costs. It’s less suited to people who carry long-term balances after promotional periods, due to the higher standard rates that kick in.
Applying is simple online: check eligibility, have your ID and income details handy, and enter any promo code for the 0% balance transfer offer. Compare the benefits against the $99 annual fee and personal spending habits, and if it lines up, the humm90 Mastercard could help you spread costs and save on overseas spend.
