Mozo snapshot

The Platinum Credit Card from Bank of Sydney certainly lives up to its name with a heap of rewards befitting a platinum card including both an introductory purchase rate and balance transfer offer as well as a whole range of complimentary insurances. Bank of Sydney cardholders will even be able to earn $8 cash back for every $1,000 they spend on eligible purchases.

That's why the Platinum Credit Card was named a 2021 Mozo Experts Choice Award winner in the best Platinum Rewards Credit Card category.

Key features

Let’s start with the fundamentals. The Bank of Sydney Platinum Credit Card comes with an annual fee of $129 which is quite competitive for a platinum card, plus it’s offering a 6.99% introductory purchase rate (for the first 6 months) which may come in handy if you’re likely to carry a balance over that period. Just bear in mind that this reverts to the much higher 18.49% purchase rate afterwards. 

Cardholders who are sticklers for paying off their balances each month will also be pleased to hear that the card comes with 55 interest free days. 

Looking to take charge of some existing credit card debt? The Platinum Credit Card features a 0% balance transfer offer for the first six months, though after that period it will revert to 18.49% so it could be wise to pay off your balance before then. 

A platinum card wouldn’t be much without some platinum perks though, but Bank of Sydney really delivers in that respect. For every $1,000 Platinum Credit Card holders spend on eligible purchases, they’ll be able to receive $8 cash back into a linked Bank of Sydney BOS savings account

Speaking of perks, the card also comes with some handy complimentary insurances including international travel insurance, extended warranty and price purchase protection.

Who is it good for

The Bank of Sydney Platinum Credit Card could be a great option for anyone wanting a platinum credit card with a range of benefits and perks, especially if they can take advantage of the introductory purchase rate of balance transfer offers.

Any catches

While the Platinum Credit Card can certainly accompany you on your next overseas trip, it’s worth bearing in mind that any purchases you make abroad or on an overseas website will attract the 3.00% foreign exchange margin.

How do we calculate these points?
How do we calculate the rewards?

To work out the "Rewards value minus fees" in our Rewards Revealer we:

  • calculate how many points you'd get each year,

  • figure out how many flights or gift cards or cashback credits you could get for those points,

  • work out what that's actually worth to you,

  • take off the annual fee you'd pay.

More details:

  • Our calculations are designed to help you compare the value of different rewards schemes. To do this, we've looked at earning a one-way Sydney-Melbourne flight excluding taxes and charges, a return Sydney-London flight excluding taxes and charges, a $100 shopping Gift Card and $100 cashback. Most cards will also offer other rewards, which may be worth more or less than the ones we've shown.

  • We have made no allowance for bonus points for using your card at specific merchants, introductory offers or special offers. We have not assigned any value to instant discounts, insurances, ticketing and concierge services or other such benefits.

  • Rewards value calculations do not take credit card interest into account. If you do not pay off your card each month you may be better off looking for a card based on interest rates than on the value of rewards.

  • In products that have more than one card, a different mix of spend between American Express / Visa / Mastercard will give different results. Mozo's Rewards Revealer lets you choose the mix based on the way you would use such a product, and gives you tailored results.

  • We assume flights purchased with airline points are 'classic' or 'reward' economy seats with restricted seat availability. 'Any seat' rewards will probably cost more.

  • To compare the value of flight rewards, we sample online retail flight prices once a quarter based on the average price on a Wednesday 3 months in advance but outside NSW school holidays. For domestic flights we take the lowest available fare from each flight on that day from Qantas Red e-deal, Virgin Australia Saver including baggage and Jetstar Starter including baggage. We calculate the average price excluding taxes and surcharges for each airline, and also the average across all airlines (which we use when rewards are travel agent vouchers). For international flights, we take the lowest available fares on that same Wednesday from each of Qantas, Emirates, Malaysian, Etihad, Singapore, Cathay Pacific and Thai, assuming a return flight 2 weeks later, calculate the average price before taxes and surcharges and use this as our assumed cost of a flight on any airline.

  • Shopping rewards are based on $100 gift cards from a major national department store.

  • We make every effort to ensure our calculations are correct and up to date but make no guarantees.
