Pay on or before the due date
Moneysmart suggests a direct debit or automatic transfer set for the day after your pay goes in, plus a calendar reminder.
Avoid cash advances
A fee is usually charged and interest runs from the day you withdraw the cash.
Use the right card overseas and online
If you often buy from overseas merchants, the ACCC suggests considering a credit or debit card that doesn't charge international transaction fees.
Review what your annual fee buys
Once a year, compare the fee with the value you actually got from rewards and extras.
Cancel cards you don't need
Pay the balance to $0, redirect direct debits and redeem any points first.
