To be eligible for a credit card, you are required to be over the age of 18 and meet certain requirements. These include income, identification, Australian residency status and credit history. Generally, you will also need to provide details of your assets, expenses and liabilities in order for the bank to determine if you can meet credit card repayments sufficiently.
In some cases, rewards or platinum credit cards will have further requirements as they are tailored to a specific customer base.
