I think if you want to compare credit cards there are sites like ratecity you can suss out.
I'd look for one that has a low annual fee and has a rewards program. You can nominate a low limit so there is no temptation to overspend if you are that way inclined.
I do as pp said, buy everything with cc, pay it off weekly, redeem the rewards for coles voucher so every now and then I get free groceries.
