Best Spending/Transaction Account - Student?

Currently just using smart access on Commbank, all my savings are invested, so interest isn't a huge concern but things like cashback? or other benefits that commbank is lacking. Just had to sit in hold for 2 hours because Commbank thought me linking my paypal was suspicious, so not worried about switching atm… Saw the poll thread but there was no real discussion about why each card/bank was voted, and it was somewhat outdated, so opening this for discussion and input.
