The Australian credit card market is rich in information. Combined with the latest 2026 data (such as the RBA's removal of card surcharges, ANZ's interest rate adjustments, etc.), I will write a practical guide covering low-rate cards, rewards cards, balance transfer cards, no-annual-fee cards, and the impact of new regulations on cardholders. The article follows a "problem scenario—solution—action guide" structure, uses Australian localised expressions (such as HECS, Coles, Woolworths, Flybuys, Qantas/Velocity points), avoids fabricated data, and the amount ranges are based on search results.
