Methodology & disclaimer
Rates are collected directly from each bank's published rate sheets and updated monthly (October 2026 shown). Rates are quoted per annum for interest paid at the bank's standard frequency and may change without notice — always confirm with the bank before investing. Ranking is by nominal rate; tax-free and seniors-only products are listed separately because they carry eligibility or contribution limits.
