A standard domestic postage stamp for a small letter in Australia currently costs $1.70 for regular (basic) postage.

Current stamp price

  • Basic postage (small letter, up to 250 g, within Australia): $1.70 per stamp.
  • This rate came in after a 20 cent increase from the previous $1.50 price.
  • Concession stamps and seasonal greeting stamps stayed at lower, unchanged prices (e.g., concession and seasonal greeting rates were not increased in the 2025 change).

Very near‑term changes

  • Australia Post has proposed another increase from $1.70 to $1.85 for small letters, but this is tied to a regulatory process and is not yet in everyday effect at post offices.
  • The proposal was lodged in January 2026, with planned changes for later in 2026 once approvals and final dates are confirmed.

Quick practical tips

  • If you have older $1.20 or $1.50 stamps, you can make up the difference by adding extra low-value stamps so the total reaches the current $1.70 rate.
  • For the very latest figure on the exact day you post, it is safest to check Australia Post’s online calculator or ask at a post office counter, as formal approval of new prices can shift the live rate.
