Australia Post is set to raise the cost of sending letters, with the price increases due to take effect from 1 September. The change means Australians will need to budget for higher postage costs, continuing a trend of rising prices for traditional mail services as the postal service adjusts its charges.

Specific details of the new pricing, including the exact increase, were not included in the available article text beyond confirmation of the September implementation date. The move reflects Australia Post's ongoing efforts to manage costs amid declining letter volumes and rising operational expenses.
