Bulk mail changes

From 3 March 2025 a fee will be introduced for non-conforming bulk mail lodgements.  And from 1 July 2025 Clean Mail will no longer be available. Instead, customers will be able to lodge mail as PreSort Letters Unbarcoded.

Letters deliveries have changed

From 15 April 2024, estimated delivery timeframes for regular and priority letters have changed. Please note, letters may be delivered earlier than the timeframes shown on our website as we make progressive delivery model changes across the country through to the end of 2025.
