Trust Express for your urgent mail

Express Post guarantee currently suspended

Express Post remains our fastest postal delivery option, but current circumstances mean we can't guarantee next-business-day delivery at the moment.

The national next business day delivery network operates between capital cities (excluding Darwin; and for Perth to the CBD only) and the Gold Coast.1
