What are the delivery times for domestic mail?

Australia Post typically offers a range of delivery options for domestic mail, with varying delivery times depending on the specific service chosen. For standard letters, the usual delivery time within metropolitan areas is one to two business days. For regional areas, the time may extend to two to three business days. Express Post is a faster option available for urgent mail, with next business day delivery guaranteed for items sent within the Express Post network. However, if the sender is outside this network, delivery may take longer. It is important to note that delivery times may be affected by factors such as public holidays, weather conditions, and local disruptions. Additionally, during peak periods, such as the holiday season, there may be increased variability in delivery times.
