Your Central Reference for Australian Mains Power
Australia uses a 230V AC, 50Hz mains power system delivered through the AS/NZS 3112 plug standard. This section covers the standard plug configuration, its variants, mandatory safety features, and the specifications that govern every mains-connected product sold in Australia and New Zealand.
