About this tool
Australia runs 230 V at 50 Hz on the AS/NZS 3112 type I socket — check your plug, the 10/15/20 A pin ladder and converter need.
The Plug and Voltage Guide for Australia decides whether your device needs a plug adapter, a voltage converter, or nothing at all in Australia. Australia supplies 230 V at 50 Hz on the AS/NZS 3112 socket — the two flat pins in a shallow V plus a vertical earth pin that the IEC calls type I — and the same standard covers New Zealand, Fiji and Papua New Guinea. Enter your plug type and the voltage range printed on the label to get the verdict, the current the device draws and the smallest socket rating that carries it.
Open Plug and Voltage Guide for Australia on AltFTool — it loads instantly in your browser.
Select the plug on your device and type its label minimum and maximum voltage, frequency and rated power — or tap a preset like 'US hair dryer'.
Read the verdict for Australia: whether you need a type I travel adapter, a voltage converter, or nothing, and whether 50 Hz is compatible.
Check the current drawn at 230 V and the smallest AS/NZS 3112 socket rating — 10, 15, 20 or 32 A — that carries it, then click 'Copy result'.
Reports the 10 A, 15 A, 20 A or 32 A outlet the load actually needs, not just a yes or no.
Compares the label voltage range against 230 V instead of leaving it to guesswork.
Marks the Chinese and Argentine variants that fit the socket but do not share AS/NZS wiring.
A type I adapter, the AS/NZS 3112 flat angled-pin shape. Australian sockets have no round-pin provision at all, so a European Europlug, a UK type G plug and a US type A or B plug will all need an adapter. New Zealand, Fiji and Papua New Guinea use the same socket.
230 V at 50 Hz, allowed to sit between roughly 216 V and 253 V (230 V +10% / -6%). Devices labelled 100-240V 50/60Hz — nearly every laptop, phone and camera charger — work with just a plug adapter. A single-voltage 110 V or 120 V appliance needs a step-down transformer, not an adapter.
Because the 15 A version of the AS/NZS 3112 plug has a wider earth pin than the 10 A version, and a 10 A socket has a matching narrow earth slot. Plugs only fit upwards: a 10 A plug goes into a 15 A or 20 A socket, but a 15 A caravan or welder lead needs a 15 A outlet. Filing the pin down is illegal and defeats the point of the system.
About 2,300 W on the standard 10 A outlet, since 10 A at 230 V is 2,300 W. A 15 A outlet allows roughly 3,450 W and a 20 A outlet about 4,600 W. Add up everything on one socket or power board before plugging in a heater, kettle or air fryer.
