Can I Use My Hair Straightener (Flat Iron) in Australia?
You'll need a converter and an adapter.
Two things differ here: the voltage and the plug shape. You need both a voltage converter (transformer) rated above your device's wattage and a plug adapter to fit local sockets. Do not plug in with only a plug adapter — an adapter does not change voltage, and the wrong voltage can damage your device or cause a fire.
Based on a typical single-voltage US model — confirm your device's label to be sure.
The short answer
A US 120V single-voltage straightener on 230V power overheats and can scorch hair or fail. Confirm "100–240V" on the plate, or carry a dual-voltage travel model. Frequency does not affect heating.
Australia runs 230V at 50Hz. Australia runs 230V at 50Hz with the unique Type I plug (angled flat blades). Nothing else fits — always pack a Type I adapter; US single-voltage gear also needs a converter.

FAQ
Will a travel adapter let me use my hair straightener (flat iron) in Australia?
No. A travel adapter only changes the plug shape — it does not change voltage. Your hair straightener (flat iron) would still receive 230V.
Do I need a voltage converter for a hair straightener (flat iron) in Australia?
Yes — your device runs on a single voltage that doesn't match Australia's 230V.
What plug type does Australia use?
Australia uses Type I sockets at 230V / 50Hz.
