Voltage: Australia uses 230-240V AC at 50Hz frequency. North American (110-120V) and European (220V) devices may not work properly or safely.
Plug Type: Australia uses Type I plugs - three flat angled pins in a triangular pattern. Different from US (Type A/B), UK (Type G), or Europe (Type C/E/F).
Adapters: Universal travel adapters that support Type I are essential for overseas visitors. Purchase before arrival or at airport shops (more expensive). Most hotels provide adapters on request.
What to Bring: If traveling with electronics (phone chargers, laptops, cameras), bring a Type I adapter. Dual voltage devices (100-240V) often found on modern electronics. Check your device specifications.
Tips: Outlets in hotels usually near desk for charging laptops. Power banks helpful for all-day sightseeing. Some cafes offer free charging for customers. Appliance boxes show compatibility symbols.
