State the standard domestic supply in Australia.

Explanation:
Australia’s standard domestic supply is 230 V nominal, 50 Hz. This means the voltage between live and neutral is about 230 volts RMS, and the system operates at 50 cycles per second. Appliances are designed to work within this range, and the frequency of 50 Hz keeps motors and timing devices running consistently across the country. The other figures refer to different electrical systems: 240 V at 60 Hz would align with some regions outside Australia, 110 V at 60 Hz is typical of North American systems, and 400 V at 50 Hz indicates a three-phase industrial supply rather than a standard home supply.
