The table below summarises the plug types, voltage and frequency of electrical current in both Australia and Sri Lanka.
|Plug Types||I||D, M, G|
|Frequency of electrical current||50Hz||50Hz|
Australia uses Plug Type I.
In Sri Lanka there's more than one socket type in use. You may require more than one adaptor.
The voltage found in Australia and Sri Lanka is exactly the same (230V). You will not need a transformer.
The frequency found in Australia and Sri Lanka is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
