In Western Australia Energy Safety is the government department that is responsible for the regulation of all of the electrical industry (and the majority of the gas industry).
In Western Australia all electrical work has to be undertaken by a licensed electrician. You can check out if an electrician holds a valid licence by visiting the Energy Safety website. It will also tell you if there are any restrictions on the holder of the licence.
Energy Safety and the Electrical Licensing Board have developed criteria which all electricians should abide by.
