It was my understanding that all states and teritories now operated (officially, not nessesarily in practice as the tolerances still allow them to operate at 240 and 415) with a nominal voltage of 230 and 400v. SA does and this is in the ETSA service rules. I would imagine that the entity responsible for the transmission of power in the relevant states would also have service rules which would state the nominal voltages. ETSA service rules are available online free, dont know about your area.

A NATIONAL licensing system for electricians, carpenters, plumbers and other tradespeople will replace state-based accreditation after federal and state governments reached a historic agreement to combat skills shortages.
Under the biggest restructure of trades accreditation since federation, companies employing apprentices will receive a national licence, replacing the eight state and territory-based qualifications.
The Australian understands the single standard proposed in a Council of Australian Governments working party report will for the first time give tradespeople accredited in one state a licence to practice across the nation. Under the wide-ranging plan, tradespeople will find it easier to work interstate, with fees and accreditation demands eliminated when they move across state borders.
But unions have argued against a recommendation to give skilled migrants who are qualified in their home country automatic licences to practice in Australia.
In a win for immigration authorities, state premiers have given in-principle support to a "one-stop" assessment process in the report prepared by their own departments and the Department of Prime Minister and Cabinet.
Immigration Department deputy secretary Abul Rizvi said yesterday that streamlining qualifications for migrants was "incredibly important" and insisted that Australian standards would not be undermined.
"We need to make sure the skilled migrants we are getting are job-ready and meet Australia's rigorous standards," Mr Rizvi said.
"The standards won't change. There will be one instead of eight, but it will be the Australian standard."
The Electrical Trades Union backed the plan for a national standard, but argued against streamlining accreditation for migrants.
"We want electrical workers to have a very high standard of skill and training, and very high criteria for people to work in our industry," ETU assistant secretary Kevin Harkins said.
"As far as qualifications go, we don't want people coming from overseas who don't meet our standards. It would impact on the quality of work done and have some influence on insurance."
The Government has come under pressure to pull into line its agency charged with recognising overseas qualifications - Trades Recognition Australia - amid allegations of gross inefficiency aired during parliamentary committee hearings chaired by Liberal MP Don Randall.
The plan to scrap the three-tier system of qualifications - a major hurdle for migrant electricians, hairdressers and other trades needed in Australia - will be considered at the COAG meeting in February.
John Howard committed to developing a "genuinely national system" for apprenticeships at the June COAG meeting amid fears of an impending skills crisis. Australia is facing a shortfall of up to 200,000 skilled workers, with numbers expected to worsen in 10 years, according to industry figures.
The Howard Government this year launched a global recruitment drive in Britain, Europe and India after boosting Australia's skilled migration intake by a record 20,000 places.
Research has shown Australia faces a looming skills crisis, with electricians, plumbers and carpenters set to retire, leaving a vacuum in traditional trades.
Queensland Premier Peter Beattie said his Government had long advocated the need for a national system of accreditation for trades and skills.
"Of course, details will need to be carefully gone through and issues such as health and safety examined," Mr Beattie said.
Victorian Education and Training Minister Lynn Kosky welcomed the recommendations yesterday.
"We have to make the process more streamlined, have a system which ensures that occurs and is consistent, whether that is for domestic people or overseas people," Ms Kosky said.
At the urging of the Victorian Government, the report pushes for secondary schools to be more closely linked to trades training.
In the first step towards mutual recognition of trades, all states have committed to implementing template legislation eliminating paperwork to practise interstate.
The report requires training, immigration and employment guidelines to be rewritten, and outlines a series of steps to be completed by a range of government departments within about five years.
