Try www.aemetal.com.au for metal. They're in Sydney, they send
intercapital parcels Express Post so you receive them next day.
Prices are good, service is excellent. (Happy customer, no connection
and all that).
www.hoj.com.au is another Sydney company. If you join the Jewellers
and Metalsmiths Group in Victoria, you may find you can get a
discount with House of Jewellery. Ask for Selwyn, he's the
manager/owner and is very knowledgeable. They also deliver
interstate and are very prompt. They carry all sorts of hand tools,
electricals, display packaging, books, etc., etc. (again happy
customer, no connections...)
Have you considered using a transformer for your electrical
equipment instead of buying new?
