Hi all,
For work I have had to look through a lot of Australian Standards for some market research I am doing. I ended up getting a bit side tracked with Standards for Automotive Modifications. I stumbled upon this page:
http://www.rta.nsw.gov.au/registration/downloads/vsi/vsi_15_engineering_signatories_november_2010.pdf
If you scroll down, there is a list of registered Engineering Companies for NSW, VIC, QLD, SA & WA which may be helpful for some people. I know in WA, there is a separate page on the WA government's site for Automotive engineers. So this may only be helpful for NSW & VIC people.
I did search, but couldn't tell if this had been posted before. Anyway, hope it helps.
Cheers
Mick
