Engineering Consulting Rates in Australia?

[SeoulBigChris]

As the title says, what’s a ballpark range for electronic engineering consulting fees in the region? Let’s assume an engineer with 40 years experience that is very broad, spanning everything from systems engineering, hardware design, firmware coding, small scale manufacturing, and remote field testing. Say, typically hourly (or daily) rates vary from xxx to zzz dollars. Please note which currency, please, given that the dollars are different.

I have no idea how to quote a potential gig down under.
