can certainly hit $aud 100 / hour and upwards for full-time contract gigs with bigcos (banks, finance, telcos). can hit that with less than 5 years experience.

if the client knows what they're doing they may also assess for ability, not just years experience. but at least some big clients don't know what they're doing and are overrun with whatever resources of varying ability bodyshops manage to palm off onto their projects.
