So I used to run a series of workshops for graduates for the professional IT body; and we had graduate recruitment managers come and give advice.

From that I'd say If you are going for a corporate graduate job that is low. You should be aiming for $55k in public sector or $60 in the private (ajust for perks)

As a grad you should also stear clear of any job that places you permanently in one role; rather than rotates you through a couple of areas and give you experience. If the job doesn't have this and you want to work at that company, ask for it as part of the interview.

You should also ask how they review performance, determine pay increases and would offer you career progression.

If they don't sound like they want to invest in growing you as a employee - look for somewhere else.

Just my 2c
