Any subcontractors here?

Hi all.

Mr Minx is tossing up whether to do sub-contracting or not. He was a subbie back in the early 90's, but since has been a salary earner.

He's trying to weigh up pros/cons but I'm not much help.

Can anyone give me advice on tax / super / insurance etc?

I'm fine with the bookkeeping side of things, just not sure how much things have changed in the last 15 odd years and how to gauge expenses etc.

Any advice from any subbies would be much appreciated.
