While watching my Twitter stream today I saw a Tweet about a new job board, Web Freelancers just for Australian and New Zealand developers. There are other freelance boards around some like RentACoder, elance, and oDesk provide major management tools (billing, time taking etc).
Right now WebFreelancers is free to post a job, so if you have a small web development job pop it up there as it will cost you nothing.
The posting process is quick and easy, with the job ad remaining on the site for 30 days. A bit of an issue as you don’t know if you are applying for a closed job, but I’m sure easy to fix.
