There are dozens of job portals in Australia, but these are the biggest ones:
Some websites allow you to register, create a profile and add information about your experience and skills. It doesn’t hurt to complete this info in case some employers are actively on the lookout for people like you, but don’t assume that job offers are going to start falling into your lap just because you’ve uploaded your CV to a job board – you will still need to be proactive and apply for jobs yourself.
Once you’ve registered, some websites give you the option of setting up alerts for specific keywords, so you will receive automated emails whenever a new position comes up that satisfies your search terms. This is very handy in streamlining your job search, so make use of it wherever possible.
And of course, keep going with the manual search.
