some advice, dont bother with job sites
its too relaxed and easy to just keep plodding along
you need to get out and sell yourself
speak to friends, post up on here what work you are after
write letters to employers that you would like to work for
even go and visit them, ask to speak to the employment manager
and just have a general chat (i got my job at bigpond doing this).
if i was looking for sysadmin work i would speak to companies i would be keen to work for, people like bigpond, optus, uecomm, motec, etc etc any companies that u know of who would be cool, i reckon that motec sysadmin job would have been ace, mainly cos im interested in engine management crap and sysadmin is good so good to combine both
anyhoo a bit of advice
