It's worth checking if there are any local homeschooling groups in your area: these are really worth finding as you will meet plently of people who've done it all before and are happy to discuss how they do it and also your kids will make friends.

A good place to find groups is at the HEA (Home Ed Australia) or HEN (home ed networks) websites. These sites also advertise for home ed functions ( a couple of years ago there was a conference in Sydney lots of good international speakers attended). They also have resources re getting started, the legalities etc.
