How are you getting on ?
I found this link has lots of helpful information https://www.homeschoolingdownunder.com/homeschooling-australia/

My advice would to try and keep to a routine. Start time, set times for subjects, break times. Routine makes it easier

I honestly schooled my son for years 11 and 12. It was difficult as I had to keep on at him to do the work. But worth it as his grades went thru the roof. So proud of him

I’ve heard it is important to organise social activities for home schooled children as they miss out on that aspect.

The Education Department may also also be able to give you additional resources?

I think there is a few online groups for parents wishing to home school

Maybe there is an online group or association and maybe a school will be able to link you in with home schooling options? I believe home schooling is still overseen? Maybe contact your education department for advice?
