I don't know how homeschool works where you all are but as a homeschool mum myself I find some of the comments a bit harsh.
Homeschooling was not our first choice for our son but as a child with special needs we were left with no other option. School was his place of torture and high anxiety resulted.
Here the application​ process is lengthy. You must show how you will teach each aspect of the curriculum and list your resources. Yearly testing of the children and reviews are had. Every year you need to show how you will meet the curriculum and children must be present for reviews.
It's not a requirement but I completed a certificate 3 in education support and spent a year working in a school as a support officer before I was confident I could do it at home. Some of the home school mum's I have met are qualified teachers who could see their children would fall through the cracks and not get the education they deserve in a classroom of 30 with 1 over worked and stressed out teacher.
Not everyone homeschools to keep their children from socializing with wordly children and to control everything.
We have met a wonderful bunch of families in the same boat as us via a few Facebook pages and we all want our children to succeed in life and have found a great community to be part of.
We need to be careful not to make generalisations.
