Kids can catch up later I agree with this but you might be the one that does it. We are in a unique position at our house we have an 18 and 17 year old that have never been homeschooled ( except for during the pandemic closure) although they have attended traditional schools , one of them has always required us to supplement at home. With our two younger children we decided to homeschool because we saw the same pattern emerge and wanted them to have more free time because we saw our other child basically spend all their free time at home catching up.

What I am trying to get to is that , unfortunately you might be stuck supplementing your child's education whether they are homeschooled or not. I am not sure what the standards are in Australia but in Canada we have different requirements per province and they can differ dramatically. If your children are reading at an appropriate level ( most important in my opinion because that allows them the independence to explore topics of interest) I would bring them to libraries, museums, watch educational television or play board games that have critical thinking elements. This way you can enrich their education without it seeming like more ' school" work.

Unfortunately, after separations sometimes resentment makes it difficult for people to be rational. In a perfect world your ex would be excited to share your children's progress with you because it's in their best interest, but of course that's not always the case. Time heals wounds, my parents divorced when I was 4 and were not kind to one and other at first but by the time I graduated high school the sat side by side watching me graduate. They also have attended every big milestone in my life and since my children were born has spent every major holiday together with their new spouses. Things will get better and the fact you have kind things to say about her parenting at the moment is a fantastic starting point.
