I don't like that term, sorta gives it a bad stigma. Ex has no involvement with my children's upbringing at all, he hasn't seen them for almost 2 years. I was getting the base rate of $12ish a fortnight for 2 kids. That stopped being paid about 4 months ago, and ex's mother told me that he has recently gotten a well paying job. She urged me to get a reassessment in cs done, which I am now currently in the process of, because with dd starting school next year I will need any extra money I can get to cover those costs.
