Carlton are like the respectable son who turns bad ends up with a $20k debt. As a parent you could let them work it out for themselves and they'll probably end up unemployed on crack with bad credit for life, or you could pay off the debt and try and get their head above water, problem is when you give them the easy way out they don't learn anything and end up in trouble again. A boarding school in western Sydney or the Gold Coast might be an option.
Ha ha - send em to boarding school indeed.
