DH (MSW) is doing a sort of traineeship as a mental health clinician. His mentor person has lined up all sorts of courses for him to do and while I don't understand the entire thing, he's working with this guy to get clinical experience and work with a Medicare number. (Whatever that means!) But it adds to what he can do because he's learning some new skills that he says can get him a higher paying position. It's only 1 evening a week and appears to be counselling. He says he'll be doing some 'grief and loss stuff' for example.
I don't know if that helps in any way but that's what he is doing to increase his skill set. the rest of the things he has/does all come with a HECS debt
