At my school, we had a program called "Live Life", which touched on it a little bit. It was run through Year 9. Good program - should be widespread IMO.
We had something similar to this in year 9 too

Had people come in and talk to us about super, taxes, getting a job, that sort of thing. We also did a first aid course as part of it.
Then in year 12, the school organised to have people from different careers come in and speak to us, and also have people that had followed different paths speak to us too.
Not really a new subject, but I'd like to see an increased availability of LOTE to students.
In terms of new subjects, perhaps something equivalent to the HSC Studies of Religion (though I do realise VCE has Texts & Traditions, but to my understanding they seem reasonably different?). And potentially, also more history subjects.
I think also, something that focuses more on the human aspect of Biology - something that could potentially cross over into the Anatomy & Physiology aspect of things. I found VCE Biology to be too focused on plants
