Winter walks around Hobart?

I have signed on to work out of Hobart this Winter.
I may have a single day off each week or if lucky, 2x consecutive days. I will have my own transport and will bring my walking gear with me. I do go out in Winter up here (it snows) but not keen on anything too "out there" so far south.
Thoughts on walks day, or quickish overnighters within reasonable distance of Hobart?
Have looked at Parks site and became excitedly overwhelmed with options, so a local's perspective would be great. My only firm thought so far has been Maria Island.
