NT or Tas?

Seen as though I’m taking a couple of weeks off after I finish up at my current job, I’m thinking of going away for a few days. Two places that came to mind are: Northern Territory or Tasmania. Both sounds a little boring… BUT,

- I don’t want to go away for too long, so overseas is out of the question.

- I’m not a big fan of a “tropical” type holiday either – so let’s cross out anything up North (eg Great Barrier Reef).

Doesn’t leave much else! I’m leaning towards NT, but not too sure at the moment. I also want to spend a few days in Sydney (since I haven’t been there this year! LOL).
