G'day, Cam, and welcome.
I've been thinking re your post - a bit hard to respond to without more info, and i'm a bit confused.

we have no preference to sleep tent or cabin, however roughing it on the very first attempt might be to much to ask from my 2 brothers.
I'm wondering why 'roughing it on the very first attempt much be too much to ask' from yr brothers, if they are fit and looking for something adventurous and challenging. What sort of age are they? What do you have in mind when you say 'roughing it'?
What sort of length of trip are you looking for? Have you had much experience bushwalking? From your post I'm thinking maybe not a lot. There are any number of brilliant walks here in Tassie, depending on what experience/gear you have or not. If you don't have much, then a guided trip might actually be worth considering, if cost isn't prohibitive. (Edit: if you can consider overseas, you could afford a guided trip.)
Eons ago, I dragged a couple of friends on a trip down the Franklin River, which was everything you seem to be looking for. None of us had experience rafting, and weren't likely to be in a position to get enough experience on our own to take on a trip like that. So we did a guided trip, and it was AMAZING.
Similarly, I did a guided trek in Nepal to Annapurna Sanctuary - again, seems to fit your criteria.
In contrast, my first bushwalk was the Overland Track, with an equally inexperienced friend. Despite bad mistakes and their consequences, it was still a life-changing trip. Just not once in a lifetime, because it only gets better! More experience means the capacity to get to more remote and more amazing places.
