Wild bushwalk with dog

I’m hoping someone can help me with first hand experience. I am looking to take our vizsla to Tasmania in a few months. Ideally I’d like to go on a multi-day bushwalk with her, preferably with no facilities and walk only access. Backpack, tent, etc. I know she’s not allowed in National Parks and I know there are a few conservation areas where she will be allowed. However, I’m looking for an extended hike somewhere if possible. Anyone have any specific ideas? Thanks.
