How to complete a 2 day trek in 1 day - book a water taxi to pick you up so you don't have to walk the last 10km.
We were so lucky to make this trip - the Tasmanian border closed to Qlders 2 days after we arrived. And at any stage while we were there we may have heard that, on our return to Qld, we would have to complete 2 weeks quarantine in a quarantine hotel room.
It was worth the risk. :)
