We recently had to abort a Franklands Range traverse ending up back at Serpentine Dam, with our transport arranged for Scotts Peak several days later. We asked a passing tourist if they could call Tasmanian Wilderness Experiences when they had mobile reception. We camped by the side of the road expecting to have to walk a very wet 13km to Strathgordon the next day to mobile coverage to find out what was happening. We were just taking down our tents at 8:00am when Kevin drove up with bus. It was a very welcome sight. He'd set off at 5:30am. Definitely above and beyond service.
If you need transport out of Hobart I can highly recommend TWE https://www.twe.travel/
I have no interest in TWE, just a satisfied customer.
