Skip to content GENERATIONS of Tasmanians hold fond childhood memories of holidays in the Central Highlands. Summer stays in the family shack, long bushwalks, and endless hours of fishing for trout in yingina/Great Lake. James Johns is one of these Tasmanians. He has a longstanding, heartfelt connection to the region, and is now helping a new generation of visitors create their own memories. James is the grandson of David Johns, the founder of well-known Tasmanian car dealership DJ Motors.
