King Island (or ‘KI’, as the locals call it) is a skinny sliver of land 64km long and 27km wide – a fabulously laid-back place where everyone knows everyone. The island’s green pastures famously produce a rich dairy bounty (you'll be testing how much cheese it's actually possible to ingest over the space of a few days) and its surrounding seas supply fabulously fresh seafood. The island's main settlement is the town of Currie (population 700) on the west coast, and there are east coast settlements at Grassy (population 280) and Naracoopa (population 200).
Interestingly, recent talk on the island has been of seceding from Tasmania and becoming part of Victoria. Poor shipping service from mainland Tasmania has raised the ire of residents, who believe a shift of state allegiance to Victoria would improve the situation. Watch this space!
