Summer in Tasmania is peak season and many accommodation choices can book out months in advance.
If you have not been to Tasmania before, it’s worth noting that you don’t need CBD or waterfront lodgings to enjoy the Australian Wooden Boat Festival. Twenty minutes driving opens up many more accommodation choices in nearby areas including Kingston, Bellerive, and the Northern Suburbs a bit further out you will find Richmond and New Norfolk. Our roads, even in summer, are far less crowded than mainland highways and the drive is often very picturesque.
A little longer drive opens up the East Coast, D’Entrecasteaux Channel, the Tasman Peninsula and the Midlands Highway. There is parking available in Hobart at the Domain (5 minutes from the Festival site) and at several CBD car parks. Fees may apply, but they are generally much less than other capital cities.
