There is a difference between islands and continents in terms of geology. Continents are the largest landmass of a particular continental plate; this holds true for Australia, which sits on its own continental lithosphere and tectonic plate (the Australian plate). By contrast, islands are either extensions of the oceanic crust (e.g. volcanic islands), or belong to a continental plate containing a larger landmass; the latter is the case of Greenland, which sits on the North American plate.
An island or isle is any piece of sub-continental land that is surrounded by water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. A grouping of geographically or geologically related islands is called an archipelago, such as the Philippines.
Just an hour and a half north of Melbourne, Nagambie Lakes is one of Australia’s oldest viticulture areas, with some vines dating back to the mid 19th century. This part of Victoria has long been considered a great day-trip destination for its outdoor activities — waterskiing, rowing, and sailing — and renowned wineries. Now there’s reason to linger, thanks to the November debut of the Mitchelton Hotel, a 58-room resort and spa at Mitchelton Winery. With its fine-dining restaurant, the Ministry of Chocolate, and 5½ miles of trails circumnavigating the vineyard, it’s the perfect base for a weekend in the region. Start your trip with a tasting on-site — Mitchelton is known for its Riesling — before venturing to other nearby wineries like Tahbilk, which has been producing quality vintages since 1861, and Goulburn Terrace, which specializes in natural wines. Other popular local vintners include McPherson Wines, David Traeger Wines, and Box Grove Vineyard. —John Scarpinato
