Australian National Maritime Museum (Sydney, NSW): The best things about this museum are the ships and submarines often docked in the harbor out front. You can climb aboard and explore what it's like to be a sailor. Inside are some fascinating displays relating to Australia's dependence on the oceans.
Alice Springs Telegraph Station Historical Reserve (NT): It's not called a museum, but that's what this restored telegraph-repeater station out in the picturesque hills by a spring -- Alice Springs -- really is. From the hot biscuits turned out of the wood-fired oven to the old telegraph equipment, this 1870s settlement is as real as history can get.
Australian Aviation Heritage Centre (Darwin, NT): The pride of this hangar is a B-52 bomber on permanent loan from the United States. But there's loads more, and not just planes, engines, and other aviation paraphernalia -- there are stories, jokes, and anecdotes associated with the exhibits that will appeal even if you don't have avgas (aviation fuel) running in your veins.
Warradjan Aboriginal Cultural Centre (NT): Reader Mari Fagin of Oklahoma City wrote that this small, stylish museum in Kakadu National Park makes for a "very memorable and moving experience! This museum is one of the best of its type we've ever seen." Learn about Dreamtime myths and daily life of Aboriginal people in Kakadu.
Western Australian Maritime Museum & the Adjacent Shipwrecks Museum (Perth, WA): Housed in a brand-new building in the historic port precinct of Fremantle, Perth, this museum tells tales of the harsh Western Australian coastline since the Dutch first bumped into it and abandoned it as useless in the 1600s. Anyone who ever dreamed of finding a shipwreck laden with pieces of eight will relish the displays of treasure recovered from the deep.
New Norcia Museum & Art Gallery (New Norcia, WA): The collection of European Renaissance art in this tiny museum in the Spanish Benedictine monastery town of New Norcia is mind-boggling. The museum has all kinds of memorabilia from the monks' past manuscripts, clothing, instruments, and gifts from Queen Isabella of Spain.
The Migration Museum (Adelaide, SA): This museum gives visitors insight into the people who came to Australia, how and where they settled, and how many suffered getting here. Don't expect a lot of musty displays because this museum is full of hands-on activities.
Australian War Memorial (Canberra, ACT): Given its name, you might think this museum is a bleak sort of place, but you'd be wrong. The museum gives important insight into the Anzac (Australian and New Zealand Army Corps) spirit, including an exhibit on the tragic battle of Gallipoli. There's also a pretty good art collection.
National Museum of Australia (ACT): Using state-of-the-art technology and hands-on exhibits, Australia's newest and most impressive museum concentrates on Australian society and its history since 1788, the interaction of people with the Australian environment, and Aboriginal and Torres Strait Islander cultures and histories.
