Canberra is a picturesque 20th-century concoction on the banks of Lake Burley Griffin that has struggled to establish itself as the focus of Australia's national identity. It has often been perceived as a 'fat cat' town of politicians and bureaucrats living off the rest of the country.As Australia's capital, Canberra pulls out the big guns when it comes to sightseeing. Souped-up national versions of art galleries, war memorials and libraries come extra-large and with lashings of grandiose gravitas. The city's impressive sights are ringed around its focal lake.
