Sydney is now fighting a war on two fronts - and not liking it one bit.
Bad enough that it has to constantly fend off Melbourne in the rivalry that has burned since the two cities battled to become Australia's capital, lost for both when a remote sheep station was instead picked as the site for the federal citadel of Canberra.
Now Sydney is being hammered by Brisbane, first on the footy field - seven straight losses to Queensland in the State of Origin series - and now seeing the northern city handed hosting rights for the 2014 G20 summit. New South Wales politicians described the choice as an "insult" and warned of the reaction in the world's most powerful offices ... "Brisbane? BRISBANE?" That's if they knew where it was ...
Grinning Queenslanders have simply flipped a smug bird. "Sydney better get used to being beaten by Brisbane" the city's Lord Mayor, Graham Quirk, said. "We're coming to get them on a whole range of events in this city over the next few years."
Sydney has grown used to being the image of Australia with its harbour, Opera House and bridge. It is the nation's biggest city: 4.6 million people at the last count, against about 2 million in Brisbane, which the southerners tend to treat as a pleasant sort of tropical hicksville.
