The Pavlova palaver - why Aussies and Kiwis can't get along
Love thy neighbour is nice in theory. It doesn't always work as a reality for neighbouring nations, even when they live right next door and have many similarities. Just ask the English and the Scots, the Germans and the Dutch, the Greeks and the Turks.
And then there's Australia and New Zealand, who are like two warring children with the same parents. Their sibling rivalry - on and off the rugby pitch - is a battle to rival Kane and Abel. The doubtful sound of discord is revealed in the taunts across the Tasman.
And on the eve of the first Bledisloe played on neutral turf, sibling rivalry is at an all-time high, as both sides banter about their differences and re-live past sporting glories.
In 1908, New Zealand scientist Ernest Rutherford won the Nobel Prize in Chemistry for splitting the atom and his contribution to radioactivity.
Seven years later, Australians and New Zealanders fought as one on the battlefields of Gallipoli. The acronym of Anzac may have once unified them, but unravelling the origins of their rivalry has been harder than splitting the atom.
And equally as volatile.
