We were just the width of a wobble board away from becoming a state of Australia at the time of that country's federation in 1901. So closely were our island and their continent linked in every way except geographically that it seemed to many on both sides of the Tasman that this was a logical step, although we went off the idea before they did and ended up with - basically - just their naff flag.
And look at us now. A classic big-little sibling relationship, which is turning increasingly sour. We have their market for our exports, they have our population to keep their economy going.
In other words, we have a special friendship. Anzac and all that.
But when short of other amusements, Australians like to complain about the number of New Zealanders in their country. Such whines follow the usual lines of those against minorities anywhere. They range from the trivial - the funny way we talk (a little rich coming from them) - to the dangerous and untrue - over-representation in the prison population and in welfare statistics.
Their government, with fires to fight on other fronts, has seized the opportunity for a diversion and, with an arrogance that even a French president would envy, started chipping away at the favours afforded by our special friendship, such as welfare rights. Yet if all the New Zealanders disappeared overnight, Australia would cease to function. Areas where we are over-represented include the professions, commerce and the arts. There's even a few of us in their public service.
