COMMENT
Malcolm Turnbull has shown leadership in not overtly seeking to exploit the end of the world as we know it for political gain.
As the Prime Minister says, there is no cause for Australians to be alarmed. We've weathered external shocks before and this one should have limited impact on Australian markets or trade deals. 
As Bill Shorten says, we withstood the last one on Labor's watch - and emerged in better shape than any other of the developed economies. Markets go down when there are shocks, but they rebound, and opportunity can spring from adversity.
The bottom line, though, comes from economist Saul Eslake: "It's hard to know how much bad there is for us out of this, but I think we can be fairly sure there is nothing good for us."
The political reality, one week from polling day, is that external shocks assist the incumbent - and economic shocks will assist an incumbent that voters see as the preferred economic manager.
At a point in the campaign when both sides are stretching credulity with their attacks on each other, Turnbull was wise not to seek partisan advantage and to offer a measured response to the outcome Australia did not want or expect.
Whether the restraint continues, we will see.
Treasurer Scott Morrison was not quite as constrained: "Even in the midst of the uncertainty of the global economy which we are facing, increasing the deficit, increasing the debt and increasing taxes is not going to put the Australian economy in a stronger position, particularly now, particularly right now," he said.
Expect more of this.
The truth of it is that the negatives of this shock transcend politics and offer neither side solace. One is the potential for the decision to dampen enthusiasm around the world for globalisation, openness and free trade, which would hurt Australia.
Another danger is that the vote is indicative of an anti-establishment mood elsewhere, the kind that could see Donald Trump become president and the ultra-right wing seize influence elsewhere. That, too, would be bad for Australia.
One thing that should give a measure of comfort is what this says about voluntary voting, especially when dealing with single issues.
Far better to demand of all who will be affected that they state a preference, as we do.
