Australian dollar dips overnight as political crisis worries global investors

The Australian dollar dipped overnight as global investors worried about the political standoff in Canberra and a likely early election. 

The dollar fell 1.4 percent to 72.4 US cents as currency traders backed away from Australia as a safe destination. 

ABC's Peter Ryan says until now business leaders have been numb to the uncertainty but are now deeply concerned about fallout to the economy.
