The need to move to electronic voting. The Preferential Vote count is, by definition, time consuming, especially when there is a close contest.
It's now almost two weeks since the election and two seats, Hindmarsh in SA and Herbert in QLD, are still up for grabs. In Herbert the Coalition are on a wafer thin 44 votes to the good while Hindmarsh looks like going Labor.
Turnbull already has a 76 seats so if they win Herbert they're in with 77 (76 being the magic number ... not 75 as some would have it). But if they had been on say 75 with two seats still to be decided the government would be in limbo with the 'caretaker' provisions in force.
The system needs overhauling. Good that Turnbull and Shorten can agree on something.
