With three polls this week from Newspoll, Morgan and Essential all showing Labor on track for a narrow win, the Coalition looks to have run out of time to close the gap, especially with around 3.5 million people having already voted.

However, there remain the undecideds, people so utterly indifferent to politics that they will likely go to vote on Saturday not knowing whom they'll support until the pencil is in their hand. A JWS Research poll from the 2016 election found 23% of voters didn't make up their mind until polling day, with older voters less likely and younger voters more likely to do that. That means an important chunk of the electorate can still be moved even at the very death of the campaign. And the Coalition is pinning its hopes on scaring undecideds away from voting Labor.
