Betting agency sportsbet.com.au has declared the election over, paying out A$1.5 million in bets on the Coalition.
"As far as Sportsbet's betting markets are concerned, the Abbotts can start packing up their belongings ahead of their imminent move to Kirribilli House," agency spokesman Haydn Lane said. "The Coalition are nowinto Black Caviar-like odds to win the election."
The agency priced the Coalition at $1.03 with Labor at $11.50.
Betting markets have been a good predictor of election results.
In 2010, 147 favourites out of 150 in Sportsbet electorate markets went on to win the seat.
"I once worked for an opposition that was careering towards the inevitable victory - and it didn't happen. [It's] proof that there is no such thing as an unlosable election and I think this election is very, very tight."
