Weekly betting market update
New South Wales
The big news in this week’s check of the betting market is New South Wales. Centrebet has Labor on $1.80 to win in 2007. The Coalition is on $1.90. The implied probability of winning is 51 per cent for Labor and 49 per cent for the Coalition. In August last year it was 59 and 41 per cent respectively.
Update 1 March 2006: The odds for the New South Wales 2007 election are now even, paying $1.85 for both Labor and the Coalition.
Tasmania
For the Tasmanian state election, Centrebet has Labor on $4.00 to win 13 or more seats on 18 March (ie. majority government), and $1.20 to win less than 13 seats. The implied probabilities are 23 and 77 per cent respectively.
