With the election now underway, let’s look at what either party must do in order to win on May 18.
The Australian Electoral Commission have completed major redistributions in several states due to changes in population. So the electorates of Corangamite and Dunkley that were Liberal are now notionally Labor, due to boundary changes.
The electorate of Port Adelaide in South Australia has been abolished and shifted to create the Victorian electorate of Fraser. The ACT has gained a new electorate named Bean, bringing the total number in the House to 151.
The redistributions, together with the Wentworth by-election and the defection of Julia Banks from the Government means has resulted in a cross bench of 7, both major parties sitting on 72 seats.
The main thing to take away from all of this is that 76 seats are required to form government and with 9 seats are sitting on margins of less than 1%, this means that either party needs a tiny swing towards them achieve majority government.
