Higgins: why is the Liberal heartland turning its back on the party? – video
Gay Alcorn visits Melbourne's inner east – a seat that usually gets very little attention during the campaign and has been held by the Liberal party since 1949.
With the retirement of incumbent MP Kelly O'Dwyer and discontent over the dumping of Malcolm Turnbull, many of the 'small-l' Liberals in the seat are abandoning the party.
Labor and the Greens are confident about their chances as issues such as the Adani coalmine and climate change remain prominent.
The Liberals have by no means given up and have devoted significant resources to holding the line against a possible doomsday scenario.
Labor's plans to reform the capital gains tax and franking credits, which have upset wealthy retirees, could play into their hands.
