The seat of Frankston is Victoria’s most marginal seat at 0.5 per cent. As such, it’s at the centre of key election promises on both sides of politics – most of them to do with public transport and traffic congestion. The Victorian State Liberal Party has promised to join forces with the federal government to fund an extension to the Frankston train line. Meanwhile the current Labor state government has included Frankston in its proposed $50 billion suburban rail loop. Frankston’s incumbent representative is Labor’s Paul Edbrooke, who has held the seat since 2014. His biggest contender is Michael Lamb of the Liberal Party. But with Labor leading by such a slim margin, the minor parties might be the ones to watch.
