The Scot finished last season with five tournament victories in succession, culminating in World Tour Finals success over arch rival Novak Djokovic to claim the No 1 ranking to go with Wimbledon and Olympic gold
A win in Melbourne would give Murray the third leg of a career Grand Slam and having reached the final on five occasions he will have every hope of at least emulating that run - and going one better than the five defeats he has suffered.
Four of those have been at the hands of Djokovic, including last year when the Serb beat Murray in the first of two Grand Slam final meetings of 2016 but Murray now has the belief the final six months of last year gave him
Significantly, Murray has Ivan Lendl back in the player's box, the Czech who has helped guide Murray to all three of his Grand Slam titles so far and Olympic gold at London 2012.
He kicked off 2017 by reaching the final in Qatar, but he ran into Djokovic who triumphed in three sets and the pair look set for another huge collision in the final in Melbourne.
Murray has reached at least the last eight in each of the last seven years in Melbourne, and the semi-final in six of those - it's only the title that continues to elude him.
