In a first for the national knockout comp, the hosting rights for the cup decider were determined by a live draw on Fox Sports.

Kaine Sheppard, who played for Avondale FC during the competition and recently signed his first professional contract with the Newcastle Jets, made himself an instant hero in Adelaide when he drew the Reds.

Marco Kurz's men will hope home ground advantage will see them go one better in 2018 when they were defeated 2-1 in extra time by the Sky Blues in Sydney.

Adelaide, inaugural Cup champions, are heading into their third final following their 2-0 victory over Bentleigh Greens on Friday.

Meanwhile defending Cup-holders Sydney are into their third straight FFA Cup decider after defeating derby rivals Western Sydney Wanderers 3-0 on Saturday night.
