Australia is the 6th-largest country in the world by landmass and is the first country from the Oceania region (and the second country outside Eurasia, after Morocco in 1980) to participate in the Eurovision Song Contest.

Until 2018, Australia has used an internal selection to select its representatives since they joined the Eurovision Song Contest. Dami Im represented Australia in 2016 with Sound Of Silence, winning the jury vote and finishing 2nd overall. The song won the Marcel Bezençon Award in the composer category. .

Australia was featured as the interval act in the Second Semi-Final of the 2014 Eurovision Song Contest when Jessica Mauboy performed the song Sea Of Flags. Jessica later represented Australia in the Eurovision Song Contest 2018.

In 2019, Australia switched to a televised national selection called Eurovision - Australia Decides. The first edition was won by Kate Miller-Heidke, who managed to reach 9th place at the Grand Final of the Eurovision Song Contest 2019 in Tel Aviv.
