Later that year, Eurovision organisers invited Australia back for the 2016 competition, and we've been participating ever since.

Oftentimes, Eurovision songs are typically genre-less power ballads or upbeat dance songs, usually talking about a desire for world peace and harmony.

SuRie sounds flawless, looks stunning and owns the stage with a maturity that belies her years.

"I am feeling really happy", said O'Shaughnessy, minutes after the results were announced.

Of her song, she added: "I think the song is #MeToo, but it's an empowerment song for everybody, and everybody can find themselves in it".

The UK, represented by SuRie, automatically qualified for Saturday's final as one of the "Big Five" countries.

Supporting Jessica on her Eurovision journey is her boyfriend-of-nine-years Themeli Magripilis.

Named after 2008 Norwegian contestant Maria Haukass Storeng, provoking the Maria Effect at the pre-party is considered a good omen for the grand final. Both semi-finals will be rebroadcast in primetime at 7:30pm.
