Semi Final 3 winners pose on stage at the 62nd Eurovision Song Contest at International Exhibition Centre in Kiev, Ukraine.
And after Eurovision she has another big event this year - her wedding to fiancé and fellow X Factor singer Ethan Boroian in August. They will perform sixth in the finals in Kiev, Ukraine on Saturday. Last year's stream was watched by almost two million people, according to Eurovision, making it the third largest music live stream in YouTube's history.
Anja Nissen will join fellow Australian contestant Isaiah Firebrace in the Eurovision grand final.
Though the event has run smoothly, it has done so under the watchful eye of an nearly overwhelming police and army presence at the venue, Kiev's International Exhibition Centre, and key locations in the city, such as Independence Square. She has participated in the Polish selection for the Eurovision Song Contest three times, in 2006 with the song I Wanna Know, in 2016 with Addiction and finally in 2017 with Flashlight.
In 1989 Swiss vocal group Furbaz entered Eurovision with a song in Romansh - the only Eurovision song ever sung in the minority language. There are a number of reasons for this, particularly in the way Eurovision has expanded and absorbed new countries, which has led to neighbours voting in blocs.
Viewers can vote by telephone, SMS and through the official app. Participants will include performers from Belarus, Macedonia, and Serbia.
If the 17-year-old manages to swing all votes which would otherwise be for Russian Federation, he has a real shot. Ukraine used its national broadcaster to mount the production, Sand said, "but we have lots of Swedish, Danish, English and German production colleagues involved, many who were part of last year's Eurovsion in Stockholm". While Australia isn't actually a European country, they have managed to wriggle their way into the contest thanks to years of dedicated fan-girling.
The song became controversial in Russian Federation after its selection to enter the contest, with several politicians and commentators interpreting the lyrics as a thinly veiled attack against the Kremlin and its actions in Ukraine.
Ireland has done best over the decades, winning seven times. (Sidenote: the British after-show, "Liquid Eurovision... a Little Bit More 2003", is hilariously scathing and well worth a watch on YouTube) So where does that leave us in 2017?
Victory comes at a cost, however.
