Aussies are encouraged to vote for their favourite artist and song to represent the nation on the world's biggest stage. The winner will be revealed during the Live TV Final which will be broadcast on SBS on February 26.
Isaiah, who missed out to winner Montaigne in 2020, said he was "over the moon" to be jumping on stage for Eurovision – Australia Decides 2022, which will be filmed on the Gold Coast.
"When I first represented Australia at Eurovision in 2017, I was 17, it was my first time in Europe and I feel like everything was a blurry dream that went by so quickly - I've grown so much as a singer, a performer and as a person since then and I've definitely got unfinished business," he said.
"I can't tell you anything more except that I'm singing a duet with someone incredible and that we co-wrote the song. What I can tell you is that I cannot wait to share everything with you and that Eurovision – Australia Decides is going to be the biggest party on the Gold Coast."
Meanwhile, former Young Divas star Paulini said she can't wait to finally perform in front of a crowd again after the pandemic put an end to live music.
"That also means it's been a little while since I've been able to belt out any of the big notes I'm known for. But that is something the audience can definitely expect to hear in my new single which I'll be performing at Eurovision – Australia Decides," she said.
"Eurovision to me is like the Olympics for singers! It brings together so many countries and cultures— and while it's a competition I see it as uniting much of the world through music."
Jaguar Jonze, who also competed in Eurovision - Australia Decides in 2020, said she's "honoured and bubbling with excitement" to compete for a shot at Eurovision 2022.
"The imagination, creativity and talent of the performances is always so inspirational, it's such a special place to express yourself as a musician and an artist," she said.
"My song is going to be a moment that celebrates our resilience and the little steps that lead to big change, as well as push my creative boundaries to another level. So much has happened since we were all together, and being back with the added strength of my Eurovision family and fanbase will make it a show worth waiting for."
As for what they'll all be singing, more than 700 songs were submitted to the Eurovision – Australia Decides song portal during the four-week entry period.
The shortlisted songs were then matched with artists, who have since released their tracks. See the full playlist on Spotify here.
Eurovision - Aus Decides will be broadcast live on Saturday, February 26 at 7:30pm (AEST). Watch live on SBS and SBS On Demand.
