He's the first ever Australian citizen to participate in the Eurovision Song Contest and despite a million eyes being fixated on this wild card entrant, the 33-year-old is handling the entire experience like a pro!
On Wednesday the father-of-two impressed the crowds during rehearsals at the Wiener Stadthalle in Vienna, Austria and has quickly become a fan favourite.
And it's not just the punters taking notice of the Aussie popstar - even last year's winner Conchita Wurst has backed the Battle Scars hitmaker.
"He is a mega star, he knows how this game works. He knows how to perform, he looks good and has a great voice," the 26-year-old recently told Woman's Day.
And we can't help but agree with Conchita. Go Guy!
