Chris Sebastian has only had an hour and a half sleep.
Last night, following his win on The Voice Australia 2020, he says he "just laid awake with a smile on [his] face for about four hours".
"I found out when the rest of Australia found out, so I had to wait till that decision was actually aired on television before I knew," the 31-year-old laughs.
Sunday's The Voice grand finale was pre-recorded, meaning production had filmed each finalist being announced as the winner. The public vote then determined which ending was aired.
"It was awkward because we knew that if we did win, that that was going to be what was played. But because we weren't actually winning in that moment, obviously it was an acting thing. So there's that strangeness to it. But I think the real reaction came when I heard my name on TV," Chris explains to Mamamia.

Chris was with his brother, Voice coach Guy Sebastian, when they called his name.
"I can't even tell you the level of surprise," Chris says.
"My wife was literally holding our baby and she just started running around the house and then she passed our daughter to my sister-in-law and she was just weeping... It was a beautiful moment," he says.
Following the celebration of his win last night, Chris spoke to his brother.
"There's going to be people that are going to question you, or question your win, but this was a public vote by an audited third party," Chris remembers Guy telling him.
"You were the highest vote. So regardless of the noise of people that are angry that you won, you're singing to the people that voted for you and you're singing for the people that want you there and believed in you enough to put you there."
Chris says it was "probably one of the most valuable things that could have been said to me."
