The Lions skipper played the full 80 minutes as the Lions survived a last-minute penalty attempt by the Wallabies to win the match at the Suncorp Stadium.
Kurtley Beale missed that kick from 46 metres and Lions held out for a 23-21 win to take a crucial 1-0 lead in the three-Test series.
Lions' tries came from Warburton's Welsh team-mates George North and Alex Cuthbert, backed-up by three penalties and two conversions from Leigh Halfpenney.
"That was entertaining, that's for sure," said Warburton afterwards. "It was way too close for comfort. The last 20 minutes was so hard, we really had to dig in. Credit to Australia, we can expect a lot more from the last two Tests. Only half the job done.
"It's out of your control when the opposition have a kick in the last minute. It's a massive delight, we've got some momentum, we've got the balling rolling and we're looking forward to next week."
Lions now play Melbourne Rebels on Tuesday before the second Test next Saturday, June 29 at the Etihad Stadium, Melbourne and the final test the following Saturday, July 6, in Sydney.
Warburton, who incredibly went to the same school in Cardiff as Gareth Bale, told us back in February about his love of Spurs.
"My father was born in London and brainwashed me and my twin brother Ben to support Spurs from age six when I got my first shirt. He would always tell me 'you're Spurs in the blood now boys!' He had supported Spurs most of his life too."
