Amid all the noise, smiles, selfies and beers, Chaz Mostert remained speechless after the biggest moment of his Supercars career.
Already a two-time Bathurst winner, Mostert is regarded as one of the best racers in this part of the world. However, a Supercars crown proved elusive — until Sunday.
A collision between teammate Ryan Wood and points leader Broc Feeney stole the early attention in Sunday’s race, before Feeney’s race unravelled further with engine issues.
As Feeney’s race fell apart, Mostert held his nerve to deliver the result required to climb over his rival and win the championship, in what was his 13th attempt since his 2013 debut.
While Feeney’s heartache was laid bare, Mostert’s elation was there for all to see, with the larrikin Queenslander rewarded after years of toil.
"This is pretty wild,” Mostert said on Supercars’ Cool Down Lap podcast presented by Moza Racing.
“What an amazing car. What a chariot that it’s been through this Finals Series.
“Yeah, just lost for words. Like, you dream about this when you're a young kid racing go-karts as a hobby, so you wanna make Supercars one day. That in itself is just such an achievement.
"And then, of course when you get here and you be so competitive, you wish about dream of winning championships and winning Bathurst.
“Just so cool to have my name on that trophy.”
In victory lane, Mostert said his Bathurst beer moment — which went viral — was the catalyst for his big turnaround.
Mostert drowned the sorrows of his first Bathurst DNF with a beer with fans. He then won the next three races, and four races later, was a Supercars champion.
“Instead of us just going, that’s down and out – that was heartbreaking for every single team member,” Mostert said of the Bathurst DNF in PIRTEK Victory Lane.
“The grit of this team and the prep they do for Bathurst every single time … when that [DNF] broke every single person, it was redemption and it was game on.
"We put our arms all around each other – everyone chipped in harder than ever. We used this Finals Series as redemption for Bathurst.”
Mostert paid tribute to father Eddy, his late mother Debbie and the late Paul Mulhearn Snr., who each played a key role in his journey from childhood dreams to Supercars glory.
Additionally, Mostert said he watched the Saturday night concert of Jet — his late mother’s favourite band — in a bid to get some Sunday luck.

"A lot of people sacrificed to get me here today,” the 33-year-old said.
“Mum and dad, they gave up everything to get me here. Such a spoilt kid coming through – didn’t know what a dollar was worth.
“Dad was like, 'if you want to go from go-kart to Formula Ford, we’ll raise the money somehow’. Put the house on the line without knowing what that meant being so young – I just wanted to race cars.
“It paid off. It’s one for the underdogs. It’s so nice to pay them all back – to say they got behind some bogan Aussie out the back of Munruben there and got me to where my dream is.
"I went to the Jet concert last night — Jet was my mum’s favourite band. Unfortunately I lost my mum when I was coming through the support categories.
"A couple of years ago I lost one guy Paul Snr that got me through Formula Ford into development series – I wouldn’t be here without those guys today. So going to Jet last night I felt like I had all the luck on my side.”
