A 22-year-old woman from Sydney's northern beaches has been identified as the final victim to have died in a fiery car crash over the weekend.
Bree Keller, a hairdresser and model from Narrabeen, died after the sports car she was travelling in flipped and burst into flames in the early hours of Saturday morning, her family confirmed to News Corp on Wednesday.
Ms Keller died alongside brothers Steve and Jeff Nasr, aged 39 and 31, when they were unable to escape the burning $200,000 Nissan GT-R R35, which lost control travelling down Goulburn Street at Darling Harbour.
A source who knew the Nasr brothers has also confirmed to Fairfax Media that Ms Keller was the third person in the vehicle who died.
A police spokesman told Fairfax Media that formal identification was still to be completed due to the severity of the fire, but the third and final victim was believed to be a 22-year-old woman from the northern beaches.
Photos on Ms Keller's Facebook and Instagram accounts show the 22-year-old as an underwear and bikini model.
On Instagram, where she has more than 16,000 followers, she is listed as being signed to Australian commercial modelling and promotional agency Edge Models. However, following a Fairfax Media enquiry, the agency said it had previously been "approached" by Ms Keller, but that she had never completed any work for Edge Models.
"Absolutely heartbroken! RIP gorgeous girl," wrote one follower on her most recent Instagram post.
In a Facebook post, Christian Avant, an ex-boyfriend of Ms Keller, wrote of the eight-month relationship the two shared between 2015 and 2016.
"Bree was the last girlfriend I've had ... someone that made me laugh more than anyone I've ever met before," he said.
"Mostly, I feel for her beautiful mother Tania and her equally amazing step dad Peter. If this ever reaches either of you, you'll be in my thoughts forever. Bree was obsessed with you both and it was easy to see why. You both raised a unique and incredible soul ... this is devastating news for anyone and everyone that loved [Bree]."
Other photos show the young woman on a recent holiday in Europe, including in Greece and Italy.
On Sunday, Superintendent Paul Pisanos from Sydney City Local Area Command said Ms Keller and the Nasr brothers involved in the accident "effectively have been burnt alive".
"Considerable speed ... along with a loss of control are two contributing factors [to the crash]," he said.
Superintendent Pisanos said four police officers tried to save the victims, and were "extremely traumatised".
