Gary Portelli still believes Fireburn is the one to beat in the 2200 metre feature following her brilliant victory in the Group 2 The Roses at Doomben on May 20.
"It put a dampener on my day when she drew 16 but we rode her back when she won The Roses last time, so she'll just need to do it again," Portelli said.
"The best horses always win these types of races and she's proven in this class and can run the distance and in big fields there's always pressure on.
"I still think she can win the Oaks and the best horses will be there at the 200 metres."
Portelli has won eight Group 1s in his career and believes Fireburn has the potential to be his best ever galloper.
"If she wins the Oaks, she'll be the best horse I've ever trained," Portelli said.
"I've trained some good ones over the years including her father Rebel Dane who won two Group 1s in an era of some very strong sprinters like Buffering."
Fireburn was last year's star two-year-old winning the Group 1 Golden Slipper Stakes and Sires' Produce Stakes in Sydney.
She was edged out chasing a hat-trick of wins at the highest level by the Anthony Cummings-trained She's Extreme in the Group 1 Champagne Stakes in Sydney.
Golden Slipper winners rarely train on to win at the highest level but Fireburn went close when Portelli stepped her up in distance as a three-year-old during the autumn carnival in Sydney.
She finished third in the Group 1 Vinery Stud Stakes at Rosehill in March before a brave fourth to New Zealand Oaks winner Pennyweka in the Group 1 Australian Oaks at Randwick last month.
Portelli then dispatched Fireburn north for her winter campaign and declared immediately after her victory in The Roses that she would win the Queensland Oaks.
"I still think she's the best filly in the race and I don't think there's any real danger as the extra 200 metres is going to suit her better," he said.
"But, it's a Group 1 race and there's no thing as a certainty at this level.
"She was only about 80 per cent fit when she won The Roses and needed a soft run, which she got, and wasn't knocked around by her win.
"She went back home to Sydney a few days after The Roses and she's improved since and will be at her best for the Oaks.
"She thrives on racing and is the one they all have to beat."
In the latest TAB markets, Fireburn has retained favouritism at $3.50 with the Bjorn Baker-trained Renaissance Woman and Australasian Oaks winner Affaire A Suivre on the second line at $5.
Affaire A Suivre is attempting to become only the second horse to win the Australasian Oaks-Queensland Oaks double.
Eight fillies have tried to complete the rare double but only the Chris Waller-trained Egg Tart has been successful when she won the Queensland Oaks in 2017.
