Sydney colt Pierata stands to earn his connections $1.7 million if he can win the Magic Millions 3YO Guineas on January 13, thanks to Racing Queensland's $500,000 UBET 3YO Summer Crowns bonus.
Pierata remains the only horse in contention, following dominant wins in the Winning Rupert Plate on December 2, and the Vo Rogue Plate at the weekend.
A third series heat win at the Gold Coast will secure his connections $1.2 million in prize money, plus an additional $500,000 in bonus money, to be split between the trainer Greg Hickman (15%) and the owners (85%).
Jockey Corey Brown, who is the leading contender to claim the $50,000 UBET Summer Crowns Jockey challenge, eased Pierata down on the line to win by a comfortable 2.5L at Doomben on Saturday.
Brown has been in oustanding form throughout the Queensland Summer Racing Carnival, securing two wins on Pierata, and a host of placings in other UBET Summer Crowns Series races.
He leads the tally on 25 points, five clear of legendary Queensland hoop Jim Byrne.
Brisbane's premier trainer Tony Gollan heads the UBET Summer Crowns $50,000 Trainer Challenge, after he trained an incredible three series heat winners at Doomben on December 16.
He picked up additional points when last year's $500,000 UBET Summer Sprint Crown bonus winner, Most Important, finished second in The Buffering.
The race over 1350m may have also uncovered a new star, with the Matt Dunn-trained Care To Think finding room late to surge away to an impressive win. The win means the $400,000 UBET Summer Sprint Crown bonus will not be won this season.
The $500,000 UBET 2YO Summer Crown will also remain untouched, after Lee Curtis was able to win the G3 BJ McLachlan Stakes with his filly Meryl.
Earlier, Gai Waterhouse and Adrian Bott missed out on a $50,000 UBET Summer Crowns Series bonus with talented miler Cabeza De Vaca in the Bernborough Handicap.
Racing Queensland offered a $100,000 bonus to the connections of any horse who could complete the G2 Villiers and Bernborough Handicap winning double, and $50,000 for any horse placed 2nd to 4th in the Villiers who could win the Bernborough.
Cabeza De Vaca raced wide throughout the 1600m feature, with the Desleigh Forster-trained Someday saluting at huge odds in an emotional victory.
