Chris Waller will donate his guaranteed prize money from the staying race at Randwick to drought relief and will also support gynaecological cancer research fundraising on the day.
The trainer has all but one of the runners in Saturday's 2400m-race named in memory of Cindy Sullivan.
"I am fortunate enough to have a number of runners in and as part of the day (jockey) Hugh Bowman and I will donate a lunch in conjunction with Michael Sullivan which will be auctioned off to support this fantastic cause," Waller said in a statement.
"In addition to this I will also donate my trainer's prizemoney earnings from this race to the NSW Drought Relief Fund."
The Waller-trained Raqeeq is the $2.50 favourite to win the $53,375 first prize.
Red Alto, trained by Brent Stanley in Victoria, is at $6.50 in the race which had 11 runners on Thursday.
