Index Linked could have earned himself a chance at winning a second Caloundra Cup after his strong win at Eagle Farm.

Index Linked ($6.50) put aside some recent unlucky runs to outstay Tucanchoo ($5.50) by a neck with a neck to Malice ($6) in the Group Three Tattersall's Cup on Saturday.

Trainer Chris Waller, who wrapped up the competition to be the Brisbane carnival's leading trainer with the win, had intended to take his winter team home on Sunday.

"It has been a long winter and while we have had six overall winners it has been a slow process," he said.

"Index Linked is actually entered for a race in Sydney next Saturday but I will have a rethink," Waller said.

"Index Linked won the Caloundra Cup last year and he might stay up here for another crack at it. We will make up our mind early in the week."

Waller said Index Linked had been a frustrating horse despite winning 12 races and more than $800,000 in prize money.

"Things haven't always gone his way but he showed with his fifth in the Brisbane Cup at his previous start that he was on the way back," Waller said.

Winning jockey Hugh Bowman said Index Linked had deserved to win another stakes race.

"I was able to follow the right horse into the race and he kept trying the length of the straight," Bowman said.
