The Lord Mayor will make his Brisbane debut in the TAB Open Handicap (1500m) at Eagle Farm on Saturday.
Waller has a strong hand in the race and will also saddle Jaminzah, Veladero and Impasse, with the stablemates all drawing alongside each other in barriers nine to 12.
The Lord Mayor stayed in Sydney for a spring campaign where he won two races in the lead-up to the Group One Metropolitan in which he was unplaced.
He also had a short Melbourne campaign which included a second at The Valley.
The Lord Mayor has had one run since resuming, finishing ninth in the Newcastle Newmarket two weeks ago.
Waller's Queensland manager Paul Shailer said The Lord Mayor was an ideal type for Queensland staying races.
“He obviously has a touch of class and had no luck in the Australian Derby when he clipped heels and while Saturday is short of his distance he should be competitive,” Shailer said.
The Lord Mayor is part-owned by brothers Chas and Cam Stewart who also have likely favourite Order Again in the race.
The Brian Smith-trained Order Again has struggled with injury after winning the 2017 Group Three Grand Prix Stakes but was an encouraging first-up fourth two weeks ago at Eagle Farm.
The Ben Currie-trained Sword Of Justice is the early $3.70 favourite ahead of Order Again at $4.50.
