Joliestar is by Zoustar, who won a Group 1 Coolmore Stud Stakes over the Flemington 1200m and has passed on straight-track ability to his progeny.
Two of Sunlight's three Group 1 wins came down the straight, in the Coolmore Stud Stakes and Newmarket Handicap, while Zoutori is a Newmarket winner and Ozzmosis provided him with a second Coolmore Stud Stakes success.
The Newmarket Handicap will be the second start for the campaign for Joliestar, who finished third first-up in the Group 2 Expressway Stakes (1200m) when caught wide.
Her previous two runs were seventh placings in the Golden Eagle and The Everest last spring when she had little luck on each occasion.
Joliestar had a familiarisation gallop at Flemington under Damian Lane last Friday morning and Waller said giving her a start over the 'Straight Six' serves a dual purpose with the remainder of her campaign not set in stone.
"We love to give our horses an experience of running down the straight because there are so many great races here at Flemington, or even overseas if we want to travel, so it gives you that option."
Joliestar will be joined in the Newmarket by three-year-old stablemate Gatsby's, who was scratched from Saturday's $1m Inglis Sprint to be saved for the Group 1.
