Sydney's best mare More Joyous will make her first public appearance since the Cox Plate in a Randwick barrier trial next week.

The prolific winner has been nominated for a 1050m heat on Tuesday which also includes exciting Gai Waterhouse-trained stablemate Proisir.

Another horse who hasn't been seen publicly since the Cox Plate is the Chris Waller-trained Shoot Out and he will go around in a separate heat against Victoria Derby winner Fiveandahalfstar.

Other interesting trial runners include Waterhouse's Breeders Plate winner Whittington, up-and-coming filly Urban Groove and Gimcrack Stakes victor Brilliant Bisc.
