She’s Exotic was on debut for the Dunn stable when winning at Ipswich in August and has since contested two events at Doomben unsuccessfully.
Tietar is second-up from a spell in its event after finishing eighth at Ballina when resuming.
Meanwhile, Mallyon has two other leading mounts at Grafton with both being for Newcastle trainer Kris Lees.
Mallyon rides Star Venture in the same event that Another Cashie contests, while he is on Sethfire in the CRJC AGM 12 November Maiden Plate (1710m).
Star Venture has been placed in five of 13 starts, while Sethfire resumed with a strong finishing fourth at Port Macquarie and had been placed in three straight before being spelled.
