As well as Mystic Art, the Gympie trainer will also campaign current race dogs French Appeal and Black On Gold at the Ekka, as well as three young pups who are yet to debut, but are likely to be at the races in the coming months.
Mystic Art has registered three wins and 13 minor placings from 40 career efforts.
The brindle and white bitch is nearing retirement and Roche is hopeful of finding a perfect home for Mystic Art at the Ekka this year.
“We'll just put it out there that she's come to the end of her career and if anyone's interested then, we will get her ready to be rehomed,” she said.
“We really don't actually have that much trouble rehoming greyhounds.
“We normally put the word out there that we've got something coming up and they normally do get rehomed pretty quickly.
“For a couple of years, we've taken dogs down that we've actually rehomed, but we still take them down to the Ekka for their new owner.
