Disgraced greyhound trainer Tom Noble and his wife will have to rely on welfare if the Queensland government seizes the property he used for illegal live- bating, a court has heard.

The Crown on Wednesday urged the Supreme Court in Brisbane to allow it to seize the banned trainer's Churchable property, north of Gatton.

It follows Noble being handed a wholly suspended three-year jail term in 2016 after pleading guilty to 15 counts of serious animal cruelty.

Noble used live piglets, rabbits and possums to develop a "bloodlust" in race dogs at the 16-hectare property between August and October 2014.
