John Kaye will introduce a bill on Tuesday to shut down the industry, which he says is outmoded, abusive and already in decline.

Last month, it uncovered a mass grave of more than 50 greyhound carcasses near Bundaberg.
Meanwhile, Victorian investigators continue to probe allegations of live baiting at the Tooradin Trial track.
