A second horse trainer has been charged with several "serious welfare breaches" including giving electric shocks to horses.
Ben Currie is accused of using Taser-type devices, known as "jiggers", on two occasions and unauthorised "shockwave" treatments.
He is also charged with failing to report bleeding horses to stewards and race-day treatment breaches.
It follows compatriot Darren Weir being banned for four years, also for possessing jiggers.
Queensland Racing Integrity Commissioner Ross Barnett said an investigation into Currie began on 7 April last year.
The accused has been called to a stewards' inquiry on Monday where he will be asked to give reasons why he should not be suspended.
