The Victorian Racing Tribunal has released footage of disgraced Melbourne Cup-winning trainer Darren Weir using a banned electrical shock device on racehorses.
Weir was banned from racing for two years for using the device, known as a jigger, on three horses at his Warrnambool stables a week before the 2018 Melbourne Cup.
The released footage, dated October 2018, shows Weir administering electrical shocks to three horses as they gallop on a treadmill.
Weir can be seen looking around before touching the device to each horse about eight times.
The ABC understands the same video was shown at his tribunal hearing in March 2024.
In July 2024, Weir was prohibited from training racehorses until September 2026 for using the jigger.
He had previously been banned for four years for possessing the device.

Weir’s lawyers argued the two-year ban for using the jigger should be backdated, as he had already completed a four-year ban for possessing the jiggers.
In September 2024, the tribunal decided not to backdate the ban as Weir operated an unlicensed pre-training business for 18 months between 2023 and 2024.
In July 2025, the Supreme Court dismissed Weir’s attempt to have the two-year ban backdated.
