In 2015 Australia’s multi-billion-dollar greyhound racing industry vowed it would clean up its act.

A damning investigation at the time had exposed the preventable deaths of as many as 17,000 young dogs a year - revelations so shocking the government of the day rushed to implement an ultimately short-lived ban.

Almost a decade later, Greyhound Racing New South Wales (GRNSW) - the epicentre of the sport in the country - is back in the spotlight for alleged abuse, due to the work of one whistleblower.

In an explosive report made public by lawmakers, the organisation's former chief veterinarian has described the industry as a hotbed of “exploitation and suffering”, claiming that dogs are being raced at “barbaric” rates, euthanised without cause, or left to rot in metal cages when they can no longer compete.

Executive heads are rolling, and an inquiry, which GRNSW says it “welcomes”, has been announced to investigate the accusations, as calls from critics to have greyhound racing outlawed grow louder.

But despite evidence of slipping public support, the state’s premier has said he won’t shut down the sport, prompting a standoff with those calling for that to happen.

“The reality is the greyhound racing industry cannot exist without systemic animal cruelty,” says NSW Animal Justice MP Emma Hurst.

“It will be shut down – it’s just a matter of when.”

Australia has been touted as the world’s largest commercial greyhound racing industry - with roughly 60 tracks in operation. New Zealand, the US, the UK and Ireland are also home to markets, but none operate at the same velocity.

Thanks to online betting, Australia’s industry has seen rising profits in recent years, turning over A$8.3 bn ($5.6bn; £4.3bn) in 2023 - with 75% of the money coming from Victoria and New South Wales (NSW), according to the greyhound protection organisation GREY2K.
