It goes without saying (although, boy have we said it, and said it) that police hitting up music festivals with packs of sniffer dogs is a dangerous, exorbitant, and largely-ineffective practice.

Today, the Greens have released figures — based on the NSW Police Standard Operating Procedures and cost-recovery rate — that show just how wasteful this practice is.

Just three police sniffer dogs, working at a music festival, costs taxpayers an obscene $6,000 a hour.

As they break it down, “This means if each dog spends 6 hours at a festival it’s a total cost of $36,041, and if there are 20 festival a year that’s a whopping cost of $720,828.”

“This is on top of the $9 million annual cost of the NSW police detection dog unit that conducts warrantless searches at train stations, pubs and clubs and gets it wrong up to 80% of the time”, they add.
