Police plan to exclude or eject revellers from Saturday's Above & Beyond music event in Sydney if a drug detection dog sits next to them - even if police cannot find any drugs.

In a media release issued on Tuesday night, South West Metropolitan Region Commander Assistant Commissioner Peter Thurtell said that anyone towards whom the dog "makes an indication" will be denied entry to the concert.

“Police will exclude any person from the venue that the drug dog indicates has or who has recently had drugs on them, regardless of whether drugs are located," the statement said.

“Quite simply, if you handle or use drugs you will not be permitted to remain at the venue."

A police spokeswoman confirmed that people whom a dog sits next to would not be arrested nor charged if they do not have drugs, only removed from the $130-a-ticket show.
