A Sydney woman says she was denied entry to the Above & Beyond show at the Sydney Showground on Saturday night following the implementation of strict new rules regarding drugs, despite the fact that no drugs were found on her.

Stephanie Korfiatis, 23, a long-time fan of the electronic music band, told a Fairfax Media photographer she was waiting in line outside the venue with a group of friends to have her bag checked by security when a drug detection dog sat beside her.

She was pulled aside, asked to remove an item of clothing and interrogated about her association with illicit drugs.

"I was just about to go through the bag check and then the dog came up around and they pulled me aside and asked me come over to the check-in station," she said.
