A woman undergoing hotel quarantine on the Gold Coast has breached her isolation conditions after receiving a packet of cigarettes delivered via a flying drone.

A man is believed to have been operating the drone from outside the Crowne Plaza at Broadbeach last Sunday, July 11.

The drone was observed delivering a packet of cigarettes to a woman in hotel quarantine by flying to her balcony.
