A high-visibility police operation at Splendour in the Grass will spend a third day targeting illegal drug use and supply, a day after a NSW coroner attended to observe the music festival.
Deputy State Coroner Harriet Grahame, who is overseeing the inquest into six recent drug-related deaths at NSW music festivals, on Saturday toured the festival near Byron Bay in the state's north.
Ms Grahame watched a demonstration by David Caldicott - an emergency medicine specialist and the leader of Australia's only sanctioned pill-testing trials - on how drug checking works.
NSW does not currently permit testing of illicit drugs at music festivals, meaning Dr Caldicott only used legal substances.
NSW Police said on Saturday they would not release information about any arrests at the festival in Wooyung until its conclusion.
Ahead of the three-day event, police warned those attending to be aware of the consequences of risky behaviour.
"Festival-goers who choose to do the wrong thing not only compromise their own safety, but also risk the safety of others around them," Superintendent Dave Roptell said in a statement.
"Prohibited drugs are illegal and potentially life-threatening, especially when combined with alcohol, so I urge everyone to behave responsibly.
"Anyone under the influence, or who feels unwell, is urged to seek professional medical attention."
