New license regulations for NSW music festivals won't be in place until after summer, it's been revealed, following another overdose death of a young reveller at a Sydney dance party.
Callum Brosnan, 19, died on Sunday and three others were taken to hospital following suspected overdoses at the Knockout Games of Destiny dance party at Sydney Olympic Park on Saturday night.
The death of Mr Brosnan comes after two people died after overdosing at Sydney music festival Defqon.1 earlier this year.
Premier Gladys Berejiklian has again rejected pill testing at music festivals but hopes new licensing regulations will help - eventually.
"When you embark on having these events you are privy to those new regulations that we put through and we expect the highest level of safety to be conducted by all these event organisers," the premier told reporters on Monday.
"All of our agencies are on high alert because they know how strongly I feel about this.
"We're absolutely hopeful that (young people dying) never happens again and the strongest message we can send to people is 'Do not take illegal substances'."
Liquor & Gaming NSW on Monday confirmed the state's new music festival rules won't be in place until March 2019.
"The new licensing regime will include detailed safety management plans with measures targeted to the specific risks of each festival," a spokesman told AAP.
"It will ensure a consistent approach and cover liquor, health and policing measures."
Organisers holding music festivals over the summer are being encouraged to work closely with Liquor & Gaming, local councils, NSW Police and NSW Health "to reduce the risks of drug-related casualties at festivals".
The NSW parliament last month passed the Community Protection Legislation Amendment Bill which introduced jail terms of up to 20 years for those who supply drugs which cause death.
In October the government accepted in principle recommendations made by an expert panel convened to advise how to keep people safe at music festivals.
The recommendations included providing more support for festival health workers and trialling on-the-spot fines for drug possession.
