Organisers of the Splendour In The Grass festival have warned security will be tight at this year's event.
Uniformed, plain clothes officers and sniffer dogs will be on duty at all times during the Australian festival, a statement from organisers said.
"Drug detection dogs will be present in Woodford and at the festival. Police random breath and saliva testing units will also be active on local roads," the statement said.
"Anyone caught trying to fence jump or enter the venue unlawfully faces arrest. Fence jumping is trespassing and Splendour has a zero tolerance policy towards anyone trying to enter the festival this way."
Organisers said offenders will be taken to the event's on-site police station for charging under the Summary Offences Act.
"They will then be required to go before a magistrate at a later date where they may face up to $2,000 in fines," the statement said.
"There will be a patron safety hotline that those at the festival can call regarding safety, medical or security matters."
The three day festival will be held across Friday 29th to Sunday 31st July at Woodfordia, near Woodford, south-east Queensland.
