Organisers of the BIG DAY OUT festival in AUSTRALIA have announced major changes to the way the event is run following the death of a teenager last year, including the introduction of a “recommended minimum age” of 15 to enter the show.

As previously reported on NME.COM, 15-year-old Jessica Michalik died following a crowd crush at the Sydney Big Day Out earlier this year (January 26).

Following her death, Big Day Out organisers conducted a survey on their official website,, which has led to 12 changes that will be used at next year’s event.

Improvements include more security in the crowd, more “rigidly controlled” crowd surfing at the festival, and a “recommended minimum age to be 15 years old unless accompanied by a parent or legal guardian”.
