British band Coldplay entertained the crowd at Adelaide

In a statement, the organisers of Big Day Out said: "Our hearts and thoughts go out to her family and friends in this time of deep sorrow."

Sydney Police are preparing a brief for the coroner investigating the death.

Thirty others were injured in the crush - and six more taken to hospital.

The band continue to blame poor security and festival producers for the incident.

Jessica's parents, George and Barbara Michalik, have also said not enough was done to prevent the tragedy.

But festival organisers have denied this, saying the cause of the trouble was excessive heat and crowd excitement.

After the Auckland opening of the six-date touring festival, Limp Bizkit suggested to organisers that the stage be altered to a "T" shape.

Heat

According to Katsis, this stage shape has been used at festivals around the world, including Reading, Berkshire, to break up the crowd while increasing the view for more fans and preventing surges forward.

Meanwhile, it was Adelaide's turn to host the Big Day Out as it rolled in for its penultimate date.

Bad publicity and soaring temperatures reaching 40 degrees (Celsius) kept crowd numbers down to about 16,000, compared with 22,000 for other years.

Festival organisers went out of their way to ensure a smooth day.

There were PA warnings about the dangers of crowd surfing and special "mist tents" were set up to spray cold mist on hot music lovers.

Despite the warnings, many fans insisted on frenzied dancing and crowd-surfing early in the day as local band Frenzal Rhomb performed.

Minute's silence

St John Ambulance Australia said around 400 people were treated for minor injuries and mostly heat-related illnesses. One person was taken to hospital early on with a fracture.

Highlights of the day included UK acts PJ Harvey and Coldplay.

Brisbane act Powderfinger attracted the biggest crowd. During their set, lead singer Bernard Fanning stopped and asked the audience to acknowledge one minute of silence to remember Jessica.

Underworld DJ Darren Emerson also asked for one minute of silence for the teenager.

The final leg of the Big Day Out takes place in Perth on Sunday.
