A 19-year-old woman has died of a suspected drug overdose after attending a Sydney music festival on Saturday.

The woman, from the New South Wales Central Coast, was rushed to Westmead Hospital about 6pm but died later in the evening, bringing the total number of drug-related deaths at dance festivals to five over the past six months.

The electronic hip-hop FOMO music festival was held amid increased scrutiny on drug-taking and a renewed debate surrounding pill testing at music festivals across the country.

The unidentified woman was just one of more than 11,000 glittered-up revellers who turned up to the electronic hip-hop event in Parramatta park, in Sydney's west.

Saturday's searing temperatures set the scene for the international line-up, headlined by American rap superstar Nicki Minaj, as party-goers strutted their stuff in glittery and eye-popping outfits.

Skimpy shorts, leotards and see-through mesh were the order of the day for many young women who sported some bold and bright outfits.

The warm weather attracted an array of barely-there festival outfits as festivalgoers attempted to combat the hot afternoon sun - busting out their most outlandish threads.

Many took to adorning their faces and bodies with glitter, complete with sparkling and brightly-coloured outfits.

The festival has already toured across several cities in Australia and New Zealand, beginning in Brisbane earlier this month and ending on Sunday with a final Melbourne show.

It was Sydney's turn to host the sold-out show on Saturday, with partygoers making the most of the sunshine as the mercury hovered around the high 20s to low 30s for most of the day.

But behind the scenes and away from the headline acts, more than 130 police officers and drug dogs watched on to oversee some festival fanatics who took to the party a little hard.

Festival gates were manned by dozens of police officers who stopped and searched ticket holders before they were allowed in.

Local acts for festivalgoers to enjoy included Sydney DJ Anna Lunoe, Australian rapper and singer Carmouflage Rose and Triple J Unearthed winner LALKA

Unlike many other festivals, FOMO promises all acts perform on the one stage so revellers don't miss out on their favourite artists due to clashes

Dozens of revellers were kicked out of the event before they had even stepped inside, while some were escorted from the venue for intoxication or fighting.

Event organisers issued a warning ahead of the day advising attendees to note the patron safety hotline and first aid facilities.

'We're here to help, please party safe,' the organisers said over the event's Facebook page.

Officers searched a total of 146 people, 54 of whom were found in possession of drugs. Two were charged with possession.

An investigation is now underway into the circumstances surrounding the 19-year-old's woman's death with officers from Parramatta Police Area Command appealing for anyone with information to come forward.

Police will prepare a report for the coroner.

In a separate incident, about 6pm, a young woman was found collapsed in a toilet cubicle.

The New South Wales government previously rejected pill testing but Premier Gladys Berejiklian indicated earlier this month that she would consider it if the government was shown evidence it could save lives.

The pill testing debate comes after the death of Josh Tam, 22, who died from a suspected overdose at the Lost Paradise music festival near Gosford, on the New South Wales Central Coast.

Mr Tam, from Toowong in Brisbane, was rushed to Gosford Hospital at 8pm last Saturday after he ingested an unknown substance.

Nicki Minaj wrapped up the event for the final act of the night, setting the crowd alight and supported by hip-hop group Rae Sremmurd and recent Kanye-collaborator Lil Pump.

Local acts included Sydney DJ Anna Lunoe, Australian rapper and singer Carmouflage Rose and Triple J Unearthed winner LALKA.
