New Year’s Day celebrations have kicked off for thousands of music lovers in Sydney and Melbourne as revellers in skimpy and barely-there outfits flock to Field Day and Let Them Eat Cake.

Concert-goers in Sydney didn’t let grey skies dampen their spirits as they prepared to party to performances from headline act Rüfüs Du Sol, G Flip, Mall Grab, Romy and English DJ and producer Ross from Friends.

The event, which has been running since 2002, is considered an institution, particularly among electronic music fans who will often stay in on New Year’s Eve to make the most of the festivities.

NSW Police officers were seen leading sniffer dogs around the grounds as they searched attendees making their way through the front gates of the ticketed event.

Bikini tops, denim shorts and tiny skirts were the outfit of choice for women while men wore buttoned shirts and colourful bucket hats as they milled around the grounds.

Temperatures in cloudy Sydney reached a maximum of 23C on Monday, with lows of 21C in the afternoon.

Meanwhile in Melbourne, the sun shone down on attendees of the Let Them Eat Cake festival in Werribee, about 35kms west of the CBD, with temperatures reaching the high 20s.

Included in the line-up is a series of home-grown and international acts including Barry Can’t Swim, BICEP, salute, Club Angel, DAWS, Laura King, Gumm and ABSOLUTE.

The Melbourne festival is described as ‘where boundaries between art and reality blur in an all-day dark immersive club atmosphere’.

Wild scenes on New Year’s Eve as Sydney is hit with travel chaos, Gold Coast revellers take things a little too far… and some keep the party going at the beach until sunrise

Australia has welcomed in 2024 in style with wild celebrations lasting long into the night.

Some revellers’ celebrations ended with a refreshing ocean swim at dawn, while others found themselves waiting hours for Ubers and trains until the early hours after watching the fireworks.

But there were a few partygoers who took things a little too far and were escorted away by police officers.

More than a million people flocked to vantage points across Sydney Harbour to catch the fireworks extravaganza, while others lived it up in pubs, clubs and at parties across Melbourne and the Gold Coast.

Revellers spilled onto the street after the clock struck 12, scrambling to make their way home or, in some cases, keep the party going.

The muggy weather saw blokes unbutton their shirts and glammed-up ladies in summer dresses ditch their heels and go barefoot.

The midnight fireworks over the Sydney Harbour Bridge were watched by millions of Australians

Couples walked arm-in-arm while others hit the deck, too exhausted to wade through the endless crowd after a long day of action.

More than 8.5 tonnes of fireworks went up in smoke alongside 80,000 pyrotechnic effects and the sounds of jubilant cheers.

For some, it was a 17-hour wait after queuing from the early hours of the morning to snag a premium spot.

But it was worth it as the clock struck 12 for the families, friends, world travellers and locals alike who enjoyed the front-row display of pyrotechnics, a smoking ceremony, AI-driven projections onto the harbour bridge and illuminated boats on the water.

Smaller groups were seen dancing on the pylons of the Harbour Bridge while children looked on in wonder.

By 5pm most major vantage points around the foreshore had already reached capacity with the Sydney Opera House full by 11.30am.

Janna Thomas, visiting from Germany, is spending her first New Year’s Eve in Sydney and grabbed a spot in the Botanic Gardens.

‘It’s unbelievable we are here. It feels surreal,’ she said.

Having waited in line since 7.30am, she described the scene as ‘total madness’.

‘It’s not so easy to find a good place to sit but the view is incredible.’
