Thousands of people will pack the banks of Adelaide's River Torrens on Saturday night to welcome 2017 under a sky illuminated with fireworks.  The Adelaide City Council expects about 30,000 people will join the city's biggest New Year's Eve celebration at Elder Park, featuring live music, food stalls and rides from 6pm.  In keeping with tradition, the festivities will be topped off with fireworks at 9pm and midnight, this year to a backdrop of beats from local artist DJ TRIP.  The council says security has been boosted for the celebration in the wake of recent world events, to help minimise the risk to the community.  But City of Adelaide Lord Mayor Martin Haese says that will not hamper the fun.  "Such measures will not detract from our celebrations and we encourage everyone to join us for Adelaide's best and biggest New Year's Eve party," he said.  The weather will be a far cry from Adelaide's storms during the week, with only light showers expected on the day and a moderate top of 26 degrees and low of 16 degrees.  Adelaide Metro is offering free transport on all of its buses, trains and trams between 5pm on Saturday and dawn on Sunday to help people get to and from the party.  SA Police said they will still have a high presence on roads to nab drink drivers and will be attending all major New Year's Eve celebrations across the state.  A spokesperson said there is still no specific information to suggest any terror threat for SA but the national terrorism threat level remains at probable.  "South Australia Police encourages everyone to go about their daily business as usual, while remaining alert to suspicious behaviour or activity," they said.
Beefed up security for New Year's Eve celebrations in the heart of Adelaide will not get in the way of people having a good time, the city's council says.
