Six-time ARIA nominated artist Lior will play at the re-formatted Australia Celebrates Live Concert, on January 25th 2014.
The event, which will be held on the lawns outside Parliament House, will have a fresh new program to honour the outgoing 2013 Australians of the Year.
Lior will be the musical director of an hour-long tribute concert to kick off the festivities. The artist will play a combination of his own songs and Australian classics, chosen by the previous Australians of the Year.
It will be an opportunity for the 2013 award-winners, including Ita Buttrose, to say their final word before the 2014 Australians of the Year are announced.
It is the eleventh year the concert and ceremony have been held in Canberra, but the first year it will include previous Australians of the year in the program.
''The new format takes the elements of the event that Canberra knows and loves, but also adds in a special one-hour tribute to our outgoing Australians of the Year to kick off the evening,'' CEO of the National Australia Day Council Jeremy Lasek said.
''We'll get a chance to farewell the outgoing Australians of the Year both in words and with music.''
Mr Lasek said it will be a chance for the audience to pay respect to the previous award-winners.
''They have always attended the event, but never had a formal part to play. It will be a chance to thank them appropriately for a great 12 months,'' he said.
Lior felt privileged to be involved in the event. "It's a privilege to be part of honouring some of Australia's most inspiring people," he said.
It is the first in a series of announcements for the occasion, which attracts around 30,000 people each year.
The revived event will also combine the 2014 Australian of the Year awards and concert on one stage.
''Previously there were two stages and the audience didn't know whether to focus on the awards ceremony or take their place for the concert,'' he said.
"We saw the need to streamline the event to improve the overall experience, so the audience can find their perfect spot and settle in for a great evening.''
Mr Lasek said removing a stage will create more space and hopefully attract more people.
Last year's line-up included Jimmy Barnes, Guy Sebastian, The Presets and Timomatic.
Mr Lasek said more acts will be announced in early next year, in what will be an all-star line-up of Australian talent.
"We can't wait to reveal who else will be performing on our special tribute and of course, in the concert after the awards," he said.
