Up to 20,000 visitors are expected to converge on Balcombe Heights Estate on Australia Day for the biggest party on The Hills calendar.
Aria-winner Samantha Jade will lead the celebrations at Balcombe Heights, Baulkham Hills.
"We're really excited to have such a talented, young Australian artist in Samantha Jade performing on the day," The Hills mayor Michelle Byrne said of the Australian singer-songwriter who won The X Factor Australia in 2012.
Jade's debut single What You've Done To Me shot straight to No.1 on the Aria singles chart. The accompanying album, recorded in just a few weeks, debuted at No.3. Then, in 2013 she won the Aria for best video for Firestarter.
"Australia Day means so much to me and I think our annual Australia Day event at Balcombe Heights Estate is something really special," Cr Byrne said.
"It's an opportunity for residents and visitors to let their hair down and enjoy some Australian music, some fun rides [$2 each], fireworks . . . and much more."
This year's line-up also includes Sister2Sister School of Singing, the Reptile Man, Ronald McDonald, a skateboard competition, a circus tent where kids under 10 can learn magic tricks and a Dress Up Oz competition.
"January 26 is not just another public holiday — it's a day where we can take some time out to celebrate all that we love about being Australian," Cr Byrne said.
Whether you celebrate at a council event, at a backyard barbecue, playing cricket in a park, going to a sporting event or by spending time with friends and family, it's a special day for us all.
