MT Ommaney came alive with the sound of school children singing Christmas carols last week, as Kmart launched its annual Wishing Tree appeal.
Kmart Wishing Tree champion Jillian McCarroll said the appeal was in its 25th year.
"This is the largest gift appeal in Australia," she said.
"Our organisation feels it's important to give back to the community, and so far we've collected 5.3 million gifts in the 25 years we've been running it."
Salvation Army spokesman Derek Whitehouse said the two organisations had a 25-year-long relationship that had helped many in need.
"The tags on the tree indicate the age and gender of the child," he said.
"I encourage people to take part, and to put their gifts in a gift bag to make it a little bit easier for us."
Mr Whitehouse said the Salvation Army hoped to assist 500,000 people this year, and they needed the community's help to do this.
