The appeal supports Aussies doing it tough during the festive season which the Salvos anticipate will reach a new peak under the pressure of the COVID-19 pandemic.

Kianna Spicer from the Liverpool Salvos, in Sydney's south, said Christmas was the busiest time of the year for The Salvation Army.

"And we expect this year to be no different. While Christmas is a time of joy and celebration for many, others doing it tough in our community find it an extremely difficult period for them personally," she said.

"The increased isolation, financial stress and mental health impacts of COVID-19 this year will only exacerbate these issues. The Salvos want to leave no one in need this Christmas, and we need the generosity of the public this year to once again partner with us in support of locals doing it really tough."

Last year during the Christmas period, The Salvation Army distributed more than 64,000 hampers, 26,000 gifts and toys and vouchers worth over $1.89 million to families in need of a hand.

They also provided more than 130,000 meals, more than 66,000 beds and supported more than 10,000 families with accommodation during the festive season.

Ms Spicer said anyone in need this Christmas can reach out to the Salvation Army.

"We'll do all we can to support you. We don't want anyone to go it alone this year, if you need food, gifts, financial support or are feeling lonely, please get in touch with us," she said.

"We are also in need of our local community to dig deep and provide donations to The Salvation Army to ensure that we can support our local community in need this Christmas. We are in need of toys, non-perishable food, monetary donations and these can be dropped off at 51-55 Memorial Avenue, Liverpool.

"Christmas offers us a time to reflect and connect with one another and celebrate the joy of community. Connection will be more important than ever this year, so look out for your mate, check in on family and embrace the true meaning of Christmas."

"The Salvation Army Greater Liverpool will also be located within the local Shopping centres of Liverpool throughout December, collecting much needed funds to go towards assisting our community members in great need. If you see our team, please kindly donate."
