National CEO John Falzon says up to 2000 vulnerable households could be left in dire straits due to Centrelink breaches over the holiday period.
He says "past policy disasters" by the government agency could see the suspension of all income to families and individuals for up to eight weeks.
"We know that in the quarter ending 31 December 2006, 3984 people were forced to live for 8 weeks without any income," Dr Falzon said.
"Our members saw many of these households last year and delivered Christmas hampers and toys.
"We have already received calls from people breached this year and know that, while Centrelink offices are shut, our volunteers will again be delivering a little hope to households otherwise pushed to the margins of society.
"We will not let the Ebenezer Scrooge of past policy destroy Christmas for families this year," he said.
Dr Falzon added that Vinnies welcomes the new Labor Government's commitment to reviewing the current welfare-to-work arrangements for single mums, people with disabilities and unemployed people.
"We are looking forward to a comprehensive review particularly in the context of the new Government's Social Inclusion Strategy," he said.
"It was consistently rejected by the Coalition Government, even when it featured as the key recommendation of the Senate Poverty Inquiry Report in 2004.
"It's time to look honestly at the structures that push people to the margins rather than demonising and excluding people.
