Neighbourhood Christmas wonderland restored after little boy's plea.

A Sydney woman has granted a little boy his Christmas wish by turning her family home into the North Pole using more than 100,000 lights, having announced an end to the spectacular annual display in 2014.

Every year, Helen and Kostas Mallikopolous open up their Christmas wonderland at Cremorne in Sydney’s north to thousands of strangers.

But in 2014, the couple, originally from Greece, announced the end of their annual extravaganza.

Helen’s daughter, Vicki Burnside, said the decision was made after her mother almost died while putting up decorations a few years ago.

“It was pretty bad. Mum was trying to straighten these large penguins on the roof and then fell a few metres to the ground,” said Vicki Burnside.

“She was rushed to hospital and she had to spend the next four months on the couch, doing nothing. That was hard because mum and dad run a cafe up the road.

“But this year, mum got a knock at the door from a little boy, begging her to put up the display and so she just couldn’t say no, he was so excited.”

The Mallikopoulos family spend two months decking out their Cremorne home with the elaborate display, which includes a snow machine creating a North Pole illusion, and illuminated Santas and Angels perching on the roof overlooking a manger.

Joanna Mercurio lives up the road and said the show always boosted the Christmas spirit of the neighbourhood.

“It’s so beautiful. Helen is like Mrs Claus — she really brings people together and that’s what Christmas should be about,” she said.

Ms Mallikopolous said her love for the festive season dated back to when she was a child growing up in Greece.

“My brother and I went searching for a tree one Christmas and I nearly drowned. We were trying to cross a swollen river on the back of a donkey with the tree and then we got into trouble,” she said.

“Christmas hasn’t always been kind to me after that and falling off the roof, but I still love it.”

Donations given to cancer research

While there is no cost to come and have a look at the house, Ms Mallikopolous put a donation box out the front.

“For about four years, we have been raising money for cancer research because my daughter Vicki is a nurse,” she said.

“This year, we are hoping to raise about $6,000 to help Cancer Council New South Wales, so fingers crossed.”

Angie Burnett from Cancer Council New South Wales said everyone was extremely thankful to the Mallikopolous family for their support.

“The Mallikopoulos family have created a wonderful opportunity for North Shore residents to not only enjoy a spectacular Christmas light display, but also raise funds to help beat cancer,” she said.

“The money raised by the Mallikopoulos Christmas light display will support initiatives of Cancer Council NSW such as conducting and funding world-class research, implementing cancer prevention programs and offering information and support for those affected by cancer.”

The Mallikopolous family don’t give each other presents on Christmas Day. Instead, they put their money towards the light display.

“The electricity bill is usually quite hefty — around $1500 just for the month of December, so we all pull together and pay for it, instead of giving gifts,” Vicki Burnside said.

“Don’t get me wrong, we give the kids some presents and we have the big fat Greek lunch, but that’s about it.”

Santa is expected to drop in on the Cremorne home on the evenings of December 23 and 24.

“We just love seeing the smiles on children’s faces and the joy our home brings to people from all over the world,” Vicki Burnside said.

The Mallikopolous family Christmas display will run until January 8, 2017.
