A family in northern Tasmania has raised six real white boomers in time for Christmas.

As the Rolf Harris song goes, Santa's reindeer cannot cope with the heat so he has six large white kangaroos, or boomers, pull his sleigh across Australia.

After many years of caring for wallabies, Michael James has bred six white albino wallabies.

"It's only the males that carry the white genes," Mr James explains.

"If you have a grey male and a white female, they'll always have grey joeys."

Mr James says the boomers do not like the sun, but beat the heat by finding a shady spot under the trees.

"As you can see they're just sort of laying around and not doing a lot and getting ready for tonight," he said.

Mr James says the trick is getting them to stay still so they can be harnessed to Santa's sleigh.
