Rare albino wallabies are thriving on a small Tasmanian island due to a lack of predators

Rare albino wallabies are thriving on a small Tasmanian island due to a lack of predators and because locals think they are 'cute', experts have revealed.

The rare genetic mutation of the red-necked or Bennett's wallaby is the result of an imbalance of melanin which gives the creatures snow-white fur and pink eyes, claws and nose.

They are sensitive to sunlight, often have vision problems and are prone to cancer, all of which negatively impact their survival rates.

But an absence of predators on Bruny Island, south of Hobart, has helped its albino wallaby population swell to up to 200, nature park operator Tonia Cochrane said.

Normally these (animals) would be born and they would be predated on or they would just die fairly early but here there's no predators and locals think they are kind of cute,' Mr Cochrane told AAP.

'That means they live to reach breeding age and pass on the gene and there is quite a decent-sized community of them here on the island.'

There is no discrimination within the wallaby community, with breeding between albino and the standard brown wallaby quite common, Dr Cochrane added.

The albino creature is one of the most popular animals among visitors to the island.

'They are just so unusual,' she said.

'They're like something out of Alice In Wonderland ... they don't quite look real.
