Cute footage of a young kangaroo poking its head out of its mum's pouch, making the two animals look like a two-headed kangaroo.

The video, filmed in in New South Wales yesterday, shows the Eastern Grey kangaroo sheltering from the heat in in its mum's pouch.

The filmer later wrote online: "Some joeys will stay in the pouch until about 12 months of age.

"Given its size, this one would be close to a year old."

"Although Sydney is now in Autumn, weather records have been broken as it has now experienced a 38th day over 26C," he continued.
