Kangaroos and wallabies as companions are not as uncommon as you might think, with several people across the country taking in the marsupials as part of the family.

Dusty the kangaroo lives life as a farm dog with Lilly the golden retriever and Rosie the border collie — but it seems Dusty is not alone.

Suzie Nellist says Wally the wallaby used to live with her — until he found a girlfriend.

"He is still with her and comes back to say hello every now and then," she said.

"Sometimes [he] comes inside and watches telly, then goes off for another few months."

Dusty the kangaroo is convinced he is a dog, and lives with Ashley Stewart and his family at Wittenoom Hills in Western Australia.

He was rescued after his mother was killed when hit by a car in a road accident.

"We weren't sure he would even survive but we fed him and of course he's just taken off from there," Mr Stewart said.

"He lives on the back patio. We've actually had to go and buy a third dog bed for him to sleep in because he used to pinch one of the beds from the dogs."
