(CNN) One little boy has done so much to help his animal friends in Australia and he's doing it by making one clay koala at a time.

Quiet, he left the room and drew a picture of a kangaroo, a koala and a dingo in the rain. The picture represented his wish for Australia, a wish for rain and wildfire relief, his mom said.

"It was really the first time Owen had made a wish for something other than Lego or something other than himself," Caitlin Colley told CNN on Tuesday. "We asked him if he wanted to help and ... together we came up with this. We could make some clay koalas and give them in response to donations from friends and family."

Six-year-old Owen Colley has made about 55 clay koalas so far.

Owen started making little gray koalas out of clay and his parents set up a way for people to donate to Wildlife Rescue South Coast, a wildlife rescue group in New South Wales. The Colley family is sending one of Owen's koalas to each person who donates $50 or more. So far, he's made about 55 clay koalas.
