He may be nearly 17,000km away, but five-year-old Charlie's generosity knows no bounds.

Originally from Adelaide, little Charlie lives in Philadelphia, US, with his family.

After seeing the devastation in the Adelaide Hills and Kangaroo Island, he wanted to do something for his family's home state.

"He woke on Saturday morning saying he wanted to raise money for the Australian bushfire crisis," Charlie's grandfather Robert told 7NEWS.

So, the five-year-old set up a lemonade stand in front of a busy supermarket on South Street, a main thoroughfare in South Philadelphia.

Thanks to his hard work, Charlie raised $US260 for the South Australian Country Fire Service.

More than 495,000 hectares have been burnt, three lives lost and 170 homes confirmed destroyed across the state so far this bushfire season.

On Kangaroo Island alone 210,000 hectares have burnt, more than one third of the island's total area.

For Charlie, he just wanted to do his bit.

"Charlie is not a multi-millionaire, he's just a little boy who wanted to do something for his country," Robert said.

"It shows that the disaster has produced instinctual empathy."
