Mills flew in from the United States while the NBA's All-Star break was being held.

The Canberrian headed straight to the coast to try and do his bit for bushfire ravaged communities along the coast.

There was no big fanfare, no big announcements - he just arrived, did his thing and supported the various local communities he visited.

Undoubtedly one of Australia's highest profile sporting stars, Mills dipped into his own pocket during his short trip, buying local, supporting those communities that have been decimated by the horrendous fires.

After visiting Mogo, Wallaga Lake, Cobargo and an animal sanctuary at East Lynne, he continued his journey up the Princes Highway towards the Shoalhaven.

He stopped off at Conjola chatting to locals, signing autographs, while at Batemans Bay he served at a local supermarket, even shouted locals' groceries.

His visit did get out on Twitter. The man, who has more than 400,000 followers, took to his own page to document his journey, and despair at what he was seeing.

He also passed on that important message that so many local businesses, tourist operators and community in general has been spreading for months - buy local, support local.

He said "how can I help?" is one of the most common questions people ask him when talking about the Australia fires. His simple answer - shop local.

"The best thing you can do to help these communities is to visit them, stay in local hotels, eat at family-owned restaurants and shop local stores. The bushfires have severely affected tourism in smaller cities of Australia. Small business, big impact," he tweeted.

His visited included a stop off at Martin's Orchards at Jerrawangala where he purchased all the remaining nectarines they had, filling the back of two utes before stopping at Nowra High School to hand them out and chat with staff and students.

Mills is the latest of a number of stars who have visited fire ravaged areas. Human Nature put on a concert at Milton Public School, while legendary Aussie vet Dr Harry Cooper stopped in at Malua Bay on Wednesday, to name just two.
