Prince Charles is making a donation to the Australian Red Cross to help it support people affected by the NSW bushfires.
In a message sent to NSW Rural Fire Commissioner Shane Fitzsimmons Prince Charles said he had the "great pleasure" of meeting some NSW volunteer firefighters at Sydney's Bondi Beach last year.
"I just wanted you all to know that you are very much in my thoughts as you battle courageously against such appalling bushfires around Sydney."
Prince Charles said he and his wife Camilla "greatly admire the selfless service you provide in such incredibly dangerous and distressing circumstances and our hearts go out to all those - including firefighters - who have lost their homes in this terrible conflagration".
Scores of residents have evacuated their homes in the mountains west of Sydney. Seventy-one blazes are burning in the New South Wales state around the city, including 29 that are out of control. The region lost more than 200 homes to blazes last week.
The Queen last week sent a personal message to the Governor of NSW, Marie Bashir, expressing her sympathy over the fires which last week destroyed nearly 200 homes at Springwood in the Blue Mountains.
