Australian Red Cross Lifeblood is calling on Port Macquarie locals to take a leaf out of Stewart O'Brien's book during this International Plasma Awareness Week.

Stewart has donated plasma 15 times, helping to save the lives of the thousands of Australians who need plasma-based medicines.

He is donating for the Port Macquarie real estate blood challenge which runs until December 31, and Lifeblood is encouraging all participants to also donate plasma.

"I didn't realise plasma was so vital to so many people," Stewart said.

Gilly Paxton from Australian Red Cross Lifeblood said Australia is experiencing a significant increase in demand for plasma and plasma products.

"Plasma and plasma products treat conditions like cancer, bleeding disorders, immune and neurological conditions, and burns.

For an appointment or more about plasma donation, call 13 14 95 or visit lifeblood.com.au.

Port Macquarie agencies donating are: McGrath Estate Agents, Elders Lifestyle Group, Harcourts Australia, LJ Hooker, Percival Property, Raine & Horne Commercial and Wiseberry Real Estate.
