CAREFLIGHT is calling for community volunteers to participate in the MAYday charity event on May 18.
Volunteers will be collecting donations at 29 train stations across Sydney including Parramatta, Granville, Lidcombe, Westmead and city stations.
If volunteers are not able to help collect at train stations they can choose their own location, such as at work, at sport and recreational events or at their favourite cafe.
CareFlight community engagement co-ordinator John Ebbott said participants will receive a t-shirt, a badge and collection buckets on the day.
"The money raised will help our crews and doctors respond to emergency calls of severely injured children and adults, as well as provide medical research and training for our staff," he said.
Volunteers can register at mayday2012.gofundraise.com.au or call 9843 5100 for more information.
