The service called out for volunteers earlier this year to help patients from as far away as Young travel to the Riverina Cancer Care Centre in Wagga for treatment.

Cancer Council's local community programs coordinator Catherine Goodall said she was "blown away" by the response from the community.

"We actually had to start turning people away, which we don't like to do, but we had such a huge response," she said.

Ms Goodall said there was a "huge need" for the volunteers, with two cars going out most days to collect patients.

"We know that there's people out there in the community who might not have family around or don't have any family," she said.

Wagga man John Gray answered the call and is now one of 16 drivers who manage trips across a 200 kilometre radius, five days a week.

Mr Gray, a retired farmer and former Wagga RSL board member, said he had done about four trips so far with "people from all walks of life" receiving cancer treatment.

"I've really enjoyed it so far. And I've really enjoyed the people we're trying to look after," he said.

"They're so nice and they're so grateful. They shouldn't be, but they are.

"And t's so nice to hear them talk so positively about the treatment they get at the Riverina Cancer Care Centre."

Mr Gray, whose own wife was successfully treated for cancer in Sydney before the RCCC opened in Wagga, said being a volunteer driver was "a great listening role".

"Just to deal with people who really appreciate what's happening for them even though they're in a rotten stage of their lives," he said.

"It's just so nice to hear them be so positive. It's a good life learning experience."
