The group are taking part in Dry July, and Lourdes health service manager Steve Evans said he was confident they would be successful.

“My dad passed away in 2014 of cancer and the hospital he was in had a project funded by the Dry July movement. That sort of gave me the idea to do it,” he said.

Tamara Hollman was also motivated by her family.

“My son was diagnosed last year with cancer. He’s okay now but it was pretty intensive for the last year,” she said. 

“There’s a lot raising money for certain cancers but they’re generalised, they’re for certain cancers. This is something for everyone who has cancer.”

Ms Hollman said she wouldn’t be tempted to drink as she would be thinking about what cancer patients go through.

Funds can be donated through the Dry July website.

“They can pick a team or donate it to one of us- it all goes to the same charity,” Mr Evans said.

The money raised from Dry July has funded a range of services like a free wig library in Royal North Shore Hospital, transport to treatment services in Lithgow and chemotherapy chairs at the Maccarthur Cancer Therapy Centre.
