Pink Up Port Pirie will be celebrated this month with a fundraising target of $10,000.
The campaign aims to raise awareness about breast cancer while gathering money to back the McGrath Foundation.
Breast-care nurses, such as Port Pirie's Ros Mayfield, are provided by the foundation in country towns around Australia.
The month of activities kicked off last week when pink decorations, including bows, pom-poms and knitting, were put up in City Park, Florence Street, Ellen Street, outside shops and in front of Grey MP Rowan Ramsey's office.
"The idea is to 'pink up' your town to raise awareness of breast health and collect money for the foundation," Mrs Mayfield said.
"Fundraising has already begun with a lot of the schools holding events to donate money. A few businesses have been doing in-house fundraising and lots of traders have promoted awareness.
"On Friday, a cake stall will be set up on the footpath outside Bank SA. Lots of community members and Pink Up Port Pirie Committee members have baked cakes for it. We will staff a volunteer stall at the Producers' Market in Flinders View Park on Sunday, selling raffles, cakes and other items.
"Our supporters and the team will create a McGrath Life Force Symbol on the lawn between the playground and the silos at 10am that day.
"Film-maker Kim Mavromatis has offered to take video of the symbol from his drone. There will be speeches by Mayor Leon Stephens and myself then a march around the city centre accompanied by cars provided by Pirie and Districts Automotive Restorers Club."
On October 26, a High Tea with author Tricia Stringer will be held at the golf club.
Mrs Mayfield said money raised would help the foundation to provide its free service to people diagnosed with breast cancer and their families and to promote breast health.
There are 132 McGrath breast-care nurses who have helped more than 70,000 families since the foundation began in 2005.
The foundation was the brainchild of the late Jane McGrath, wife of former Test cricketer Glenn McGrath.
Breast-cancer survivor Helen Size collected prize vouchers from traders and noted a strong interest in the condition.
"I was one of the lucky ones who went through chemotherapy and radiotherapy successfully," she said.
