Pink Up Port Pirie campaigners looked skyward on Sunday.
As they stood in formation to depict the McGrath Foundation symbol, a drone buzzed overhead.
Kim Mavromatis, of MAV Media SA, captured the moment with his aerial camera.
It contrasted with last year when a similar exercise was called off because of a storm.
This year the campaigners staffed a stall at the Producers' Market that morning and ran a cake table outside Bank SA on Friday.
The idea was to raise money for McGrath Foundation in the Pink Up Port Pirie promotion this month.
The foundation provides a free breast-cancer service around the nation from nurses such as Port Pirie's Ros Mayfield. Mrs Mayfield, Trish Rollins and Judy Baldwin led a march around a city block after the drone-picture.
They held a banner saying Pink Up Port Pirie Breast Aware. About 25 marchers waved placards and wore pink ponchos.
Pirie and Districts Automotive Restorers Club provided a cavalcade of rare cars to bring up the rear of the parade.
The cars included a black Pontiac driven by Mayor Leon Stephens. Earlier, Mr Stephens had pledged to find the culprits who tore down pink bows from palm trees in Florence Street.
"The bozos took down the bows. We have about 80 security cameras around town so we will look into that," he told the crowd. He said the foundation had 132 breast-care nurses nationally to help "incredibly brave" women.
"Thank you and God bless you for all the work you do," he said. "May the event be successful and I thank you from the bottom of my heart."
On October 26, a fundraising High Tea will be at the golf club.
