This year we celebrate 10 fabulous years of the iconic Marilyn Jetty Swim. Our Marilyns first took to the seas in 2014, and, since then the event has grown into an iconic annual event which to date has raised an incredible $820,000. We take a look back at how it all began and what this incredible event has achieved over the past 10 years.

Like so many others, founding Marilyn Sarah Tinney, first turned to fundraising for Cancer Council SA in 2006 when she found out that her mother, who lived in the US, was diagnosed with uterine cancer. From the first day of her mother’s diagnosis, Sarah pledged to help raise money to cure cancer in her honour.

“I felt helpless because I was so far away, so fundraising was my way to support her from across the globe. After she passed away in 2007, supporting people impacted by cancer became even more important to me,” Sarah said.

Sarah said the idea for the Marilyn Jetty Swim started as a light-hearted conversation with some of the women at the Brighton Surf Lifesaving Club who suggested she take part in the Channel 7 Brighton Jetty Classic—South Australia’s largest open water swim—in the name of fundraising.

“They knew I was passionate about supporting Cancer Council SA and suggested I take part in the swim all in the name of fundraising,” she said.

“I’m not athletic but agreed to do a swim out to the jetty with a floaty on two conditions—I’d make it comical by dressing like one of the most iconic women to grace our screens and I’d be joined by lookalike decoys so people couldn’t identify me swimming!”

A handshake sealed the deal and the Marilyn Jetty Swim was born.

“It was only months later, while feeling reluctant, that I called my friend with the intention of pulling out of the stunt. When she told me the shocking news that she’d just been diagnosed with breast cancer and I knew there was no turning back,” Sarah said.

That first event saw 50 Marilyns participate and raise over $26,500. Since then the swim has grown year on year, with the 10th anniversary in 2023 set to be the Marilyn’s biggest year yet.

The event is now an iconic part of the annual Channel 7 Brighton Jetty Classic which sees over 300 South Australians swim or paddle 400 metres around Brighton Jetty—dressed head to toe as 50’s icon Marilyn Monroe.

The blonde bombshells work tirelessly in the lead up to February every year, holding cinema nights, sausage sizzles, high teas and pamper events, as well as raffles, casual days and lunch tours—whatever they can to raise funds.

“Each year we have a fabulous time knowing that we’re making a big difference. It’s really quite spectacular to see more than 300 Marilyn lookalikes plunge into the ocean, paddling around the Brighton Jetty,” Sarah said.

“With every fundraising event I’ve done, particularly the Marilyn Jetty Swim, my mum is in my heart. I know I’m doing something to help beat cancer in her honour and it’s given me incredible empowerment to turn my grief into action.”
