A Port Lincoln woman will give back to an organisation that helped her son and her family by taking a big plunge on October 18.
Grace Kemp will take part in the inaugural Adelaide City Plunge, which will involve 100 participants abseiling 132 metres down one of Adelaide's tallest buildings, the Westpac building.
As a part of the team 'EP Fearless Foursome', Mrs Kemp will abseil alongside sister Kazia Kemp, mother Liz Gloyne and friend Karen Milnes to raise money for Ronald McDonald House Adelaide.
Mrs Kemp said Ronald McDonald House had been a great help to her family whenever they had to travel to Adelaide for her son Jack's treatment for clear cell meningioma.
She said she signed up around the time of Jack's fifth surgery.
"Because so much control was taken away from me regarding Jack and his surgery, I refocused my energy to something I could control by signing up for the Adelaide City Plunge," she said.
"I've always wanted to do something for the house and I felt this was the perfect thing to do to raise money, and I'm a bit of an adrenaline junkie."
The team had raised $6708.34 as of October 14, and people can donate through the team's Every Day Hero page.
Mrs Kemp said she was amazed by the constant support for her family and for Ronald McDonald House, which had supported her family since 2015.
"For other families like our family, Ronald McDonald House is home away from home," she said.
Others taking the plunge include Adelaide Crows AFLW coach Matthew Clarke, Port Adelaide Football Club chief executive officer Keith Thomas and journalist Kate Collins.
Also among the participants is 85-year-old Colleen Billows, who has volunteered at Ronald McDonald House for 20 years.
"If she's taking the plunge then I can," Mrs Kemp said.
