Among those who went along were Nevaeh Scott, 7, Kaydince Keogh, 8, and Nadya Scott, 9, who tried on the uniforms.
"Kaydince is part of the St John youth group, so we took a friend of mine and her daughters. Now she wants to become a volunteer," said Chrissy Jenkins.
"Kaydince showed them what St John was all about, she was very excited. They loved it - it's not every day you get to try on these uniforms. They all learned CPR - it's a handy skill to have.
"My friend was very surprised at what was on offer, so now she's going to one of the seminars on how to become a volunteer."
