Horsham Aquatic Centre celebrated Australia Day with a pool party on Saturday.
Centre manager Steve Clark said 200 children and 150 adults attended the day.
"I was very pleased with the turnout," he said.
"It was very encouraging for future events."
Mr Clark said it was a fun event and money raised would support the YMCA Open Doors program.
"The Open Doors program is about assisting those without financial standing to attend our programs and services," he said.
Activities for the day included inflatable zorbs and obstacle courses.
"We had the Country Fire Authority spraying water, party games, a fashion parade and generally lots of fun," Mr Clark said.
He said there were also bombing and diving competitions throughout the day.
Horsham Rural City Council donated Australian flags and tattoos for the party.
Horsham Salvation Army cooked a barbecue.
YMCA Open Doors representative Barry Furness attended the event.
"What made Horsham stand out was the community support received from businesses and organisations such as the CFA and Salvation Army," he said.
Mr Clark thanked his staff, volunteers and well-behaved patrons.
He said it was the aquatic centre's fourth pool party in the past 12 months.
"It is definitely something we will be doing again very soon," he said.
