Brisbane Waters Brass Band from central coast NSW and Port Macquarie Hastings Municipal Band are combining their music from 7pm on May 29 at the Laurieton United Services Club.

Municipal band president Leanne Howlett said proceeds from the concert will be donated to the Red Cross to assist in flood relief.

"Late last year the brass band contacted us to do a fund raising effort for the local area, but due to COVID they couldn't come. They contacted us again this year and we thought it would be appropriate to fund raise for the floods," Ms Howlett said.

"We had a few band members affected, one member lost their house and it's a cause that is close to home.

"Laurieton, North Haven and Dunbogan were some of the areas hardest hit and so it seemed important to hold the event there.

"Support and funding is starting to run out for flood victims at the moment so we thought it would be appropriate for us to put a concert on and try to raise as much as we can for the local area."

The brass band is providing 23 members and the municipal band providing 22 members on the night, according to Ms Howlett.

The event is supported by Port Macquarie-Hastings Council and LUSC.

Tickets are available at the door, $10 for adults and $5 for under 16s.
