Wanneroo Civic Choir has performed at the Wanneroo Joondalup RSL's dawn service for the past 27 years.
This year, the choir has asked students from St Stephen's School in Duncraig, Wanneroo Secondary College and Woodvale Secondary College to create a mass choir as part of the commemoration of the centenary of the Gallipoli landings.
The choir has been rehearsing since late last year, led by musical director Kent Logie.

The Challenge Brass Band, under the baton of musical director Bruce Foster, will also join the choir to perform the Australian and New Zealand national anthems and three hymns, and band member Ricky Wileman will sound Last Post and Reveille.
As part of the commemoration, Wanneroo Civic Choir members and family supporters have created more than 200 poppies for all choir and band members to wear on the day.
The choir thanked school teachers Marion Jamison, Lexie Keller, Sheila Randall and Bronwyn Matthews for helping to make the mass choir possible.
The service will be held at the Wanneroo's Memorial Park on Civic Drive from 7.30am.
