Coledale Public School students did themselves proud when their choir sang at the seaside village's Anzac Day dawn service this year.

It was the 100th anniversary of the Anzacs and the first time the school choir had been involved in Coledale RSL's Anzac service. To say thank you, the sub-branch wanted to do something special.

Coledale RSL president Jim Bates and secretary Warwick Wenham presented the school choir with a special framed poster, featuring the signatures of all choir members and the words "100 years of Anzac, The Spirit Lives 2014-2018", at a school assembly on July 27 during Education Week.

Mr Bates thanked the children for attending the Anzac ceremony.

"As I said on the day, it was special to see you so early in the morning and it must have been hard on your parents for a 5 o'clock start," he said.

Mr Bates also thanked Coledale Public School principal Tania Potter, choir teacher Tracey Connor calligrapher Lila Upton and Bola Jordan for making the plaque on the poster.

He said the RSL asked the school to take part in the dawn service.

"I thought it was pretty good, the school captains laid the wreath and three children did a speech on what Anzac Day meant to them. It was inspiring," Mr Bates said.

"When [our service] first started off a few years ago, it was 100 [people] here and 100 there, then it built up to 300, last year it was close to 500 and this year, because it was a special day, we got 1000."
