The singer chosen to belt out our national anthem at this year's Gallipoli Dawn Service says it's a huge honour.

Able Musician Rebecca Nelson will lead the anthems - with New Zealand's being sung before Australia.

She was having one of her final practices before heading off last night.

"It is a huge honour. I sang last year.

"I couldn't believe it when I got that email. It was amazing, absolutely."

She says a historian will travel with the group and teach them about the history of Gallipoli.

"So we get to walk in our footsteps of the soldiers and go pay our respects to the fallen at all of the cemeteries."
