The students took to the stage at the Sydney Opera House after nearly a near of rehearsing at school.

One of the largest musical events held at the Opera House each year, students from more than 120 schools across NSW took part in the Festival performing to sell-out crowds over four days.

Tacking Point Public School performed on Monday, September 2 and Westport Public performed on Wednesday, September 4.

Teacher at Westport Public, Fleur Eichler said the opportunity to sing at the Opera House was an experience the students loved.

"Although the performance was for one day we took our 30 students down for a three day cultural experience," Ms Eichler said.

"The opportunity to sing at the Opera House is one of the greatest opportunities music students can take part in at primary school and all our students had a great time.

"The opportunity to sing with a 700-strong member choir is extraordinary but to experience the ensemble and band in that kind of a setting is also so wonderful."

Year five student Emily Edenborough said she had a great time in Sydney.

"We got to stay in Sydney for a few days which was really good," Emily said.

"We got to go to the aquarium and walk across the Sydney Harbour Bridge as well as sing at the Opera House.

"At the rehearsal they put on a light show and showed us what the lights could do which was amazing.

"It was so much fun."

Minister for Education and Early Childhood Learning Sarah Mitchell said performing at the Sydney Opera House is a moment children will remember for life.

"The opportunity to showcase your talents in Australia's greatest musical home is a huge honour and I'm so excited for all the NSW students performing during the festival," Ms Mitchell said.

"This government is passionate about the Arts and so are NSW students, with over 520,000 students involved in Arts Unit programs so far this year."

The Arts Unit's Kindergarten to Year 8 Music Officer, Ian Jefferson, said the Festival is a unique opportunity to showcase the talent in NSW primary schools.

"Performing at the Opera House is a thrilling musical experience for these students, and for some of the regional students it may be their first visit to Sydney," said Mr Jefferson.

"The students have been chosen for their talent and passion for music, and should be very proud of what they have achieved.

"Congratulations are due to them and all the teachers and other staff responsible for bringing everything together for such a major event."
