PORTLAND North Primary School celebrated it birthday on the weekend in style with a few trips down memory lane, and a Saturday fete involving pony rides, jumping castles, history displays and lots of music.

An estimate of 500 parents, children, friends, past students and past staff showed up to the school grounds on Saturday to commemorate the schools long run of 150 years.

The school was established in 1873 as Cockatoo Valley State School and has since been displaying the same community spirit it prides itself on.

“We had an amazing day, it was so successful,” principal Cate Elshaug said.

“We're very proud of all the kids and all the teachers. A huge amount of work went into getting prepared and we've had some amazing feedback.

“Past staff and past students really went out of their way to come and congratulate us on the preparation we did and the exhibitions that we created.

“There were a lot of people who'd been there in the ’30s, ’40s and ’50s, and it was great to have them there.”

A few past students, some aged into their 90s, attended a reunion on the Friday afternoon and then came to the event the next day for the celebrations.

As the day was a combination of their annual fundraising fete and school concert, students oversaw their own game and food stalls to raise money for upcoming grades five and six camps.

Ms Elshaug said locals particularly enjoyed school history exhibition, as it was packed all day with people strolling through.

“The art exhibition was very popular and the children’s history inquiry exhibition was really well attended,” she said.

“Then the rest of it was other fun stuff, pony rides, raffles, jumping castles, cake stalls and competitions.”

Emergency service vehicles dropped by and had a competition to see whose siren was more exciting and there was another visit from the Portland Secondary College (PSC) band.

At the end of the day, students held a musical performance and played two songs, then lead by the PSC band who included past North Primary students.
