After weeks of waiting for the finishing touches to be made on the new climbing frames, students raced to be the first one to climb the five metre high climbing ropes and run and jump across the rest of the equipment, and nothing in the world could contain their excitement.

Fifteen volunteers from had Cadia teamed up with students and teachers to install the playground and help place the soft-fall material around the equipment.

Students all had a hand in helping on Monday, including Chase Dixon.

Before it opened, the year five student said he was excited to give it all a whirl, especially the climbing frame which was his favourite part of the playground.

"We play skip and run around now and it's a bit boring ... but this will be good," he said.

Glenroi Heights principal Liz Beasley said the new playground would be a massive boon to the school.

"The kids are going to love it, we've got a really big playground but not a lot of equipment in there so we feel this is going to be really valuable for the kids," Mrs Beasley said.

"It's a nature type area as well with a bit of climbing and a bit of trees coming over."

Mrs Beasley said the school had been gunning for an expanded play equipment area for nearly five years, and this important step was the first of many, with a multipurpose court and bike track to come.

Cadia general manager Peter Sharpe said there had been a great opportunity for the company to get involved after the school reached out, and many of the workers helping had given up spare time to be there.

The company had given $1000 plus materials and additional funding.

"By offering manual labour, materials from our mine site and additional funding for plants and materials, the Schoolyard Blitz has allowed the project to be completed sooner than anticipated and has also given the students ownership of the project by allowing them to be involved in its development," Mr Sharpe said.

"I'm proud of the team and the people who've donated the time to such a worthy cause. You've only got to look at the kids' faces, even building it let alone playing on it.

"Every single student has had the chance to help."

He said it was "wonderful" to witness students' excitement first-hand.

"To be able to put a smile on kids' faces is the best gifts we can give," he said.

"It really is the best part of the job to get around with the community. we're always proud to be partnering with such worthy causes."
