A Perth man is taking the fight to save his makeshift waterslide to the people, after it was revealed the City of Joondalup were attempting to shut down his backyard creation.

The controversy started when Heathridge man Luke Newton sourced the carnival slide and opened his backyard up for people to try it out.

The slide is certainly carnival-sized, and stretches over most of Mr Newton's backyard.

He posted an image of the slide on social media, and was inundated with comments ranging from people wishing to have a go themselves, asking about the legality of the slide and pitching in with ideas about how to get around local laws.
