It started when he was picked up at his home in Nornalup in a police car with its siren blaring and lights flashing for the trip to Albany Leisure and Aquatic Centre for a party.

The cold weather was quickly forgotten when he was met by Make-a-Wish volunteers dressed in pirate costumes for the party with friends and family.

“He came out of the house with his hands in the air, he was so excited,” Caelen’s mother Tash said.

“It was a super surprise. He didn’t know about the police or the gifts.”

Caelen was diagnosed with a Wilm’s tumour, the most common form of childhood kidney cancer, and in 2006 spent eight months in Princess Margaret Hospital where it was removed.

It was there his parents applied for a Make-a-Wish as “he wanted to go somewhere exciting,” his mother said.

Caelen’s smile is expected to continue well past this weekend when he travels with his parents to Queensland for the main part of the wish to spend some time at Gold Coast theme parks.

“Everything is alright with Caelen now,” Mrs Minchin said.

“He just had his three-month check-up and he can just get on with his life.”

Caelen was met on Saturday morning by Sgt Paul Morrell from Walpole Police who volunteered his time to give Caelen, his mate Joel Weir and father, Paul, the ride of their lives to Albany.

On the way, Sgt Morrell had to stop a driver for speeding.

Make-a-Wish Albany organiser Sherri Willock said there were about 20 people in her group who enjoyed providing surprises for deserving children.
