A 12-year-old Australian boy with leukaemia has been granted his wish to “blow stuff up” with the help of Make-A-Wish Australia and the Australian Federal Police.

“Declan” was treated to a weekend he will “never forget” which included – somewhat disparately – a meeting with Prime Minister Malcolm Turnbull and Governor General Peter Cosgrove as well as the chance to detonate explosives.

Video of Declan’s adventures was posted to the ACTPolicing YouTube page earlier this week. It shows the young boy participating in a police training scenario, going on a lake speedboat ride and triggering explosives.

“Declan is 12 years old and has leukaemia. His wish? To ‘blow stuff up!’” the video’s caption reads.

“Declan is a real ‘boy’s boy’, and after spending so much time in hospital battling his illness he wanted to do something risky and out of his comfort zone.”

As part of the weekend organised by Make-a-Wish Australia, Declan also paid a visit to Parliament House in Canberra, where he was given a VIP tour by no less than the prime minister himself.
