Banksia Grove resident Katey Higgs said her son was always so excited about bin collection days that he could not fall asleep the night before.
Every Friday, he helps take the bins down the driveway before the trucks arrive.
“Our neighbour noticed how much he loves watching the trucks in action and she now pays him 10c a bin to put her bins out the night before,” she said.
“The arrival of the trucks is the highlight of his week.”
The neighbour contacted the City of Wanneroo’s waste services department to ask if they could offer Harrison a tour of the trucks.
Waste operations supervisors Dan Vicencio and Clyde Leach obliged and a thrilled Harrison visited the Ashby Operations Centre recently.
“He was so excited, he is still talking about it every day,” Ms Higgs said.
She said Harrison’s fascination with garbage trucks had begun when he was two-and-a-half.
Harrison’s grandparents came to stay with him while Ms Higgs spent time with his younger brother Finlay (2) in hospital.
“They developed a ritual – he takes the bins out on Thursday and waits and watches when the bin men come and pick it up,” she said.
Harrison has a large collection of toy garbage trucks, is always putting rubbish in the bin at home and knows what needs to be recycled.
“We’re always saying that he’s a future garbo,” Ms Higgs said.
“It (the tour) meant quite a lot to me.
“I had to be apart from him for about a year and seeing him being treated like he was so special, it meant a lot.”
