Paddock Bomb: Clancy of the Outback series

In this book, Dad's old car has to be taken off the road, so Little Bill decides it could be Clancy's 'paddock bomb'. Meaning he was going to drive it around the farm. Meaning she was going to teach him to drive. She makes Clancy sit in a baby booster seat so he could see over the steering wheel, and that was just the start of his humiliation!
