Like Railway Reserve this cache is on land that used to be part of the train line running through Mackay.
This land is now one of the few places where the old line is now converted to an active park. It's now a linear park called Marryatt Street Park and is easy to access. The locals use the park as a shortcut, to take their dogs for a walk, teach their kids to ride a bike or just go for a jog or evening stroll. This park can be a popular area depending on the time of day so watch out for muggles and what their puppies leave behind. Not recommended at night.
The cache itself is a long thin rectangular sistema container with a log and a pencil and room for small swaps.
