It's way past Bunnings.
You carry on past the Bunnings car park, then past the shopping building on the left, and then turn left at, what looks like, the service entrance for the shopping centre. You cross the little roundabout and carry on around the back of the building until you come to another roundabout and a sign showing a 'No Entry' to Bunnings. You take a sharp (switchback) left up the ramp and then turn sharp right at the top of the ramp.
