With a sharpie mark on the inside of each colorbond post the position of your bottom rail which will correlate to the height of your fence and the height of your retaining wall i e for 600mm high retaining wall mark 600mm below your bottom rail mark.
We use h4 50mm x 200mm x 2 4m treated pine sleepers for the panelling and 125mm x 75mm h4 treated pine posts for the build.

Set the ground pegs about 500mm at each end of the retaining wall and then connect.
