The original timber Jetty was constructed, using convict labour. Exposed to North-Western storms, it was1400 feet (426.7m) from it's original root, and 7 feet (2.13m) depth at its head. It was continually lengthened until 1952 to 4600 feet (1.5km).
Divers using air pumped from above were employed over the years for maintenance below the water line. Prior to that, all cargo (mainly imports of farming implements, foodstuffs and clothing with exports of sandalwood and jarrah timbers) was 'lightered' (use of small boats) to anchored ships.
