Plaque about the three jetties on the Rockingham Waterfront Pioneer Rotary Walk in Rockingham, Western Australia. It reads, "The Three Jetties The first jetty was completed in December 1872, the second in 1883/4 which enabled ships up to 1000 tons to use the port. It provided berths for two ships and two cranes. The third jetty, completed in 1898, was equipped with a loading crane operated by a hand pulley."
