In June 1910 Hayles was granted another permit to construct a jetty in Picnic Bay. Although it is unclear whether the second jetty was constructed in addition to the one constructed in 1900 or to replace it, a letter dated February 1917 from the Townsville Harbour Board to the Marine Department acknowledges the presence of two privately owned jetties in the bay. In 1911, Hayles' hotel was destroyed by a fire and a new hotel began construction. At around the same time, Hayles further expanded his business on Magnetic Island launching further tourism ventures in Nelly Bay, Horseshoe Bay and Arcadia. In June 1920 the Townsville Harbour Board were vested control of the jetty at Picnic Bay, as well as those established in other bays.
