Storm-surge flooding arrived at nearly the same time that astronomical high tides also lifted ocean levels.
The storm also dumped as much as 18.5 inches of rainfall, triggering local flash flooding inland as well.
Dylan made landfall near Hideaway Bay, between Bowen and Airline Beach, about 3.30 a.m. local time.
Residents of the coastal hamlet of Hideaway Bay awakened to find only limited damage from what Australian meteorologists referred to as a Category-2 cyclone but was internationally catagorized as only a tropical storm.
Queensland Premier Campbell Newman expressed relief that the damage appeared to be so light.
A day before Dylan arrived, huge waves of up to 30 feet in height offshore tossed two boats in Bowen's fishing fleet into each other before smashing the vessels onto the coast.
Drought-stricken Queensland farmers and and ranchers inland were welcoming the remnants of the cyclone, expected to deliver desperately needed rain and ease the parched conditions gripping two thirds of of the state.
