The Thompson Bay Fuel Jetty (often referred to as just "The Refuelling Jetty") is only a few hundred metres from the main Rottnest Island Ferry Jetty. It is also right across the grassy lawn area in front of the Dome Café.
Thompson Bay Fuel Jetty is in sight of the Rottnest Island Authority office, the Dome Café, the Quokka pub. Boats are not allowed to be roped up to the jetty for more than 5 minutes because is it being used for fuel all the time. Pick ups and drop offs therefore have to be really quick, or else the boat will have to pull off from the jetty to let others in.
