Yes. Given its size and geography a Sat Nav aid is recommended although your smart phone’s Maps app will likely provide a good alternative where there mobile phone coverage. If you are visiting from overseas consider a local data plan as map apps will consume data which can be expensive when using data roaming. If your travel plans are in the remote Outback consider a satellite phone or EPIRB (Emergency Position Indicating Beacon) as mobile phone coverage will be limited. EPIRB’s can be purchased in Australia from as little at $350. Talk to your chosen rental company if your plans take you to remote parts of Queensland.
