Australian coastline


I am planning a circumnavigation of Australia by sailing boat. I'm currently with Telstra as there coverage was superior at the time I signed up. What is Optus coverage like today, will there be many dead spots arround the coast. 


Re: Australian coastline


Yes there will be lots of dead spots particularly around the top end of Australia. Telstra will be better than Optus but the only safe option for you is a satellite phone.



Re: Australian coastline


That's a super exciting trip you have planned @Harro56,


I'd definitely take up the advice @Withy has offered up. 


You can purchase a SatSleeve+ through Optus. It's a costly option, but perfect for this sort of thing. 

  • Easily turn your compatible smartphone into a satellite phone
  • Let's you walk and talk, even when you're out of mobile coverage
  • Clips onto your smartphone like a case, with a universal adaptor to fit most Android and non-Android smartphones (excluding Windows)
  • Use the SatSleeve+ and your phone together to make calls and SMS through the SatSleeve app
