Zoleo Satellite Communicator
I use a Zoleo and find it useful, I hope you might too. The user experience is very good. Simple and uncomplicated. Basic monthly charges are AUD32 for 25 messages, AUD0.65 for extra messages, AUD8 extra for 6 minute location share, suspend for AUD6.5 per month. There is an AUD40 activation fee. Less limited plans are extremely competitive. See plans here
