SKY MUSTER (SATELLITE)
The least used and known form of NBN is NBN delivered using satelite dish. This delivery type was originally built to service remote and rural locations including Norfolk and Christmas Islands where the option of Fibre was impossible due to distance and cost. Satellite is largely not an option for most of Australia NBN ready customers.
Unfortunately your choice of how you get your NBN service is largely based on where you live and what NBN offering is available in your local area. Currently as of 2017 NBN is very much an evolving platform, still suffering teething problems including well publicised issues in the media related to the speed of services on the NBN network.
Only recently has NBN started to make available true business grade options, charged at a higher price but delivering committed performance and well understood time scales of when services will be fixed if there is a failure.
