Whatever you do, don't choose NBN satellite ...
The NBN SkyMuster service (in my experience of about 6 months) is just totally awful. The NBN/Ericsson engineers should hang their heads in shame. I kept a diary of downtime, and every day I could count on something bad happening, usually in the middle of an online banking session
or YouTube video. Any rain in the area, or a lightning storm within 100km of my home, (or near the region of the sat receiving station - eg Kalgoorlie) meant total drop out, in my experience sometimes for hours - or even a whole day recently.
So I switched back to Telstra Mobile data. Signal strength isn't ideal, but 4G works, and it is such a relief to have stable Internet again!
