I am visiting a semi-rural area for three days in a location that is only (reliably) covered by Telstra.
However I will need some data while I am there, around 5-10Gb.
I have looked at Telstra itself, and the best option seems to be to start a 30Gb monthly data plan ($25) and then immediately let it lapse.
Are there better options? (e.g. short-term SIMs, plans via MVNOs etc)
