Optus $2 days to $3 days (unlimited internet)

[Guiseppe]

Optus does have a 80Gb 12month deal out there for $45 a month on 4G, but the only catch is, if you go over the 80Gb, they charge you $10 per Gb.
Not sure if you can opt out of that? Or if its an automatic charge.

I am also very leery of that so am staying away.
