It sounds to me more like Telstra's standard rip off charging. Their excess usage charge across all plans (I think it's 25c/MB though has been higher in the past) and causes all kinds of problems where people (the ones who don't understand what a megabyte is) get $1,000+ bills without really doing all that much. A lot of these cases end up going to the ombudsman for resolution, so it's a hassle for all involved.
