$77 per month with half price access fee for your first month (-$35) = $1813. Handset RRP is $1149, so you're paying $664 = $28/m for 6GB of data and unlimited calls and texts, with the bonus of being able to pay your phone off across two years. Plus, you get bonus unlimited data for your first two months.
An equivalent plan on Telstra, Optus and Virgin comes out to $2376, $2040 and $2184 respectively, though you do get 8GB of data on the Optus/Virgin plans.
For the heavyish data user this is probably the cheapest way to get the GS7 on release short of buying outright, grabbing a Telstra Freedom Plus SIM and writing off your prepaid costs on a Dropbox subscription and Hearthstone packs. (which is what I'll be doing).
Alternatively, if you'd prefer the Optus network and are happy to lose 2GB of data, you can pay $13 less over 2 years ($75/m*24=$1800) and go with Virgin Mobile.
