Telstra are putting up their prices on their pre-paid plans and wish to charge me more for less service - Thanks guys!
After fighting with them for an hour, I decided it was time to finally move onto Boost and pay half the price for the same network.
Cellmate has the $300 sim discounted to $249, which is a good price.
Officeworks were happy to price match over the phone which brings this down to $236.55, which is a great price!
