This is a new addition to the offer described here
Was in store today asking about the $45 deal and rep mentioned that they have just started this new deal. I believe the $45 offer is still ongoing.
The plan is described as $65pm on a 12 month contract with a $10pm port-in credit applied until recontract. 60gb data per month. $300 gift card is given on the spot.
For new or port only, not for existing Telstra customers.
