Great for those already on Telstra Pre-Paid. $150 credit for $100 with 186 day expiry and 60GB included. For those not already with Telstra, you can sign up because the deal requires a BONUS $2 Telstra SIM to be purchased in the same transaction (so I do not think you will be charged for the SIM and it can be kept as a spare if you are already on Telstra).
This is my first post, and I don't care if it gets negative comments. ;)
EDIT: 23/04/2020 - Remember to grab the $2 Telstra SIM Kit first, as this deal requires that this be scanned in the same transaction. I used the self-service checkout, scanned the $2 Telstra SIM Kit, then choose the Telstra $150 Recharge from the on-screen options on the checkout display, and paid with my credit card. Your Coles receipt will show two things: 1) the "activitation" of the Telstra SIM (as it is considered to be a "gift card" on the Coles system - you will still need to actually activate the SIM via Telstra's website, a Telstra call centre or in a Telstra store), and 2) the actual $150 Telstra Recharge voucher. The expiry date appears to be 12/12/2021 - more than eighteen months away! See attached updated photo for what the receipt should look like (I have removed any personally identifying information!). :)
