Was just in store signing up to the $69 Telstra Plan with $500 gift card deal when I happened to ask if they had any NBN deals on the go.
Scored an extra $200 Gift Card for switching over my NBN connection to the Telstra month-month plan and got the same deal currently on Telstra’s site ($0 install, $10 off for 12mths).
The deal is on both the $90 and $110 Telstra NBN bundles (bringing the monthly cost down to $80 and $100 respectively).
Deal is also available directly through Telstra (with Telstra Plus Points… not sure if the JB plan will come with these or not but I'd prefer the $200 GC anyway): https://www.telstra.com.au/internet/nbn
$90 plan (down to $80) is NBN 50 Standard Plus
$110 plan (down to $100) is NBN 100 Premium
Not sure the exact end date but it looked like 29/09 when he pulled up their internal offers page.
