TPG has launched the Unlimited Fast NBN50 speed plan this week for $69.99 per month.
If you are an existing customer you can easily change plans by logging into My Account or calling their Change of Plan Team on 131423.
The NBN50 speed plan is offered at the same price point of their discontinued Unlimited Boost Speed Plan which was configured on the NBN25 equivalant speed tier.
For those on the Standard NBN12 or older Boost speed plans, I would definetely recommend giving the NBN50 speed plan a go. Heaps faster speeds for only $10 more a month.
