Good deal: 80GB for $40 from Optus

Optus today rolled out a 20% discount offer on its 80GB SIM-only plan and hot damn it's a good deal. The plan now offers 80GB for $40 per month if you sign a 12-month contract.

We're Sorry

This product is no longer available

The plan comes with unlimited national talk and text, unlimited international calls to 35 countries and 4GB of monthly roaming data to use in "Zone 1" countries. (Optus Zone 1 covers most of Asia, Europe, North America and New Zealand. See the Optus website for details.) 

The plan also includes free subscriptions to Optus Sport and the National Geographic app as well as data-free streaming of Spotify, Google Play Music and iHeart Radio. The offer will last until May 5.

Optus' plan also allows you to add data-free SD streaming of Netflix, Stan and ABC iView for an extra $5 per month. But with 80GB, you probably don't need to.

Optus' deal is the cheapest SIM-only offer with 80GB on the market right now, although competitors aren't lagging too far behind. Jeenee Mobile is currently offering 82GB for $44.90 per month (with a $12.37 set-up fee) and Think Mobile is offering 80GB for only $48 per month. Both of these plans are offered on a 12-month contract.

Jeenee Mobile offers service on the Optus network. Think Mobile offers service on the Vodafone network.
