Optus double data is back: 80GB for $65 per month

Optus' SIM-only double data plans are back until July 8, with a massive 80GB for $65 per month deal headlining the offer. If 80GB sounds too ludicrous, you're also able to get 30GB and 50GB plans, priced at $45 and $55 per month respectively.

The plans all include unlimited talk and text, data-free music through Google Play Music and Spotify, at least 300 international minutes, and an Optus Sport subscription. 

This offer is available until July 8.

All three Optus promotional offers are pretty competitive, but there's other plans worth considering. If you don't quite need 30GB, Think Mobile will do 20GB for $30 per month, while Vodafone will do 25GB for $40 per month.
