Optus has teamed up with Flybuys to offer an exclusive range of SIM-only plans that represent pretty good value. These plans are still delivered by Optus, you'll just need a Flybuys account to nab them. The full range is as follows: 

  • $35 per month gets you 40GB and 10,000 bonus Flybuys points
  • $45 per month gets you 60GB and 15,000 bonus Flybuys points
  • $65 per month gets you 100GB and 30,000 bonus Flybuys points

The plans also include unlimited talk and text and Optus Sport, but no international inclusions. These plans are available until September 30. 

The $35 per month plan is the clear standout. For comparison, spending $39 per month on Optus only gets you a 10GB allowance. This plan doesn't include Optus Sport either. 

The comparison is a little trickier when it comes to the other two plans. Optus will charge you $49 per month for 60GB, so you'll save $4 per month by going with the Flybuys promo plan, but will miss out on international calls. And Optus normally charges $59 per 100GB on its standard plan, so the Flybuys option works out to be more expensive. We wouldn't recommend it unless you really want those 30,000 bonus points. 

There are a few other catches to be aware of. The Optus Flybuys plans require you to commit to a 12-month contract, whereas Optus' SIM-only plans are contract-free. Optus' SIM-only plans can also be paired with a new device, but the Flybuys plans can't be. You have to be a Flybuys member to get these plans, but registering for the program is free

For reference, here's a look at what other SIM-only plans between the $30 and $40 mark look like.
