As one of Australia's 'big three' telcos, Optus firmly holds its position as the second-largest provider between Telstra and Vodafone. It's not as aggressively priced as Vodafone, but Optus maintains a strong balance of cost, data and coverage, making it a compelling choice for many Australians. In fact, the latest reports by Opensignal once again crowns Optus as Australia's fastest mobile network for both overall download speeds and 5G performance.

The indelible memory of the Optus data breach and nationwide network outage remains. However, according to the Telecommunications Industry Ombudsman’s (TIO) Quarter 3 2024-25 complaints data, Optus' complaints are down 6.7% quarter on quarter, while Telstra and Vodafone saw increases.

For those satisfied with their current smartphone, Optus' range of prepaid and SIM-only plans offer attractive value. Currently, Optus plans start at AU$55 for 50GB, AU$65 for 200GB and AU$85 for 400GB. However, right now, you can get a 20% discount on the first 12 months of its Small and Medium Choice plans with the code YES20.

If you're looking to pair one of the best phones or best cheap phones with a SIM plan, Optus remains a strong contender. To help you navigate the options, we've gathered all the best deals and offerings on the most popular handsets and SIM plans below.

Noteworthy Optus deals

We'll get to the best Optus plans in a second. First, here are some deals currently available through Optus on some of the best phones right now.

Best SIM-only Optus mobile plan

Optus Small Choice Plus | 50GB Data | AU$44p/m code YES20

Optus Small Choice Plus | 50GB Data | AU$44p/m (for 12 months with code YES20)

The usual AU$55 p/m price of the recently increased Optus Small Choice Plus plan slots it in between Vodafone and Telstra, but Vodafone's discounted small plan costs just AU$39. Right now, though, this 20% discount on Optus SIM plans brings the price of this small option to just AU$44 for 12 months – so it's much easier to recommend. You get the fastest 5G connection in Australia, plus 50GB of data each month, unlimited national talk and text and unlimited international talk and text to 35 destinations.

Total cost over 24 months: AU$1,188
