How we picked theseWe've scored over 290+ mobile plans on everything from cost to data allowance and important features.
Our experts give each plan a score out of 10 - totally fair, with no commercial strings attached.
Optus is Australia's second-largest network, covering 98.5% of the Australian population. Optus may not have Telstra's extensive coverage, but it should be more than enough for most people.
While Optus doesn't offer the cheapest entry-level plans, it does have options that come with generous data inclusions and the ability to pay off new phones over 12, 24 and 36 months on postpaid plans.
Plus, its range of perks, including access to its 5G network and access to Optus SubHub.
Optus may be the right choice for you in the following situations:
However, it's worth keeping a couple of things in mind:
![]()
Optus prepaid plans give you the option to pay weekly, monthly, every six months, or annually, giving you control over how and when you use it. The most affordable prepaid Flex plan includes 6GB per 7 days (with data rollover up to 200GB) and unlimited calls and texts.
These Flex plans are okay since most hit the benchmark of $1 per GB, but aren't anything too special.
Its longer expiry 365-day plan offer about 30GB a month (depending on current offers) and is great value if you're willing to commit to the plan for a full year.
Things get more reasonable with Optus's 240GB for $70 plans and higher, with data getting cheaper the more you're willing to spend on your plan.

Optus has the second-largest network in Australia, narrowly behind Telstra and covering a decent amount more than Vodafone.

You can share data between Optus plans under the same account. This can be handy for families looking to bundle all their plans under one account.
With Optus, you can roll over up to 200GB on most prepaid plans.
Postpaid plans: For $5 a day, in 110+ Zone 1 destinations, you get unlimited calls as well as 5GB to use per day. Optus will automatically add 5GB for $5 when you run out of data.
Prepaid plans: For $5 per day, you can get 1GB of data, 100 texts and up to 100 minutes to use in Zone 1 destinations. Another option include 7GB for $35 over 7 days.

Can I keep my current phone number?
Absolutely. If your number is in your name, just notify Optus you want to transfer it when you sign up. All you have to do is fill out a form.
If your number isn't currently in your name (perhaps under that of a parent or partner), let Optus know and they'll give you an extra form for you and the owner to fill out.
You can also check out our guide on how to transfer ownership of your mobile number for more information.

How does data sharing work for Optus' mobile plans? We've got the full explanation.
Finder is a comparison service. We do not compare every product or every provider in the market.
We make money through commercial arrangements with some of the providers on this site. Products marked 'Sponsored', 'Promoted', 'Featured' or 'Advertisement' appear as a result of a commercial arrangement.
Our editorial content, product reviews and any 'Top Pick' designations are prepared independently of these commercial arrangements.
The default order of products in our tables can be influenced by commercial arrangements. You can re-sort or filter using the controls above each table.
Some content on this site may be generated or supported by AI tools. You should verify details directly with the provider.
Finder is one of Australia's leading comparison websites. We are committed to our readers and stand by our editorial principles.
Our comparison service does not include every product or every provider in the market. Some product issuers offer their products under multiple brands or through associated companies. Where we can, we identify the underlying issuer so you can compare like with like, but you should always check with the provider directly to confirm which brand you are dealing with.
Finder is a comparison website and an intermediary. We are not a product issuer and we do not provide personal financial or credit advice. When you click a link to a product, or apply for a product through our site, you deal directly with the product issuer. We may receive a referral fee, commission or other payment from the issuer if you click through, apply or take out a product. We describe these arrangements in more detail under 'How we make money' below.
Product features, fees, terms and eligibility criteria are set by the product issuer and may change. We rely on information supplied by issuers when we present product details on our site. Before you apply for or take out any product, you should confirm the details directly with the issuer.
We earn revenue from Finder in four principal ways:
Referral fees and commissions. When you click a product link, complete an enquiry form or apply for a product through our site, we may receive a referral fee, commission or other payment from the product issuer. We may also receive payment based on the volume of leads or conversions we send to an issuer.
Sponsored placements. Products marked 'Sponsored', 'Promoted', 'Featured' or 'Advertisement' appear as a result of a commercial arrangement between Finder and the issuer. These labels always indicate a paid placement. We do not use them for editorial choices.
Display advertising. Banner advertising, newsletter advertising and similar display ads on our site are paid by advertisers.
Content sponsorship. Some articles, videos and social media posts are sponsored by an issuer and are clearly labelled as such.
Our editorial opinions, product reviews and any 'Top Pick' designations are prepared independently of these commercial arrangements. A 'Top Pick' is an editorial choice made by our writers and editors based on the criteria described on each comparison page. A 'Top Pick' is not a personal recommendation and does not mean the product is appropriate for your circumstances.
If you would like to know whether we have a commercial arrangement with a specific product issuer, please contact us.
When products are grouped in a table or list, the default order can be influenced by commercial arrangements we have with product issuers. In some categories, sponsored or featured products appear in the top positions of the table by default, and are always labelled as such.
Other factors that influence default order include price, fees and features, and (where relevant) our editorial view of the product.
You can re-sort every comparison table using the controls above the table. You can filter by product features that matter to you. The order you see after re-sorting or filtering is not influenced by commercial arrangements.
Some content on this site is generated or supported by artificial intelligence tools, including our AI-powered assistant FinderBot. AI-generated content may contain errors. Please verify important information directly with the product issuer before making a financial decision. For more information about FinderBot, see the FinderBot Terms of Use and FinderBot Privacy Collection Notice.
Please read our website terms of use and privacy policy for more information about our services and our approach to privacy.
We update our data regularly, but information can change between updates. Confirm details with the provider you're interested in before making a decision.

Is there like any chance that I could use one of the rewards to pay my phone bill
Hi James,
The reward is a visa gift card, so you can use it anywhere Visa is accepted – including paying your phone bill! Keep in mind that there is an eligibility requirement for every reward, which can take a period of time to process, so you may not receive your reward gift card for a few months. You can check when its due to be received in your member dashboard. Hope this helps!
