About Optus

Optus is an Australian telco selling mobile SIM plans, nbn home internet, phones, tablets, watches and entertainment, with prices in AUD.

Before you chase a headline phone price, check the payment term. Device discounts paid off over 24 or 36 months disappear if you cancel the plan early.

Optus belongs to Singtel and trades as Singtel Optus Pty Limited, serving personal, business and enterprise customers. It promotes its mobile network with Opensignal results, citing a May 2026 report that named it the country's most awarded mobile network, and offers 5G in selected areas. Accessories are sold alongside devices, and the site also handles recharges.

Support is available 24/7 from human tech staff online or through the My Optus app, and there is a store locator for walk-in help. Customers can trade in an eligible device for a gift card. The company publishes a payment assistance policy for people under financial strain, plus support pages for disaster relief and for anyone affected by domestic or family violence.

Does Optus have a student discount?

Yes. New mobile services can get 200GB for A$39/month for 12 months under the student offer.

How to use a Optus promo code

  1. The Optus offers on the pages read are plan and device deals rather than codes, so the saving comes from picking the right plan when you sign up.
  2. A customer switching to Optus is offered 100GB for A$39/month for a year.
  3. Students starting a new mobile service get 200GB for the same A$39/month for 12 months.
  4. On home internet, the nbn Promo Plus plan runs at A$69/month for 6 months.
  5. Read how long each promotional price lasts before you commit.
  6. A phone discount spread over 24 or 36 months goes if you leave early, so match the term to how long you'll stay.

More ways to save at Optus

  • Trade-ins are the other big lever, since handing in a device earns a gift card advertised at up to A$1500.
  • Phone deals on the site include 50% off selected Samsung Galaxy and Google Pixel handsets, and up to A$780 value on an iPhone plan.
  • Check whether a phone discount is paid out over the plan term, because any discount paid over time is lost if you cancel early.
  • If money gets tight, the financial hardship program offers payment assistance at no charge.
