You can access Optus cashback offers and discounts across several services, including prepaid and postpaid SIM-only plans, NBN plans and devices. Here's a rundown of what's up for grabs.

Right now, when you sign up for an eligible prepaid or postpaid SIM, or phone plan through Finder, you'll get a Finder Reward in the form of a Visa gift card worth up to $200.

This is in addition to offers from Optus itself, which we run through further down.

While there aren't any coupon codes available this month, these deals offer the same bang for your buck (if not more).

Optus discounts on prepaid SIMs

Optus is running bonus data offers on most of its month-to-month and long-expiry prepaid plans.

There are also a couple of discounts. For example, its $39 28-day expiry plan will cost you just $13 on activation.

You will also receive 45GB on each of the first 3 recharges before the allowance drops down to 25GB ongoing.

When you sign up through Finder, you can score $100 cashback on its 365-day prepaid plan, $75 on its 186-day expiry plan, or $50 on its monthly prepaid offers.

Optus discounts on postpaid SIM plans

Optus is offering a $10 a month discount on its 360GB Promo plan for the first year. You'll pay $69 a month for the first 12 months, then $79 ongoing.

If you don't need that much data, you can still save with a $15 monthly discount and bonus data on Optus's $55 and $65 plans for the first year. The $55 plan jumps to 100GB for $40 a month, and the $65 plan to 250GB for $50 a month.

These plans also include a $10 monthly credit for 12 months to use on subscriptions like Netflix and Amazon Prime via Optus SubHub.

Regardless of what postpaid SIM plan you choose, you'll get a $150 reward when you sign up through Finder.

Optus discounts on phone plans

Optus is running device offers across popular phone brands, including Samsung and Google.

Get a bonus Galaxy Tab A11+ 128GB in Grey when you buy any Samsung Galaxy S26 model on a 24- or 36-month phone repayment plan.

For Google phones, you can get a $500 discount on the Pixel 10, and $750 off on the Pixel 10 Pro, both on 24- or 36-month plans.

Plus, you can get a $200 reward when you sign up to an Optus phone repayment plan through Finder.

Optus NBN discounts

You can save up to $10 a month for the first 12 months on Optus's NBN promo plans (NBN 100 and NBN 500). These plans will cost you $109 a month for the first 12 months. After that, the price will jump to $119 a month.

You can also bundle your internet plan with an eligible mobile service to get $15 per month off for 12 months.
