170

Costs $6 after cashback for 75GB 28-day SIM. Previous offer was $4 after cashback for 50GB.

  • 5G with International calls.
  • Boost has reduced the price from $39 to $13 & increased data to 75GB for the 25GB 28-day prepaid SIM.

SIM includes first recharge.​ 75GB on first 3 recharges for new activations. 25GB from 4th recharge. 28 day expiry. All for use in Aus. Incl. international calls.

Also available: $245 (after $85 cashback) on 365GB 12-month prepaid SIM for $330 posted here.

My notes:

  • Please note that letting the number expire and not recharging is eligible for cashback.
  • Please don't deactivate or port away until you receive the cashback. Deactivate means requesting Boost to remove the number.
  • Terms and conditions are from Telstra/Boost and apply to all cashback providers. Confirmed with the rep tightarse here, here and here.
  • Cashback is on the purchase of the physical SIM only. You can convert to eSIM after you have received the physical SIM. Activate the physical SIM first, insert and then convert to eSIM.
  • If you're a current Boost customer, you will need to port out into another provider (e.g. $2 Telstra SIM) and then port back into Boost. Please see the steps in my comment here.

TA's Tracking Tips:

  • Prior to using TopCashback, disable/remove all 3rd party plugins (AdBlock, uBlock, Pi-hole, Honey, etc), VPNs, avoid browsers such as Brave and close any additional browser tabs.
  • For iOS device: Apart from ensuring you’re not using an AdBlock app for Safari, the most important one is to ensure you have ‘Prevent Cross-Site Tracking’ turned off (see here).

What will stop me getting my cashback

  • SIM must be activated within 30 days of purchase, and must not be deactivated until your cashback is payable. If the SIM is deactivated prior, Boost may decline cashback.
  • Multiple SIM purchases need to be made as separate transactions. If there is more than one SIM in an order, it will result in an untracked purchase and the purchase will be ineligible for cashback.
  • Cashback is ineligible on eSIMs, recharges, phones, bundles, accessories, $2 SIMs.
  • Cashback is ineligible on use of any codes not approved and posted by TopCashback.
  • Cashback is ineligible on use of gift cards for payment and/or purchase of gift cards.
  • Cashback is ineligible on purchases made via the retailer's mobile app.

What else is essential

  • Engaging with plugins such as Honey, AdBlock, uBlock, Pi-hole, VPNs, and browsers such as Brave may prevent your order from tracking.
  • You must accept and allow all 3rd party cookies on the retailer's page if requested.
  • You must always return to TopCashback and click the 'get cashback' button through to the retailer's website for each new transaction. Ensure the TopCashback link is the last one used to visit the retailer's website prior to completing your purchase.
  • To be eligible for cashback, all transactions must be completed solely & wholly online and must not be assisted/negotiated via phone/chat/email. Failure to do so will cause tracking to fail and/or have cashback declined.

  • SIM must be activated within 30 days of purchase, and must not be deactivated until your cashback is payable. If the SIM is deactivated prior, Boost may decline cashback.

    The important part. how long before cashback is paid?

      Some of us are using this SIM for a spare number and not porting in our regular number. I pay $6 (after cashback) for this SIM with a new number, do not recharge and let the number expire.

      In the post description:

      Please note that letting the number expire and not recharging is eligible for cashback.

      To answer your question, cashback is usually paid in about 3 months. The last two transactions were paid early. Estimated payable is up to 15 weeks.

      My previous Boost orders:

      • 28th June Purchase. Paid on 12th August.
      • 12th May Purchase. Paid on 24th July.

      In the last few months, Telstra/Boost have "confirmed" early (before 30 days) at TopCashback. Some people have mentioned that they didn't activate (or have ported out) when it turned "confirmed" (before 30 days) and received cashback. It's not a guarantee though.

      What do the statuses 'pending', 'confirmed' and 'payable' mean?

      • cheers. no good for sim slutting, because you potentially need to pay 2 full priced months.

        Ongoing Recharges $39

        so it might cost you $91 (-$7 cb) for the 90 days or $130.(-$7 cb) for 91+ days.

        The real deal is the $330 (-$85 cb)

    Sad days of profit offers are gone :(

  • Activate by 2 March 2026

    SIM must be activated within 30 days of purchase

    Which is it?

    • +1

      Sorry for the confusion. For cashback, SIM must be activated within 30 days of purchase. Please see my reply here regarding this term.

      I've deleted the date (from Boost link) in the post description to avoid confusion. Thanks for pointing out.

    Hmmmm… $6. I dunno.

  • Is it trouble free to port from Boost to Amaysim. How long does that take usually.

  • Anyone else have error issues with the cart/finalising the forms with boost website? Ive tried multiple times and different browsers

      @stevtom27 When you are unable to pay due to "SORRY, SOMETHING WENT WRONG" message or similar, please try the following suggestions:

      • Use a debit card (instead of credit card).
      • Use a different email.
      • Type your address manually.
        (i) Type any address and choose "I can't find my address" as shown here.
        (ii) Add your address manually in the "Address" section shown here. It's below "Delivery address".
        (iii) Vary a little e.g. St instead of Street, Ave instead of Avenue etc.
      • Vary your name e.g. Pete instead of Peter, Bob, Rob instead of Robert etc.

      If you experience any issues at the checkout page, start all over again to ensure tracking. Click the pink button at TopCashback through to Boost website again.

      All the best.
