ACT Fibernet Offers Free Speed Upgrades Up to 500Mbps: Eligibility and How to Claim

ACT Fibernet has announced a free Diwali speed upgrade for eligible subscribers, boosting existing broadband plans to 100Mbps, 300Mbps or 500Mbps at no extra cost through its app.

ACT Fibernet has announced a free broadband speed upgrade for eligible customers as part of its Diwali offer. The promotion started on November 6, 2026, and gives subscribers access to higher speed tiers based on their existing plan, with upgrades going up to 500Mbps.

Eligible users can access the offer through a banner in the ACT Fibernet app. The company has announced three upgrade brackets, although accounts with outstanding payments, inactive plans and other eligibility restrictions are excluded. Here is how the offer works.

ACT Fibernet Free Speed Upgrade: Eligible Plans

The speed boost depends on the subscriber's current broadband speed. ACT has specified the following upgrades at no additional cost:

Existing Plan Speed Speed Under the Offer
Below 100Mbps 100Mbps
100Mbps to 299Mbps 300Mbps
300Mbps to 499Mbps 500Mbps

For example, a customer on a 100Mbps plan falls in the second bracket and can get a boost to 300Mbps, subject to eligibility. A 300Mbps subscriber falls in the third bracket. ACT has not announced an additional upgrade for plans already offering 500Mbps or more in this release.

The company says the offer is available across its customer base, subject to account eligibility. Subscribers with payment backlogs or currently inactive plans are excluded, along with other ineligible accounts as applicable.

How to Activate the ACT Fibernet Speed Boost

Customers can claim the upgrade through the ACT Fibernet app:

  1. Open the ACT Fibernet app for your broadband account.
  2. Look for the speed boost offer banner.
  3. Tap the banner and follow the instructions shown for your account.

ACT's release does not specify an end date for the offer or how long the upgraded speed will remain active after activation. Customers should check the terms displayed in the app before claiming it, particularly the benefit's validity.

What the Upgrade Offers Customers

Higher broadband speeds can provide more capacity when several people share a connection for streaming, downloads and video calls. ACT says the initiative is intended to support increased internet use during the festive season, without customers paying extra for the announced speed boost.

Actual speeds on individual devices can still depend on Wi-Fi coverage, the router and the devices being used. For eligible subscribers, the useful next step is to check the app banner for the exact upgrade and validity attached to their account.
