Am I getting the nbn speed I pay for?
Check three things.
- Read your plan’s published typical evening speed — Aussie Broadband lists 23/9 Mbps on its 25/10 plan and 47/18 Mbps on its 50/20.[1]
- Test over Ethernet, not Wi-Fi, between 7pm and 11pm.
- Compare: matching that published figure means the line performs as sold.
That is the test. The rest of this piece works through the questions that follow it, in the order a frustrated customer asks them: what the plan listing promises, how to run the test so the result means something, whether half speed on a 100 Mbps plan is a fault, whether Australia’s median fixed download of 259.32 Mbps in August 2026 has left your plan behind, what you pay once the six-month promo lapses, whether your address qualifies for a $0 full-fibre upgrade, and where to take a line that underperforms.
What did your provider promise: the tier name or the evening number?
The tier name is a label. The number your provider owes you is the typical evening speed it publishes against that plan, averaged over the 7pm to 11pm window. Aussie Broadband states that window on its own plan listing and publishes separate download and upload figures for every nbn plan it sells.[1]
Read what those figures say. Basic Plus 25/10 is listed at 23 Mbps down and 9 Mbps up. Value 50/20 is listed at 47 Mbps down and 18 Mbps up.[1] Both sit under the headline number on the bill, and both are disclosed before you sign. A 2 Mbps gap on the 25/10 and a 3 Mbps gap on the 50/20 are the product, not a fault.
So a wired evening test landing at 46 Mbps on a 50/20 plan is the product working as sold. A support call about it burns your night and gets you nowhere.
Every retailer publishes its own evening figures against each plan, and they differ. Advertised typical evening downloads across the providers listed on ProductReview.com.au in September 2026 ran from 10 Mbps to 2,000 Mbps.[6] Find yours on the plan page or the critical information summary before you run anything.
Should you run the speed test over Wi-Fi or an Ethernet cable?
Run it over Ethernet first. nbn’s own optimisation material treats wired versus wireless, router quality, connected devices and network congestion as four separate variables, so a Wi-Fi-only result cannot tell you whether the line or your home network is the limit.[3]
The method is short. Plug a laptop directly into the router with a cable. Pause background downloads and streams across the house, console updates included. Test between 7pm and 11pm, the same window Aussie Broadband’s published figure describes.[1] Run it across two or three different nights and write down download, upload and latency each time. Ookla measured 18 ms median latency on Australian fixed broadband in August 2026, which is a useful sanity check on that third number.[5] Then run the same test again on Wi-Fi, from the room you actually stream in and with the usual count of devices still connected — that second result is what separates router placement and channel contention from the line itself, the split nbn draws between “Wired vs wireless” and “Your connected devices”.[3]
The two results do the diagnosis. Wired matching the published evening figure while Wi-Fi lands well under it points at the router, its placement, or the count of devices sharing the channel. Both falling short is a line or a plan question worth chasing.
Is 50 Mbps on an nbn 100 plan a fault or the disclosed speed?
Around half the tier is a fault. The disclosed shortfalls Aussie Broadband publishes on its cheaper plans are small — 23 Mbps against a 25 Mbps headline, 47 Mbps against 50 — and that is the pattern a 100 Mbps plan should follow at 9pm.[1] Aussie Broadband carries the same 7pm–11pm field on the Fast 100/20 card; we have not recorded that figure here, so read it off your own plan page before you judge the result.
That published number is the ruler. A few Mbps under it is the service you bought, on any tier.
Half the tier is a different animal. An iiNet customer posting to ProductReview.com.au in September 2026 reported being billed for a 100 Mbps plan while the connection sat around 50 Mbps, with the fault ticket closed and no follow-up.[6] Several wired evening tests landing near half the tier is a fault, and the last section of this piece tells you where to take it.
Is your connection slow, or is everyone’s slow in Australia right now?
Ookla’s Speedtest Global Index put Australia’s median fixed broadband download at 259.32 Mbps in August 2026, with 51.51 Mbps upload and 18 ms latency.[5] A legacy 50 Mbps plan now sits far below the national middle, so an outdated plan is a likelier cause of slow evenings than a fault.
Ookla recalculates those country medians monthly from user-initiated tests, and that August 2026 read ranked Australia 47th globally for fixed broadband.[5] Worth one more comparison: median mobile download measured 177.44 Mbps at 27 ms latency in the same month, faster than several fixed tiers and with higher latency than the 18 ms fixed median.[5]
Nothing in your house has to break for the connection to feel worse than it did. The plan stayed still. The national middle did not, and neither did the number of devices streaming in your living room.
Is your plan cheaper for the first six months and dearer after?
Very likely, and the delivered speed does not move when the price does. Aussie Broadband’s listing, checked 20 September 2026, shows Basic Plus 25/10 at $58 a month with promo code SPRING25 rising to $83, Value 50/20 at $70 with the same SPRING25 code rising to $95, and Fast 100/20 at $79 with promo code SPRING20 rising to $99.[1] All figures in AUD, from the provider’s own plan page. The cheaper two rates need the code entered; without it you do not get them.
The failure mode is a silent $20 to $25 step-up at month seven. Pull up your current bill and put it next to the plan page before you conclude you are getting bad value per megabit.
You have a lever. Aussie Broadband lists its residential nbn plans as unlimited data with no lock-in contract, so a mismatched tier or a lapsed promo can be changed without an exit fee.[1] Ask for the offer rather than assuming it applies to you: one Aussie Broadband customer reported being refused the $85 six-month new-customer rate while paying $99, and switched providers over it.[6]
Can you get a free upgrade to full fibre at your address?
Possibly, and this is the step before you pay for a higher tier. A speed tier cannot exceed what the access technology at your premises can carry.
nbn runs an address-level check that returns the network status and connection situation for a specific address, and publishes a dedicated path to upgrade homes still on older technology to full fibre.[2] Start with your retailer: Aussie Broadband carries an “nbn $0 FTTP upgrade” as a standing quick link for residential and business customers.[1]
Anyone on an older fixed-line technology who is about to pay $99 a month for a faster plan should run that address check first. You may buy speed the line cannot deliver.
What can you do if your provider closes the fault ticket without fixing the speed?
Raise it with your provider before you go anywhere else. The Telecommunications Industry Ombudsman says skipping that step adds five extra days to a case, and that the provider then has 10 working days to propose a resolution, after which the TIO can investigate if you are not satisfied.[4]
Speed sits squarely inside the TIO’s remit. It lists “Faults” as a category covering a service that isn’t working, has dropped out, or where quality is unacceptable.[4] A plan that never reaches its published evening figure is a quality complaint, not an edge case. The TIO says it helped 51,264 individuals and 6,328 small businesses in the last year.[4]
Bring four things: your dated wired evening results, the published typical evening speed for your plan, the dates you contacted the provider, and the fault ticket reference. The 100 Mbps connection delivering around 50 Mbps with the ticket closed is exactly the case this path exists for.[6]
Where the named plans and checks sit
| Plan (Aussie Broadband, checked 20 Sep 2026) | Published typical evening speed | First 6 months | Ongoing |
|---|---|---|---|
| Basic Plus nbn 25/10 | 23/9 Mbps[1] | $58 with SPRING25[1] | $83[1] |
| Value nbn 50/20 | 47/18 Mbps[1] | $70 with SPRING25[1] | $95[1] |
| Fast nbn 100/20 | 7pm–11pm field on the plan card; figure not recorded in our sources[1] | $79 with SPRING20[1] | $99[1] |
Those evening figures are the benchmark your test result gets measured against. Prices are Aussie Broadband’s own, in AUD, on the date shown, and the promo rates require the code in the cell.
For the line itself, use nbn’s address-level status check and its full-fibre upgrade path.[2] For the national yardstick, use Ookla’s 259.32 Mbps August 2026 median.[5]
For choosing a retailer, owner sentiment splits by brand rather than by speed tier: ProductReview.com.au’s ISP category in September 2026 had brand scores running from 4.9 down to 3.0 among providers selling the same tiers over the same network.[6]
So what should you do tonight?
Plug in the cable, kill the background traffic, and test between 7pm and 11pm. Then put the result next to your plan’s published typical evening speed and pick one of three moves.
If the result matches the published figure and the house still fights over bandwidth, the plan is what needs changing. Move up a tier, and price it on the ongoing rate rather than the six-month promo: $99 rather than $79 on Aussie Broadband’s Fast 100/20.[1] If the result lands far short of the published figure across several wired evening tests, treat it as a fault. Provider first, 10 working days for a proposed resolution, then the TIO.[4] And before you pay anyone for more speed, run nbn’s address check and see whether the $0 full-fibre upgrade covers you.[2]
That is the honest answer to “am I getting the nbn speed I pay for”: compare against the evening number, not the tier name. Aussie Broadband prices, promo codes and evening speeds checked 20 September 2026; Ookla’s medians are its August 2026 read; ProductReview scores as of September 2026. This piece is an editorial synthesis of those provider listings, nbn’s published material, Ookla’s measurements and Australian owner reviews — we have not lab-tested anybody’s line.
