In one line: from 1 July 2026, the wholesale price nbn charges internet providers went up slightly, and most retail NBN plans will follow with a small increase — here’s what actually changed and what you can do about it.
What Actually Changed
Each year, nbn co adjusts the wholesale prices it charges phone and internet providers (the companies you actually pay, like Telstra, Optus, or Aussie Broadband). According to nbn’s own announcement, the increase from 1 July 2026 was tied to CPI (inflation) over the year to December 2025, and varies by speed tier:
- Basic (12/1 Mbps) plans actually went down slightly, by about 1 cent a month.
- 25 Mbps tier plans rose by roughly $1.08 a month at the wholesale level.
- 50 Mbps and “up to 100 Mbps” fixed wireless tiers rose by about $2.34 a month.
- 500 Mbps and 1000 Mbps tiers rose by roughly $1.95 to $2.32 a month.
Those are wholesale figures — what nbn charges your provider, not what you pay directly. Retail providers set their own prices, and some have flagged retail increases in a similar range for popular plans, though this varies by provider and plan. It’s worth checking your own bill or provider notice rather than assuming a figure applies to you.
If This Is Your Home Internet
- Check your next bill or your provider’s email for a specific price change notice — providers are required to tell you before a price rise takes effect.
- If your plan is going up, it’s a reasonable moment to compare plans. With more than 150 registered nbn providers, switching is often easier than people expect and doesn’t usually require any new equipment.
- If you’ve been on the same speed tier for a couple of years, check whether a lower tier now meets your actual usage, especially if it’s mainly browsing, email and streaming for one or two people.
If This Is Your Business Internet
- Business nbn plans are adjusted in line with CPI too, so expect a similar small increase if you’re on a standard wholesale-based plan.
- If your business relies on stable, always-on internet — EFTPOS, cloud accounting, VoIP phones — this is a good trigger to review whether your current plan’s speed and reliability still match what the business actually needs, not just the cheapest option available.
- Ask your provider about business-grade options with service level agreements if you haven’t compared them before; residential-grade plans don’t always come with the same fault priority.
A Note for Regional Eyre Peninsula Connections
Plenty of properties around Port Lincoln and the wider Eyre Peninsula run on nbn Fixed Wireless or Sky Muster satellite rather than a fixed-line connection, particularly outside town. Fixed Wireless sits in the “up to 100 Mbps” tier affected by this year’s increase, so it’s worth checking your plan type before assuming the fixed-line figures above apply to you. If you’re unsure which technology your address actually uses, nbn’s connection information is the place to check, since it affects both your pricing tier and your realistic speed expectations.
Slow Internet Isn’t Always About Price
If your connection feels sluggish, a price rise isn’t necessarily the cause — router placement, wifi congestion, or an ageing modem can matter just as much as your plan’s speed tier. We’ve covered common causes and fixes in our guide to common Wi-Fi problems at home.
