Most Satisfied Customers | iiNet

iiNet is Canstar Blue’s best-rated business broadband provider for 2021, leading the way in overall satisfaction, value for money, network performance, customer service, bill clarity, and contract clarity & flexibility.

iiNet is Australia’s best-rated business NBN provider

No matter the industry, every small business needs an internet connection to survive. Whether it’s organising rosters, doing the pay run, emailing staff, operating point-of-sale systems, or ordering products, businesses in Australia can thrive with a solid broadband connection. As they say, a small business is only as good as its communications, and having reliable and fast internet is a sure-fire way to keep communications flowing. So if your small business is less than satisfied with your current internet provider, our 2021 review and ratings may help you find a better deal.

Canstar Blue annually surveys hundreds of business owners and key decision-makers across Australia to find out which broadband providers are consistently delivering, and which are more like a bump in the road. Returning to the number-one spot for the seventh time, and recovering from its 2020 loss to Optus, is frequent favourite iiNet. 

The telco smashed our 2021 ratings, receiving five stars across all categories including overall customer satisfaction. iiNet’s competitive business NBN prices – and range of plan options – have seen the provider continue to dominate our yearly ratings, ahead of industry leaders Telstra, TPG and Optus. 

While no NBN provider is perfect – and it seems reasonable to assume you’ll have the occasional issue with any telco – our ratings are designed as a high-level guide to which providers are getting it right more often than not, and which ones still have work to do.

Business NBN Plans

There is a diverse range of internet plans on offer for businesses big and small. Here is an overview of what the biggest internet providers in Australia are offering business owners when it comes to NBN.

iiNet Business NBN Plans


iiNet’s small business broadband options include both NBN, VDSL2, fibre and cable connections, with unlimited data and high-speed NBN plans available. Unlimited data plans begin at $79.99 per month for business NBN customers, and include pay-as-you-go calling, a static IP address, and a free Wi-Fi modem on 24-month contracts.

  • The first NBN speed offered is the Standard Plus Evening Speed (NBN 50) speed tier, but a boost to Premium NBN 100 is available for an extra $30 per month.
  • Customers can add a BizPhone pack to their plan from $29.95 per month, which includes unlimited standard local, national and mobile calls.
  • Plans are available on monthly or 24-month contracts, but going contract-free will incur a $79.95 activation fee, plus an $89 modem charge if required.

iiNet blitzed our business broadband ratings for 2021, taking home a perfect five-star result for not only overall satisfaction, but also network performance, value for money, customer service, bill clarity, and flexibility of contract.

TPG offers small business NBN plans from $69.99 per month at Basic NBN 12 speeds. NBN 50 and NBN 100 options are also available, and all include unlimited data and your choice of a month-to-month or 18-month contract.

  • No lock-in contracts incur a $99.95 setup fee, but both contract options come with an included WiFi modem.
  • Selected areas may also have access to TPG’s high-speed fibre optic broadband plans, which start at $399 monthly for speeds up to 400Mbps and $799 for 1Gbps.

Optus’ small-to-medium business broadband is priced on par with its residential NBN and ADSL plans, with prices beginning from $79 per month for unlimited data. NBN plans include Standard Plus (NBN 50) speeds as standard, with a boost to Premium NBN 100/20 available for an additional $20 per month.

  • Internet Ultimate plans include an Optus WiFi Booster and Optus WiFi Secure protection.

Optus scored three stars for overall satisfaction in 2021, and received four stars for value for money, customer service, and flexibility and clarity of contract.

Telstra Business NBN Plans

Telstra Business Internet Plans

Small business broadband from Telstra begins at $100 per month for unlimited data for both NBN and ADSL customers. Plans are available on a casual month-to-month basis, and new customers will receive a Telstra Smart Business Modem with 4G mobile broadband backup. However, cancelling your service within 24 months means you’ll need to pay out the remaining cost of your modem. 

  • NBN customers receive Standard Plus (NBN 50) speeds as standard, but can add a Premium (NBN 100) speed boost where available.
  • Business broadband and calling pack bundles begin at $125 per month and include unlimited data at NBN 50 speeds, plus phone line and unlimited standard local, national and mobile calls, plus unlimited calls to selected countries.

Telstra was rated three stars for overall satisfaction in our 2021 review, and received five stars for flexibility of contract and four stars each for network performance and bill clarity.

What did we learn about business NBN customers?

  • 29% regularly suffer from slow or unreliable internet.
  • 39% have had an internet outage affect their business.
  • The average monthly broadband cost to businesses is $210.

Choosing an NBN plan for your business

No business should have to put up with a subpar NBN plan. Often, the internet is the lifeblood of a business, and having a lacklustre plan can be both frustrating and financially impairing. This year, two providers in our annual review were rated five stars in terms of network performance – iiNet and TPG.

If value for money is a key factor in finding a NBN plan, liiNet and TPG each scored five stars for value in our 2021 ratings, followed by Optus with four stars and Telstra with three. In terms of customer service, only iiNet was rated five stars, and iiNet and TPG each received five stars for bill clarity. 

What’s most important to business owners will vary, but our ratings provide a guide as to which telcos are keeping customers happy across various categories.

Frequently Asked Questions

Canstar Blue surveyed 2,107 Australian small to medium-sized business owners or key decision-makers (i.e. the key decision-maker for the business) across a range of categories to measure and track customer satisfaction, via ISO 26362 accredited research panels managed by Qualtrics. The outcomes reported are the results from customers within the survey group who currently have a business broadband plan and the business pays the bills – in this case, 553 people.

Brands must have received at least 30 responses to be included. Results are comparative and it should be noted that brands receiving three stars have still achieved a satisfaction measure of at least six out of 10. Not all brands available in the market have been compared in this survey. The ratings table is first sorted by star ratings and then by mean overall satisfaction. A rated brand may receive a ‘N/A’ (Not Applicable) rating if it does not receive the minimum number of responses for that criteria.

Here are past winners of Canstar Blue’s Most Satisfied Customers – Business NBN Providers ratings:

  • 2020: Optus
