What Can You Complain About?

Under Australian Consumer Law and the Telecommunications Consumer Protections (TCP) Code, you have certain rights as a telco customer. This includes the right to:

How to complain to your internet provider
  • Receive an internet service that works properly and is of acceptable quality.
  • Get the features, speed and reliability that were advertised.
  • Be billed clearly and accurately.
  • Access hardship assistance if you're unable to pay.

If you're not getting what you paid for — whether that's speed, service, or support — you're well within your rights to raise a complaint.

How to Prepare a Complaint to Your Internet Provider

Before reaching out to your provider, make sure you're prepared. Most telcos offer multiple support channels, including phone, online chat, email, web forms, or even mail. Phone and chat are often the fastest ways to speak with someone, but they can come with long wait times and may not give you time to think through what you want to say.

To improve your chances of success:

  • Have your customer details handy — including your account number.
  • Collect evidence — such as screenshots, speed tests, or previous bills.
  • Know what you want — write down a proposed solution or outcome that would satisfy you.

💡 Tip: If you're living with a disability, experiencing financial hardship, or need support in another language, your provider must offer appropriate assistance.

Make Sure You're Speaking to the Right Team

Not all departments can handle all complaints. Telcos like Telstra, Optus or TPG usually have separate contact numbers for billing, technical issues, and sales — and choosing the right one can save you time and frustration.

If the representative you speak to doesn't have the authority to help, politely ask to be escalated to a senior staff member.

Be Polite But Persistent

It's easy to get flustered when your internet keeps dropping out or your bill has spiked unexpectedly. But staying calm and respectful — while being assertive — will go a long way.

  • Keep your tone professional, even if you're frustrated.
  • Avoid yelling or using aggressive language — it's rarely productive.
  • If you're not comfortable talking, consider emailing or using live chat. This gives you more time to gather your thoughts and provides a written record.

What if my complaint isn't resolved?

If your provider fails to resolve your complaint within the specified timeframes, or if you're not satisfied with the resolution, you can escalate the matter to the Telecommunications Industry Ombudsman (TIO). The TIO is an independent dispute resolution service that can help mediate between you and your provider.

When to Contact the Telecommunications Industry Ombudsman

If you've gone through your provider's complaints process and your issue still isn't fixed, the next step is to contact the TIO. You can lodge your complaint:

  • Online via the TIO website
  • By phone
  • And track your case or submit updates throughout the process

The TIO investigates complaints that remain unresolved or where the telco has failed to respond in time. Even relatively small issues may be accepted if your provider hasn't met its obligations.

Are Complaints Justified?

Australia's internet isn't known for being world-class — and if you're paying for a premium NBN plan but getting below-par speeds or terrible service, it's understandable to feel let down.

Being clear about your expectations and calm when presenting your issue can often lead to a resolution. But if your provider can't (or won't) fix things, the TIO is there to help — and switching providers may be your best option.

Should I Switch Providers?

If your internet provider isn't delivering the service you're paying for — whether that's speed, reliability, or customer support — then switching could be the smartest solution. Constant dropouts, unresolved complaints, or poor communication are all valid reasons to consider a change.

Before you make the move, compare other providers and check what kind of speeds and support they offer in your area. Many NBN providers now offer contract-free plans with discounted introductory rates, so you can try a new service without long-term commitment.

In short: if your current provider isn't listening, it might be time to find one that will.
