Unlimited Internet plans have become increasingly popular as families and heavy users seek to stay connected without worrying about data caps or overage charges. Whether you're streaming HD videos, gaming online, or working from home, having unlimited data is a huge advantage.

Affordable broadband is also important for older Australians. Many seniors and pensioners rely on the Internet to stay connected with family, attend telehealth appointments, access online banking, and use essential government services. If you're looking for options designed specifically for older Australians, you can explore our dedicated guide to seniors internet plans to find affordable broadband options, discounts, and plans suited to lighter Internet usage.

In this article, we’ll explore the benefits of unlimited Internet, compare the cheapest options available, and guide you on how to find the best deal based on your usage needs.

Why unlimited Internet plans are ideal for families and heavy users

For households with multiple devices or heavy Internet users, an unlimited Internet plan is often the best choice. With the rise in video streaming, online study, and remote work, traditional capped data plans may no longer be sufficient. 

Unlimited plans allow users to browse, stream, and download without worrying about running out of data or paying extra fees for overages. This peace of mind makes unlimited Internet plans particularly appealing to families, students, or anyone with high data usage. Plus, with the advent of affordable unlimited options, these plans are more accessible than ever.

What are the cheapest NBN plans?

If you want a cheap Internet plan, you might think you have to choose a lower speed. Most providers do, however, offer excellent prices for NBN 50 - which is what makes it the most popular plan. 

There are great NBN deals that find a good balance between speed and data. Let's check out some of the cheapest unlimited NBN plans we have.

Finding the most affordable unlimited Internet plans requires a balance between cost, speed, and coverage. Here are some of the cheapest providers in Australia offering unlimited plans:

NBN 100 plans are not generally considered to be on the cheap side, but when you think about the value you get from it, it’s often worth the upgrade. Most NBN 100 providers have deals and sign up offers that allow you money off when you get connected.

You can stream high definition movies, game for longer and regularly download large files. Most providers offer no lock-in contracts and unlimited data.

Factors to consider: Speed, data limits, reliability

While price is an important factor, there are several other considerations to make when choosing an unlimited Internet plan:

Speed 

The speed of your Internet plan is crucial, particularly for activities like streaming, online gaming, or video conferencing. Different NBN plans offer varying speeds:

  • NBN 50: Ideal for small households with light to moderate usage.
  • NBN 100: Suitable for larger households or those who require faster speeds for HD streaming and gaming.

Data limits 

One of the key benefits of unlimited Internet plans is the lack of data limits, but it's important to ensure that your plan offers sufficient speed and reliability. While many providers offer unlimited data, some may throttle speeds after a certain amount of usage, especially during peak hours.

Be sure to check the fine print to ensure that your provider’s "unlimited" plan doesn't come with hidden restrictions.

Reliability 

Reliability is another crucial factor to consider. Some providers may offer cheaper plans but may not have the best network reliability in your area. Check reviews and coverage maps to ensure that the provider you choose offers stable and consistent service in your location.

Opting for a provider with good customer support and minimal downtime is important to avoid disruptions to your daily Internet use.

How to find the best deal based on usage needs

Finding the best unlimited Internet plan depends on your household's specific usage patterns. Consider the following factors to help guide your decision:

  • Household size and usage: If you have multiple people using the Internet for activities like HD streaming, video calls, and online gaming, opt for a higher-speed plan (e.g., NBN 100) to ensure smooth performance.
  • Budget: Look for the most affordable plan that meets your needs. If you only need moderate speeds, a cheaper NBN 50 plan may suffice, saving you money while providing ample speed for everyday tasks.
  • Customer service and reliability: Research customer reviews to find a provider known for reliable service and good customer support. It’s better to pay a little more for a plan with dependable service than save a few dollars and deal with constant interruptions.
  • Extras: Some plans offer added value, such as access to streaming services, unlimited calls, or better customer support. Consider whether these extras are worth the extra cost based on your lifestyle and needs.

Before taking the leap to switch, it's wise to have a specific Internet service provider (ISP) in mind, having compared the available services. Enquire about no-contract options and, if possible, minimal or no sign-up fees with your potential new provider. 

It's crucial to ensure that the switch doesn't entangle you in a new set of restrictions or clauses that might hinder future changes.

While opting for a more well-known ISP may seem like the popular choice, prioritising savings could lead you to consider a smaller provider. Despite the size, smaller providers can often deliver the quality of service and reliability you seek from your broadband contractor.

Finding the time to understand what your next provider offers, versus the current one that you have - including the good and the bad sides of the service, is essential before finally deciding to make that switch.

Several Internet plans only have a few bucks difference on the same speed tier. Take your time in reviewing terms and conditions, as it could be worth paying an extra couple of dollars if that would provide you with the right speed and more flexibility in your plan.
