Why get an unlimited data NBN plan?

The main reason you'd consider an unlimited data NBN plan is because it means you never run the risk of bill shock. If you have unlimited data, there's no way you can use more than what you're paying for. You can download and stream to your heart's content!

Is an unlimited data plan expensive?

Since unlimited data is now very much the norm when it comes to fixed-line internet plans, it's hard to call it expensive. There are cheap unlimited data plans and there are pricey unlimited data plans - in fact, the biggest factor that affects the price of your plan is your speed. A slow unlimited NBN plan will be cheaper than a fast unlimited NBN plan. Read more about NBN speeds here .

Is unlimited really unlimited?

For the most part, yes, unlimited data is actually unlimited. If you're signing up for an unlimited data internet plan in Australia, you can download as much as you want, and your telco can't cut you off or slow your speeds. This would be classed as misleading and deceptive conduct, and Australian telcos have gotten in trouble with the ACCC over this in the past.

How much does unlimited NBN cost?

Unlimited NBN prices vary depending on the Internet Service Provider (ISP) but can range from $69 per month all the way up to $150.

How are unlimited NBN plans different?

While unlimited data NBN plans all share a common feature – unlimited data – there are plenty of differences. The biggest is the NBN speed the plan is configured on , but there are a number of other factors to consider.

Are there any downsides to unlimited?

While unlimited NBN plans are cheaper than they've ever been, unlimited data might not be the best option if you're not online much. Some telcos still offer plans with 100GB, 200GB, or 500GB of data for a little less than most comparable unlimited data plans. If you know you'd never use more than 200GB in a month, it might be worth taking up a smaller plane to save yourself a bit of cash.
