Here are the best cheap mobile phone plans in Australia (June 2023)

If you are in the market for a cheap mobile phone plan, there are plenty of low-cost options.

Whatever your needs,  you can score a decent plan for under $20 with ample monthly data. And you only need to make a small increase to your budget to if you want more gigabytes and shiny perks.

In this guide, we're looking at the best-value SIM-only plans (Prepaid and Postpaid), kicking off with those under $10 and stretching up to a max cost of $40, including cheap unlimited plans and plans on all three networks.

At this price point, plans often only come with a few gigs of data, so the fact that you get 12GB with this plan from TPG makes it great value.

Note that this pricing only lasts for the six months, after which you'll pay $20 per month. The plan is contract-free, so you can always swap provider before you fee goes up. 

TPG's mobile plans are powered by the Vodafone 4G network. 

Not quite what you’re after? Here are the most popular mobile plans for $10 and under today.

This price bracket is a tricky one, as most of the popular picks are technically only $20 or under for a promo period - typically six months. Still, TPG's deal on its 45GB Monthly Plan nets you a huge amount of monthly data for $15 per month

Once the promo runs out, however, things get a little dicey. After six months the price will revert back to $30 a month. All things considered, that's still a pretty decent deal. If you're an existing TPG internet customer, you'll pay a slightly cheaper rate of $25 per month after your initial discount runs out.

The plan runs on the Vodafone 4G network and includes all the usual unlimited call and text trimmings. 

If you want to check out your options, here are some more popular mobile plans at this price point.

Dodo currently has a great offer for anyone looking for a lot of data without breaking the bank. $30 per month gets you a 80GB data allowance including 40GB bonus for 3 months, plus unlimited standard calls and texts.

Dodo is powered by the Optus 4G network. You won't have 5G speeds but you should have coverage in most populated parts of Australia.

If a hundred gigs still won't suffice, there is one more option. While there are no truly 'unlimited' data plans in Australia, there are a decent handful that offer 'endless' or 'infinite' data, which means you can use as much data as you please, but it will be speed-capped.

The best option for most people is felix mobile's $35 subscription plan, which offers 'endless' data that's capped at 20Mbps. At that speed, you can do most things comfortably, from streaming HD video, updating apps, online shopping, scrolling through social media and video chatting with friends and family. Really, the only thing you'll struggle with is downloading large files, which may take a while.

If you want to try before you buy, you can currently get 50% off on your first three months. This offer runs until the end of May.

If you're looking for a cheap prepaid plan that also includes international calls, amaysim is a solid choice. You'll get 35GB for $29.90 on a 30-day expiry. 

The plan also unlimited international calls and texts to 35 select countries, a further 300 minutes for Zone 1 destinations, and an extra 30 minutes for Zone 2. You'll be able to call almost anywhere with this plan.

If you're looking for one of the cheapest plans on the Telstra mobile network, you need to look no further than the Numobile $15 SIM plan. Priced at $15 per month, this plan is a few bucks more expensive than PennyTel's Extra Small plan but includes more than double the data.

If you have specific requirements that don't match up with what Numobile are offering here, there are plenty of other MVNOs on the Telstra wholesale network that will connect you to the largest mobile network in Australia for a fraction of the cost. Here's an updated list of the cheapest mobile plans on the Telstra network.

The cheapest way to jump onto the Optus network on short notice remains the carrier's own $1 per day prepaid SIMs. However, if you're looking for coverage measured in weeks or months rather than days, you're better off going with something like Moose Mobile's $8.80 mobile plan.

$8.80 per month gets you 6GB of data for the first twelve months plus unlimited national calls and texts. After that year, the monthly rises to $14.80 per month. Fortunately, it's a no-contract plan, so you're free to shop around when that higher price eventually kicks in and save money in the meantime.

If Optus works best in your area, and you're not interested in switching to Moose, Telstra or Vodafone, there's a bunch of smaller providers that offer access to the Optus 4G network for lower monthly price (though Optus plans can be quite cheap).

For those looking to stay with or seek out the coverage of the Vodafone's 3G and 4G networks while saving as much money as possible, iiNet's 8GB Mobile Plan is a clear frontrunner.

Priced at $10 per month for the first six months, this plan includes 8GB of mobile data. After that honeymoon period, the price does go up to $19.99 per month. However, at that point, you are free to leave and jump ship to another cheap mobile plan.

Vodafone has a healthy mix of budget prepaid providers that use its network. If you're in a place with ample Vodafone coverage, and you're only interested in cutting back your monthly bills, check out the most popular plans on Vodafone's network.

If you're looking for a cheap data SIM to stick in an iPad, Android tablet, or portable hotspot, our current top pick comes from Telstra's budget brand Belong. You'll pay just $15 per month for a 20GB SIM, which is hard to beat. This plan even has 5G! 

The only catch is that your speeds are limited to 100Mbps. 

Here are a few other cheap data-only plans:

In our top picks above, we've tried to highlight the cheapest plans that offer reasonable data and call inclusions. However, if you're simply after the cheapest prepaid and postpaid plans and recharges Australian telcos provide, take a look at the list below for some truly dirt-cheap mobile plans. This list comes from the database of providers tracked by our sister website WhistleOut. 

If you're looking to cut down on monthly expenses, your phone bill can be a great place to start. Australia's mobile plan market extends far beyond the three big carriers - Telstra, Optus and Vodafone - and so long as you aren't locked into device repayments with another provider the process of switching between to a cheaper mobile plan is relatively painless.

Before you do pull the trigger on a new mobile provider, it's worth doing your research and considering a few key factors.

As a rule, it's usually better and cheaper to have too much data than not enough. Knowledge is power when it comes to choosing the right mobile plan, so it may be worth using an app like My Data Manager to start tracking how much of your monthly data you use. Once you have a better idea of how much data you actually need, finding a plan that offers that amount at the lowest possible price becomes significantly easier.

While there's often overlap between Australia's big three carriers when it comes to coverage, that's little consolation to those who fall through the cracks. If you know that your local area has bad Optus coverage, that's a good reason to exclude cheap mobile plans from providers that rely on the same infrastructure. After all, the savings benefits of a good deal tend to erode pretty fast if you can't get a good signal.

The quality of a mobile provider's customer support isn't usually something that you think about until it's too late. For that reason, those looking at choosing between our picks for the best cheap mobile plans may want to use that variable as a point of difference between potential options. If two plans offer the same amount of data and coverage for a similar or identical monthly cost, a good (or bad) customer service reputation might be a good way to break the tie between them.

At any given moment, there usually dozens of great deals on mobile plans available to Australians. What's more, most of these tend to be contract-free. If you're willing to be diligent and check in to see which providers are running the best deals every few months, there's nothing stopping you from jumping between them to get the most out of your money.

Cheaper mobile plans tend to be light on extras. You don't get value adds like discounted movie tickets or access to streaming services.

In most cases, you're literally paying for talk, text, and data. It also goes without saying, cheaper plans tend to have a smaller data allowance than more expensive plans, but this isn't really an issue if you right-size to your needs. 

Most cheap mobile plans currently don't have 5G access. 

When it comes to cheap mobile plans, price is the most important variable. If you're a budget-conscious consumer looking at this page for guidance, we want our recommendations to best meet your needs. For that reason, we consider cheap plans to be anything less than $40/month.

Beyond price, the other big factors we consider are network coverage and monthly data per dollar. Given the overlap between Australia's major mobile networks, we typically privilege the latter when it comes to picking out the best cheap mobile plans. If you live in an area where you've got decent coverage from Optus, Vodafone and Telstra, we want to be able to point you towards the cheap mobile plan that offers the best bang for buck.

Finally, we also consider whether or not any decent deals are available for a given mobile plan and whether or not that provider includes any notable extras (like international calls) or suffers from any shortcomings.
