The best prepaid plans in Australia should offer low prices and generous data inclusions, with an eye towards flexibility above all else. Most telcos would rather you select one of the best postpaid plans if they offer them, but in the prepaid world, your plan is handled through recharges rather than rolling costs after the month of service, giving you the edge if you want to change providers regularly and don't want to fork money over until you're ready to do so.

Long term data periods across several months or plan lengths as low as seven days are also an option with a prepaid plan, but a casual user will likely gravitate toward monthly or 28-day billing cycles.

Looking at the best SIM-only plans in Australia broadly, you might want to pick up a prepaid plan if you want to pay up-front for your data. That’s the point of this article; we’ve found the best plans for various lifestyles, allowing you to control your spending within a period that suits you. Just ensure that you’re getting the right amount of data every month, otherwise you may rack up bills for going over your monthly limit.

Let’s dive into the best prepaid plans in Australia – from budget oriented options to year-long big data selections.

Best prepaid mobile plans: our picks

Best prepaid plan for most people

TPG | 25GB data | 1-month expiry | AU$12.50 per 28-day renewal (first six renewals, then AU$25 per renewal)

This TPG prepaid plan is 50% off for your first six renewals, so you’ll initially pay just AU$12.50 for 25GB of data. After that discount ends, you’ll be paying AU$25 for each 28-day renewal. TPG’s prepaid plans auto-renew every month until you cancel. TPG’s prepaid plans use Vodafone’s 4G network.

Total minimum cost is AU$12.50 | Total cost for first year: AU$225 | Yearly cost after discount: AU$300

Best cheap prepaid plan under AU$20

TPG | 50GB data | AU$17.50 per 28-day renewal (first six renewals, then AU$35 per renewal)

Déjà vu? While the best prepaid plan for most people is TPG’s 25GB option, the 50GB option isn’t much more expensive, with a discount running for the first six renewals that brings the price down to AU$17.50 per 28-day renewal (AU$35 after). This plan includes access to the Vodafone 5G network, unlimited international minutes for calls to 31 countries, and 50GB of data every month (speed-capped at 150Mbps). If you crave a big data allowance, this plan might be your best bet.

Total minimum cost is AU$12.50 | Total cost for first year: AU$315 | Yearly cost after discount: AU$420

Best unlimited data prepaid plan

Felix Mobile | Unlimited data | 28-day expiry | AU$20 for first three 28-day renewals (then AU$40 per renewal)

Felix Mobile is one of the few telcos in the country to provide unlimited data on a phone plan – and if you’re a data craving phone user who doesn’t care about download speed, this plan could be made for you. Pay only AU$20 per renewal for the first three renewals to access unlimited data with a 20Mbps speedcap (which is quite a lot slower than the speed caps applied to the other plans on this list, and isn’t suitable for things like 4K streaming and quick downloads of big files). Felix Mobile’s plans use the Vodafone network.

Total minimum cost is AU$20 | Total cost for first year: AU$420 | Yearly cost after discount: AU$480

Best long expiry prepaid plan up to 365 days

Best Telstra network prepaid plan

Belong | 25GB | 1-month expiry | AU$30 per renewal

Belong takes the best Telstra network prepaid plan spot for two reasons – the data-to-price ratio is quite reasonable and it’s one of the cheapest MVNO prepaid plans to have 5G access on the Telstra network. That’s partially because Belong is 100% owned by Telstra as its budget telco option. Belong customers also get access to data rollover and data gifting to other Belong users.

Total minimum cost is AU$30 | Total cost for first year: AU$360
