The best prepaid plans in Australia offer flexibility, cost savings, and no contracts, ranging from the cheapest deals to extensive data and year-long options. While telcos prefer postpaid plans, as they guarantee a certain period of income, prepaid plans allow for much further personalisation; letting you jump from service to service as you please to take advantage of the best deal.

That personalisation comes in many forms, like monthly data, 4G or 5G connectivity and international calls and texts, but the main advantage is the ability to choose different plan lengths. While most people go for 28-day or monthly billing, plans can range from as short as seven days to 365 days. Like the best SIM-only plans, they allow you to pay for what you need better than the best Vodafone or Optus plans, whose most affordable plan offers 50GB of data.

These are Australia's top prepaid plans, offering flexibility, cost savings, and no lock-in contracts, from budget-friendly choices to year-long big data selections. Let’s dive into the best prepaid plans in Australia – from budget oriented options to year-long big data selections.

Best prepaid plan for most people – TPG 50GB data for AU$17.50
Best cheap prepaid plan under AU$20 – TPG 25GB data for AU$12.50
Best unlimited data prepaid plan – Felix Mobile unlimited data for AU$20
Best long expiry prepaid plan up to 365 days – Kogan Mobile 500GB for AU$199
Best Telstra network prepaid plan – Superloop 15GB for AU$25
Best Optus network prepaid plan – Yomojo 25GB for AU$12.45
Best Vodafone network prepaid plan – TPG 50GB data for AU$17.50

Best prepaid mobile plans: our picks

Best prepaid plan for most people

TPG | 50GB data | AU$17.50 per 28-day renewal

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

Thanks to a variety of deals available from each provider, there's a ton of options around this AU$15 to AU$20 per month price tag. Specifically, the Yomojo 'Unlimited Voice & SMS + 40GB' plan is a key competitor. However, the reason TPG wins-out at this price is due to its 5G connectivity on the Vodafone network. This plan offers a 50% discount on the first six renewals. It includes 50GB of data each month (speed-capped at 150Mbps) and unlimited international calls to 31 countries.

Total minimum cost is AU$17.50 | Total cost for first year: AU$315 | Yearly cost after discount: AU$420

Best cheap prepaid plan under AU$20

TPG | 25GB data | AU$12.50 per 28-day renewal

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

This TPG plan, a smaller version of the one above, offers significant value at just AU$12.50 per month, thanks to a 50% discount for the first six months. You get 25GB of monthly data and 100 minutes for international calls. It's cheaper because it only offers 4G connectivity, unlike the plan above. However, for users who don't require maximum internet speeds, the lower cost is likely a stronger appeal. Again, Yomojo's offering is highly competitive, with the Unlimited Voice & SMS + 25GB SIM for just AU$12.45.

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

Best unlimited data prepaid plan

Felix Mobile | Unlimited data | 28-day expiry | AU$20 for first three months

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

Felix Mobile is one of the few telcos in Australia to offer an unlimited data phone plan. If you're a data fiend who isn't bothered about download speed, this plan could be perfect for you. Pay only AU$20 per renewal for the first three renewals for unlimited data with a 20Mbps speed cap. Note that this speed cap is much slower than those on other plans listed and isn't ideal for things like 4K streaming or quick downloads of large files. Felix Mobile 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

Kogan Mobile | 500GB | 360-day expiry | AU$199

Kogan Mobile | 500GB | 360-day expiry | AU$199 (then AU$300)

Kogan Mobile takes the top spot for long expiry with its Large plan, even outdoing another Kogan plan that offered 300GB for AU$179. This plan lets you earn Qantas points, operates on the Vodafone 4G network, and gives you Kogan's AU$300 plan for just AU$199, along with a massive 500GB of data.

Total minimum cost is AU$199 | Total cost for first year: AU$199 | Total cost without discount: AU$300

Best Telstra network prepaid plan

Superloop | 15GB | 1-month expiry | AU$25 per 30-day renewal

Superloop | 15GB | 1-month expiry | AU$25 per 30-day renewal

Whatever you're after on the Telstra network, Superloop's SuperSim plans are your best bet. This is Superloop's cheapest offering, providing 15GB of data for AU$25 per month. It offers 4G connectivity to the Telstra network, which is the largest in Australia. Importantly, it also offers unlimited International calls & SMS to 15 countries. The more expensive 25GB Superloop adds 5G connectivity for AU$35 p/m.

Total minimum cost is AU$25 | Total cost for first year: AU$300

Best Optus network prepaid plan

Yomojo | 25GB data | AU$12.45 per 30-day renewal

Yomojo | 25GB data | AU$12.45 per 30-day renewal (for the first six months when you port your number, then AU$24.90 p/m)

While it just missed out on being our pick for the best cheap plan (and the best plan overall with its pricier option), we think the Yomojo 25GB plan is the best option if you want to connect to the Optus network.

Total minimum cost is AU$12.45 | Total cost for first year: AU$224.10 | Total cost without discount: AU$298.80

Best Vodafone network prepaid plan

TPG | 50GB data | 1-month expiry | AU$17.50 per 28-day renewal

TPG | 50GB data | 1-month expiry | AU$17.50 per 28-day renewal (first six renewals, then AU$35 per renewal)

This TPG offering is considered the best prepaid plan overall, and since TPG connects to the Vodafone network, it should be no surprise it's the top choice here . TPG is offering 50GB of data for AU$17.50 for the first six renewals. After that period, the cost increases to AU$35 per renewal. Your prepaid plan will automatically renew every 28 days. iiNet is also a great option, with an identical offering to TPG.

Total minimum cost is AU$17.50 | Total cost for first year: AU$315 | Yearly cost after discount: AU$420
