How we chose the top 365-day prepaid plans and long expiry mobile plans
The widget above offers a snapshot of prepaid mobile plans that have 365-day expiry. These plans come with unlimited calls and texts and at least 2GB of data, sorted by popularity. These results are pulled from our database of over 30 mobile providers.
Cheapest 365-day prepaid plans
If you're in the market for a 365-day long-expiry plan that offers ongoing value, you will want to keep an eye out for introductory offers. There are some great deals out there that will only last you your first year, after which you will pay significantly more. But if you're not interested in switching plans every 365 days just to find a cheaper deal, you can weed out the limited-time deals by looking at the cheapest plans over 24 months. The plans below offer a mix of ongoing pricing and limited-time deals that ultimately cost you less in the long run.
High usage 365-day plans
One of the downsides to your typical 365-day plan is the possibility of burning through a year's worth of data over a few months. Most people who opt for long-expiry plans do so because they don't need the bountiful data of a regular SIM plan. But as our smartphones evolve, our data consumption grows. Things like background updates and three-hour YouTube documentaries can take their toll and leave you disconnected unexpectedly, so it's never a bad idea to have a little more data than you need.
The plans below still offer 365-day long expiry, but they also offer a lot more data than the cheapest deals on the market. For example, a 500GB plan would be equivalent to 40GB per month. That's more mobile data than most Australians use on average but also enough to allow for peace-of-mind if you regularly commute or don't have a need for home WiFi.
Long-expiry prepaid plans on the Telstra network
If being on the Telstra network is important to you, you don't have a lot of options. However, Telstra's prepaid-only sub-brand Boost Mobile does off some decent deals that come with a 12-month renewal. Telstra itself will only offer as much as 6 months when it comes to long expiry, but Woolworths Everyday Mobile is a decent 365-day alternative that offers value somewhere in between Telstra and Boost.
What are 365-day prepaid plans?
365-day prepaid plans (also known as long expiry plans) are a type of SIM-only mobile plan that lets you lock in a year of on-the-go coverage and connectivity in advance. You pay upfront, but once you've done that, you're free to use all the data and other inclusions your 365-day SIM plan inclusions however you want.
Many people prefer a 365-day plan as it's a single payment per year with no excess data fees or bill shock.
The only catch is that if you use up your data faster than you expect, you may need to recharge and top it up early. Otherwise, you've got an entire year from the moment you sign up for a brand new 365-day mobile plan to use it or lose it.
How to pick the best 365-day prepaid plans for your needs
Long expiry prepaid plans are, by their very nature, relatively straightforward and no-fuss. That simplicity is a big reason that people opt for them. Still, there are a few things to keep an eye out for when choosing a 365-day prepaid phone plan:
- Longer recharge durations: There are a few different types of long expiry prepaid options. The most common is the 365-day recharge, but there are also 90-day and 180-day options. Every now and then, telcos will off one-year recharge options, which won't necessarily last you 365 days; instead they expire on a year from the day you activate.
- Better dollars-to-data value: The easiest way to compare long expiry prepaid options is to calculate the equivalent monthly cost and inclusions. This allows you to compare 180-day and 365-day recharge options in a like-for-like way. For example, if a 365-day plan offers 300GB of data over the year for an annual $300 payment, that works out equivalent to 25GB per month for $25 per month, or $1 per 1GB. Whereas a $250 plan that offers 215GB would be equivalent to paying roughly $20.90 per month for roughly 18GB of monthly data, or about $1.20 per GB.
- Data rollover: Different telcos offer different data rollover offers (some don't offer it at all). Some allow you to bank a limited amount of unused data for your next recharge, others let you roll over all of your unused data if you recharge before the expiry date. It's important to know which data rollover or data banking option is available to you before signing up.
- Auto-recharge with no excess data fees: Again, different telcos have different ways of handling excess data charges. Some will simply charge a per-megabyte rate for all data used in excess of your inclusions, deducting that amount from the dollar value of your recharge amount. Others offer convenient auto-recharge options that automatically top up your balance via direct debit when you run out of credit or your plan expires.
Expert Advice
"365-day long expiry plans can be an excellent choice for mobile customers who use very little data each month and want to save by paying a bigger amount up front."

While 365 day and 1 year prepaid phone plans do command an expensive upfront cost, they can sometimes work out to be cheaper than their month-to-month counterparts. However, the downside of this affordability is that they tend to offer significantly less value from a dollars-per-gigabyte perspective. You're paying less, but you aren't getting as much for your money.
Long expiry, 365 day and 1 year prepaid phone plans are great for those who don't use that much data or like the idea of locking in the cost of their phone bill ahead of time. However, they aren't necessarily going to be the right for everyone as monthly SIM-only plans can offer significantly more data, perks and flexibility.
At the time of writing, there are no long expiry prepaid plans with unlimited data. If you do want excess-charge-free or unmetered data, you'll have to go with a postpaid provider like Felix or Dodo.
No. Unfortunately, every prepaid mobile plan in Australia has some sort of timeline on when it will expire. If you're keen to put off having to think about your mobile plan for as long as possible, a 365-day long expiry plan like the ones featured on this page may be the best choice.
Typically, Aussies signed up for a long expiry prepaid mobile plan like the ones featured on this page lose any remaining or unused data once their expiry date arrives. However, some providers offer a form of data banking or data rollover. So long as you meet that (and any other) criteria, some amount of your data will carry over into your next recharge.
