With millions of Australians now able to access 5G, more of are gravitating towards mobile plans boasting faster network speeds. If you're one of these people, you've come to the right place because we've rounded up the most affordable 5G mobile plans, as well as picks paired with the iPhone 17 and Galaxy S26.
When picking the best 5G mobile plans, we're looking for the best bang-for-buck deals; plans that get you the most data possible in each given price category. For most categories, we consider both postpaid and prepaid options. The exception to this is iPhone 17 and Galaxy S25 plans, as new phones can't be paired with a prepaid plan.
Best 5G mobile plans by price
While you won't find 5G on every single mobile plan in Australia, it is now very common. Most providers offer some plans with 5G connectivity across a whole range of price points.
Take a look at the 5G mobile plans in our database with the most data in each price category below. The top result in each table is the current plan that offers you the maximum amount of data you'll get for that spend.
Just note most of these plans will have a speed limit. Cheaper 5G plans are typically capped to download speeds of 100Mbps, 150Mbps, or 250Mbps. By and large, this is still more than fast enough for typical mobile usage.
- Most data for under $30 per month (for at least six months after signing up)
- Unlimited talk and text
- Prepaid and postpaid mobile plans considered
- Most data for between $31 and $40 per month (for at least six months after signing up)

When plans have similar inclusions, the cheapest option isn’t always the best. One way to compare is on the value per GB. As a rule of thumb, anything at $1 or under per GB is good value.
Best 5G mobile plan with uncapped speeds
Many cheaper 5G plans have speed caps - they're typically limited to between 100Mbps and 250Mbps - so for this category, we're only looking at uncapped plans. This means the plans can operate as fast as network conditions allow. When testing 5G on an uncapped plan, we've seen speeds between 500Mbps and 1Gbps.
Because we know you need a lot of data to go with those fast 5G speeds, we only considered plans with at least 50GB of full-speed data in this category. Check out the cheapest plans in our database that meet this criteria below.
- Cheapest plan price in our database (for at least six months after signing up)

If you have a 5G-ready plan from your existing provider, you do not need a new SIM card for 5G. However, if you're swapping providers to get a 5G-ready plan, your new provider will send you a new SIM card.

WhistleOut is Australia's telco comparison website, founded to help everyday Aussies find a phone and internet plan that's right for them. As part of our service promise, we're committed to listing plans from at least the top ten providers of mobile plans in the market, but we're currently tracking 28.
When we have a commercial relationship with a provider, you'll see a "Go To Site" button that takes you straight to that plan. We still compare plans from providers we don't have a commercial relationship with, but these don't have a button. To keep our listings up to date, we have a dedicated product team that makes around 400 changes to our database each month.
