Quick answer: There’s no single “best” prepaid plan; the top rated prepaid plans depend on your usage. This guide rounds up the best prepaid options across major providers so you can compare prepaid mobile plans side by side:
- Want strong coverage + data rollover? Telstra’s 20GB ($44) or 35GB ($54) 28-Day Plans
- Want the most data for your money? TPG or Kogan’s high-data plans
- Want to recharge less often? Telstra’s 6-month or 12-month Plan
- Barely use data? Telstra’s $15 7-Day Plan or Casual Plan
We’ve broken down price, data, coverage, expiry, and rollover across the best prepaid phone plans on the market, so you can match a plan to how you actually use your phone.
What Makes a Prepaid Plan Good Value?
The cheapest or biggest plan isn’t automatically the best one. Before you compare prepaid mobile plans, focus on these four things:
- Cost per gigabyte: a $20/120GB plan looks better than a $44/20GB plan, until you realise you only use 10GB a month. Match the plan to your actual usage.
- Network coverage: a cheap plan is useless if it drops out at home or on your commute. Matters most outside major cities.
- Expiry length: a 28-day cycle means 13 recharges a year, not 12. Long-expiry plans trade a higher upfront cost for fewer recharges.
- Data rollover: some plans let unused data carry over instead of vanishing at expiry; this can make a smaller plan outperform a bigger one.
3 Types of Prepaid Mobile Plans in Australia
1. Standard 28-Day/Monthly Plans: one of the best prepaid options with fixed data, calls and texts, renewing every 28 days or on a calendar month.
Watch out: 28-day cycles cost more per year than true monthly plans.
2. Long-Expiry Plans (60–365 days): a bigger upfront payment for data that lasts far longer, good for anyone who’d rather not think about recharging.
3. Pay As You Go: charged per call, text, or MB used. Best for very light or emergency-only use; rarely best value if you’re online daily.
Best Prepaid Mobile Plans Australia for Medium Data Users (15GB–30GB/month)
Telstra’s $44 28-Day Plan gives 20GB, and the $54 plan steps up to 35GB. Both include Continuous Data Rollover (up to 200GB) and unlimited standard Aussie calls and texts.
| Provider | Plan | Data | Price | Network |
| Telstra | $44 28-Day Plan | 20GB | $44 | Telstra |
| Telstra | $54 28-Day Plan | 35GB | $54 | Telstra |
| TPG | 25GB Small Plan | 25GB | $12.50/month for 6 months, then $25 | Vodafone |
| SpinTel | $23 Mobile Plan | 25GB | $12/month for 6 months, then $23 | Optus |
| Dodo | Medium Mobile Plan | 40GB | $15/month for 6 months, then $30 | Vodafone |
Bottom line: Choose Telstra if coverage matters more than price (especially regionally). Choose TPG, SpinTel or Dodo if your area has strong Optus/Vodafone reception and you want to save money. These sit among the top rated prepaid plans for everyday users who don’t need huge data allowances.
Best Prepaid Phone Plans for Heavy Data Users (30GB+/month)
| Provider | Plan | Data | Price |
| TPG | 50GB Medium | 50GB | $17.50/mth for 6 mths, then $35 |
| Kogan Mobile | Large Monthly | 120GB initially | $20 per 30 days, then 80GB |
| Boost Mobile | $39 Prepaid | 60GB (first 6 recharges) | $39 per 28 days, then 30GB |
| TPG | 100GB Large | 100GB | $22.50/mth for 6 mths, then $45 |
| Exetel | Plus One eSIM | 130GB | $40 per 30 days |
Bottom line: TPG’s 50GB plan is a standout for price-to-data ratio and one of the best prepaid phone plans for value right now. Don’t pay for 100GB+ if you only use 20–30GB; check your actual usage first.
Promotional pricing has eligibility conditions and end dates. Always confirm current terms before signing up to any best prepaid offers.
Best Prepaid Options for Casual & Short-Term Users
If you rarely use your phone as a spare handset, backup SIM, or travel device, a big monthly plan is wasted money.
Telstra runs two products for light use:
- Telstra $15 7-Day Plan (4GB, built for travellers or backup phones)
- Telstra Pre-Paid Casual Plan ($44, 1GB, 120 call minutes, 150 texts, longer expiry for calls than data).
Good for: travellers, backup phones, emergency handsets, temporary numbers, Wi-Fi-only devices.
Watch out: short expiry plans look cheap but can cost more overall if you’re recharging constantly. Compare the best prepaid offers carefully before locking in a short-term plan.
Long-Expiry & 365-Day Plans
| Telstra Plan | Data | Price | Cost per month (approx.) |
| 6-Month Plan | 80GB | $200 | ~$33.33 |
| 12-Month Plan | 180GB | $395 | ~$32.92 |
Best for: spare phones, tablets, kids’ phones, low-moderate users, or anyone who hates recharge reminders.
Trade-off: higher upfront cost and less flexibility if your needs change.
Why Coverage Beats the Sticker Price
Price tells you what you pay; coverage tells you whether the plan works where you need it.
- Telstra states its network covers more of Australia than any other provider, with 5G reaching 85% of Australians on a compatible device.
- Plans from other providers often run on shared/wholesale networks, where coverage and speed can vary.
Regional users, check:
- Coverage at home, work, and places you visit often
- Coverage along regular travel routes
- Actual (not just advertised) speeds; congestion, distance from towers, and your device all affect this
Don’t Overlook Speed Caps
Not all plans on the same network get the same speed:
| Telstra 28-Day Plan | Speed Cap |
| $44 / $54 plans | 150Mbps |
| $64 plan | 250Mbps |
| $74 plan | Uncapped |
Do you need faster than 150Mbps? Only if you regularly download large files, hotspot multiple devices, or stream a lot of high-quality video. For everyday use, 150Mbps is plenty.
Data Rollover: Small Feature, Real Value
Eligible Telstra Prepaid Mobile plans, including selected 28-Day Pre-Paid Plans, let you carry forward unused data (up to 200GB) when you recharge on time.
Why it matters: a smaller plan with rollover can beat a bigger plan that wipes unused data every cycle, especially if your usage varies month to month.
Watch out: Not all long-expiry plans include rollover; always check before buying.
Common Mistakes to Avoid When Comparing Prepaid Mobile Plans
- Comparing only the intro price: most deals revert to a higher rate after 3–6 months. Check the “then” price.
- Chasing data you won’t use: more GB isn’t more value if you never touch it.
- Ignoring the expiry cycle: a 28-day plan costs more per year than a genuine monthly one.
- Skipping coverage checks: a cheap plan is worthless if it drops out at home, at work, or on your commute.
- Assuming long-expiry plans include rollover: many don’t. Confirm before you pay upfront.
- Overlooking speed caps: a cheaper plan on the same network can be throttled well below a pricier tier.
Which Plan Should You Choose?
| Your usage | Best fit |
| Under 10GB/month | Low-cost or casual plan |
| 15–30GB/month | Medium-data plan: prioritise coverage + rollover |
| 30GB+/month | High-data plan (TPG, Kogan, etc.) |
| Rarely want to recharge | 6-month or 365-day plan |
| Live in a regional area | Prioritise coverage over price |
The takeaway: among the best prepaid mobile plans Australia has to offer, the right one gives you enough data, reliable coverage and useful features without paying for more than you’ll use. If you prefer the predictability of paying for your mobile service upfront rather than recharging regularly, you may also want to compare Telstra Upfront Mobile Plans with prepaid options to see which better suits your budget and usage. Compare total cost over time, not just the intro deal, and you’ll land on one of the genuinely top rated prepaid plans for your situation.
