Mobile 365-Day Long-Expiry Phone Plans
Every 365-day (and near-365-day) prepaid SIM plan available in Australia — including six plan tiers that rarely show up on comparison sites, like Telstra's and Optus's own direct plans, and Telsim's long-expiry SIMs — cross-checked against independent, publicly posted buyer ratings.

Figures are full-year totals. "Total data" is what you actually get across the whole 365 days, and "~$/GB/Month" is priced off the ongoing recharge, not the cheaper year-one rate.

If you're choosing today
Kogan Mobile is the only provider here with both real review volume and a rating people would call good. Runs on Vodafone's network — check coverage at your specific address first. Its "no rollover" data structure (30-day blocks even on the 365-day plan) is the one catch worth knowing before you buy.
Boost or ALDI Mobile if you want the full Telstra network under a cheap long-expiry SIM. Both sit around 1.9★, but the complaints are almost entirely about the sign-up call and billing portal, not coverage once the SIM is working.
Lycamobile Large at $0.53/GB ongoing (900GB/year for $480) is the cheapest data on this whole list, on a lower 2.2★ rating driven mostly by slow refunds and long hold times.
Going direct to Telstra or Optus buys you nothing. Their own long-expiry plans (1.4★ and 1.3★, the two worst in this whole search) cost more per GB than the MVNOs riding their exact same towers. Vodafone's direct plan (1.5★) has the same problem versus Lebara and Lycamobile.
