Saily does not provide a true unlimited high‑speed data eSIM for Australia; every Australian plan shown in the catalog has a definite data cap (for example, 5 GB/day, 20 GB, or 25 GB). Once a plan’s limit is reached, the network speed is reduced—from 1 kbps in some “Unlimited”‑named plans to 1024 kbps in others—so full‑speed data is not available without restriction.
For travelers who need more data without the speed penalty, Saily offers fixed‑data options such as the Australia 20 GB 30 day plan priced at $29.99 USD and the Asia and Oceania 25 GB 60 day plan at $48.99 USD. These plans provide larger data allowances and can be more cost‑effective for most users, although a truly unlimited plan is not available.
