The short answer
Get a local SIM on day one and home internet sorted in your first week — both are straightforward.
Prepaid vs postpaid
Prepaid — pay upfront, no contract, no credit check. Plans commonly run ~A$10–30/month with generous data. Ideal for newcomers.
Postpaid — monthly billing, usually 12–24 month terms, often bundled with a handset. Requires ID and sometimes a credit check.
The three networks and the budget carriers
Australia has three mobile networks: Telstra (widest coverage, especially regional), Optus, and Vodafone. Budget carriers (MVNOs) resell access on these networks — e.g. Amaysim and Boost Mobile, which runs on the Telstra network — usually at lower prices. If you'll travel outside major cities, network coverage matters more than price.
What to buy in your first week
Buy a prepaid SIM at the airport, a supermarket, or a convenience store — you'll need photo ID (passport works). Compare data allowances rather than headline prices; most newcomers do fine on a mid-tier prepaid plan. eSIM options exist with major carriers if your phone supports them.
Home internet: the NBN
Most fixed home internet runs over the National Broadband Network (NBN). The NBN wholesales the network; retail providers sell you the plan, tiered by speed. Typical considerations: choose a speed tier that fits your household, check whether a modem/router is included or must be bought, and prefer no-lock-in contracts while you're settling in. Plan prices and inclusions change often — compare current offers before signing.
Free Wi-Fi
Free Wi-Fi is common in Australian cities: public libraries, many cafes, shopping centres, airports, and some public transport hubs. Useful as a backup, but don't rely on it for banking or sensitive logins.
Frequently asked questions
Which carrier has the best coverage?
Telstra's network is generally regarded as the widest, particularly outside cities. In metro areas all three networks perform well.
Can I keep my foreign phone number?
Yes for messaging apps tied to it, but you'll want an Australian number for job applications, banking verification codes, and two-factor authentication.
Do I need a contract for home internet?
No — many NBN retailers offer no-lock-in monthly plans, which suit newcomers.
How much data do I need?
Light users manage on small prepaid data packs; if you'll hotspot a laptop, choose a larger allowance. Monitor your first month's usage, then adjust.
