Get an Australian number before almost anything else: employers call it, your bank texts codes to it, and your PayID is built on it. The trap unique to Australia is coverage, which thins fast outside the cities, so if you are heading bush for regional work the network you pick matters more than the price. The budget providers below run on the big networks for a fraction of the cost.
Australia has three mobile networks: Telstra, Optus and Vodafone. Buy a prepaid SIM or eSIM from a budget provider on the Telstra or Optus network for city life. If you're heading regional for farm work, pay for Telstra-network coverage (Telstra itself or Boost Mobile). An international travel eSIM covers your first days; switch to a local SIM once you're settled.
A local number unlocks banking, job applications and ID checks — sort it in your first days in Australia.
Every Australian provider runs on one of three networks:
| Network | Coverage | Relative price | Budget brands on it |
|---|---|---|---|
| Telstra | Widest; best for regional and farm areas | Highest | Boost Mobile (full network), ALDImobile (wholesale) |
| Optus | Strong in cities and most towns | Mid | amaysim |
| Vodafone | Cities and major corridors | Lowest | Various smaller brands |
The big three sell their own plans, but dozens of smaller brands (MVNOs) resell the same networks for less. The ones most relevant to working holidaymakers:
All three major networks support eSIM, and most of the budget brands do too. (WHE Verification Tracker, verified June 2026.)
Before you commit to a provider, check its coverage map for the actual region you're heading to. Every provider publishes one. If you don't know where you'll end up, a Telstra-network prepaid (Boost, ALDImobile, or Telstra itself) keeps your options open. You can always switch later; prepaid means no contract.
If your phone supports eSIM, you can land with data already working. Two ways to do it:
Providers such as Airalo and Holafly sell Australian data eSIMs you install before you fly. You'll have data the moment you switch off flight mode, which makes the airport-to-hostel run easier (maps, rideshare, telling people you're alive). They're data-only and cost more per gigabyte than local prepaid, so treat them as a bridge for your first days, not a long-term plan.
Telstra, Optus, Vodafone and most budget brands can issue your plan as an eSIM, usually activated through their app. Same price as physical SIM, no store visit needed.
You'll still want a proper Australian number quickly. Employers, banks, real estate agents and government services all expect one.
Prepaid SIMs are sold everywhere: supermarkets (Coles, Woolworths, ALDI), convenience stores, airports and carrier stores. Starter packs are cheap; you pay for the recharge plan.
One legal requirement to know: since 2017, Australian law has required providers to verify your identity before activating any prepaid mobile service, SIM or eSIM. You'll do this during activation, normally online with a government-issued ID such as your passport (ACMA, ID checks for prepaid mobiles). It takes minutes, but do it somewhere with wifi.
Prepaid plans typically run on 28-day recharge cycles, so a "monthly" price renews 13 times a year, not 12. Prices change often; compare the data per recharge on the provider sites rather than relying on any published figure.
Prepaid, almost always. Postpaid plans can require credit checks and lock you into terms that outlast your visa. Prepaid gives you the same network, no exit problem, and the freedom to switch providers when you move regions. If you stay long-term and want a phone upgrade, revisit it then.
Hostels and cafes in cities have decent wifi. Farm accommodation often has none. If you'll work regionally, your phone plan is your internet, so size the data allowance accordingly, or ask the employer what coverage is like before you accept.
The emergency number is 000 (112 also works from any mobile, even without a SIM or signal from your own network). Save both. (WHE Verification Tracker, verified June 2026.)
