Choosing a mobile phone plan in Australia is straightforward once you understand the Big Three carriers and budget alternatives (MVNOs). Here’s a breakdown of costs, coverage, and which plan suits your needs.
The Australian Mobile Market
Three major carriers (Big Three):
- Telstra: Largest; best regional coverage.
- Optus: Second-largest; strong in cities; cheaper than Telstra.
- Vodafone: Smallest; budget-focused; mainly urban coverage.
MVNOs (Mobile Virtual Network Operators): Smaller companies that lease network from the Big Three and offer cheaper plans. Examples: Boost, amaysim, ALDImobile, Belong, Aldi Mobile.

Bringing Your Own Phone vs Buying in Australia
Option 1: Bring Your Phone from Home
Advantages:
- No cost.
- Familiar device.
- Potentially better specs than budget Australian phones.
Requirements:
- Phone must be “unlocked” (not tied to your home country carrier).
- Contact your home carrier before departure to unlock it.
- Check it’s compatible with Australian networks (4G/5G bands match).
Cost: Usually free (unlock is often complimentary or A$50–$100 if charged).
Option 2: Buy a Cheap Phone in Australia
Budget options:
- Telstra Smart S10: A$200–$300 (basic, adequate for students).
- Samsung A series: A$400–$600 (mid-range, reliable).
- iPhone SE: A$800–$1,000 (premium but cheaper than latest models).
Available at JB Hi-Fi, Harvey Norman, The Good Guys, or carrier stores.
Reality: Phones are cheaper in Australia than many countries. Consider buying if your home phone is very old.
Getting a Local Phone Number
When you activate a SIM, you’re assigned an Australian phone number automatically. Format: +61 [2–8] [area code] [number].
Example: Sydney number is +61 2 [local number].
What it means:
- Your family/friends can text/call you on this Australian number.
- Calls from Australia to your number are local rates.
- International calls/SMS are expensive (A$1–$3/minute typically).
Alternative: Use WhatsApp, Viber, Telegram for free international calls (data-based).
International Calling and Roaming

Costs (from Australia to overseas):
- Telstra: A$2–$5/minute (expensive).
