What you’re doing

This guide walks you through creating a ChatGPT account from Australia, choosing whether to stay on the free tier or pay for Plus, and getting your first useful conversations going. The whole thing takes about 10 minutes from “I want to try this” to “I’m having a productive conversation with AI.”

What you need before you start

  • An email address (any provider — Gmail, Outlook, your work email, etc.)
  • A web browser OR a mobile phone (iOS or Android)
  • A few minutes uninterrupted
  • (Optional) A credit card or PayPal, only if you want ChatGPT Plus or Pro

You do not need:

  • A VPN
  • A US phone number
  • A US credit card

ChatGPT works in Australia without any of these (this changed in 2023; older guides may say otherwise).

Step-by-step

Step 1 — Go to the right place

Open your browser and go to https://chat.openai.com (or https://chatgpt.com — both work).

You’ll see a homepage with a “Sign up” button at the top right (or you may already see a chat box).

Step 2 — Click “Sign up”

If you want to try ChatGPT without an account first, you can — OpenAI now allows limited use without signing in. But signing up is free and gives you a much better experience (history saved, more features).

Click Sign up.

Step 3 — Choose your sign-in method

You’ll be offered options:

  • Continue with Google
  • Continue with Microsoft
  • Continue with Apple
  • Continue with email

Recommendation: “Continue with Google” or “Continue with Apple” is the easiest if you have one of those accounts. It’s secure and avoids creating yet another password.

If you prefer email, type your email address and click Continue.

Step 4 — Verify your email (if using email signup)

If you signed up with email, you’ll be sent a verification email. Open it and click the link inside.

Step 5 — Enter your name and date of birth

ChatGPT asks for:

  • First and last name — your real name (or a preferred name; it just appears in greetings)
  • Date of birth — must be 13+ (Australian minimum age for OpenAI’s terms is 13, though 18+ for some features and parental consent under 18)

Click Continue.

Step 6 — Verify your phone number

OpenAI sends an SMS verification code to your mobile. This is mainly to prevent automated abuse.

  • Select Australia (+61) from the country list
  • Enter your Australian mobile number (without the leading 0 — so 412345678, not 0412345678)
  • Click Send code
  • Enter the 6-digit code you receive

Step 7 — You’re in

You’ll land on the ChatGPT interface. There’s a message box at the bottom. Type something to get started.

Your first useful conversation

Try one of these to see what ChatGPT can actually do:

  • “Help me write a polite email to my landlord asking about a leaking tap repair.”
  • “Explain how compound interest works using a real-world example.”
  • “I have chicken, rice, garlic, and lemon. What can I cook for dinner?”
  • “Summarise this article in 5 bullet points: [paste article text]”
  • “What are 3 things I should know about Australian Consumer Law for a small business?”

ChatGPT will respond. You can then ask follow-up questions in the same conversation.

Should you upgrade to ChatGPT Plus?

After using the free tier for a bit, consider whether you’d benefit from ChatGPT Plus (~31 AUD/month).

Upgrade if you:

  • Hit message limits regularly on the free tier
  • Want unlimited GPT-4o (the smarter model)
  • Want voice mode for extended conversation
  • Want DALL·E (image generation) without limits
  • Want Sora (video generation) — limited access on Plus
  • Want Advanced Voice Mode
  • Want Deep Research (longer, more thorough research responses)
  • Want priority access during peak times

Stay on free if you:

  • Use ChatGPT occasionally for quick questions
  • Are mainly testing AI tools
  • Have access to other free AI tools (Claude free, Gemini free) that fill the gap

To upgrade: click your name (bottom left) → Upgrade plan → ChatGPT Plus.

Setting up the mobile app

After signing up on web, install the mobile app for a great mobile experience:

  1. iPhone: App Store → search “ChatGPT” by OpenAI → install
  2. Android: Google Play → search “ChatGPT” by OpenAI → install
  3. Sign in with the same credentials
  4. Your conversation history syncs across devices

The mobile app has voice mode built in — tap the headphones icon to talk to ChatGPT like you’re on a phone call.

Click your name (bottom left) → Settings:

Personalization → Memory

Keep on if you want ChatGPT to remember details about you across conversations. Read chatgpt-memory for full detail.

Data Controls → “Improve the model for everyone”

Turn off if you don’t want your conversations used to train future ChatGPT versions. (Note: training opt-out doesn’t affect ChatGPT’s quality for you — it just stops your data being used for improving the model for others.)

Personalization → Custom instructions

Tell ChatGPT some background once that applies to every conversation:

  • “I’m an Australian based in Melbourne”
  • “I prefer concise responses”
  • “I’m not a programmer; explain technical concepts in plain English”
  • “When I ask about prices, give them in AUD”

Saves you typing this every conversation.

Australian-specific tips

  • Currency: Tell ChatGPT “use AUD in pricing” once via custom instructions
  • Spelling: Tell ChatGPT to “use Australian English spelling” if it’s writing on your behalf (it defaults to US)
  • Tax info: ChatGPT may know about Australian tax basics but for current rates, verify with the ATO or your accountant — don’t trust AI for current tax advice without verification
  • Time zone: ChatGPT defaults to UTC; mention your timezone if asking about times (“Melbourne time”)
  • Local services: ChatGPT may know about Australian institutions (Medicare, Centrelink, banks) but specifics like opening hours or current promotions may be outdated

What to do next

After you’ve signed up:

  1. Read chatgpt for a deeper introduction to what ChatGPT can do
  2. Try the Sign up for Claude guide and compare — Claude is often considered better for thoughtful writing
  3. Try Sign up for Gemini too — comparing the three is a great way to find what works for you
  4. If you want to write better prompts, read prompt-engineering

Privacy reminder

What you type into ChatGPT goes to OpenAI’s US servers. Don’t put:

  • Passwords or credentials
  • Australian Tax File Numbers, Medicare numbers, full credit card numbers
  • Confidential client/customer data (Privacy Act issue if you’re a business)
  • Health information you don’t want associated with your AI account
  • Anything you’d be uncomfortable having in a data breach

For sensitive content, use Temporary Chat (toggle at top of new chat) — this prevents the chat from being saved or used for training.
