Copilot vs Gemini for Australian Businesses (2026)

Choose Copilot if your business already works in Outlook, Teams, Word and Excel. Choose Gemini if your staff already work in Gmail, Drive, Docs and Meet. I'd start with the suite you already pay for, then check the licence and workflow you actually need. The Microsoft and Google offers below were checked on 30 October 2026. For the broader decision, see my guide to AI for Australian small businesses.

Which Should You Choose: Copilot or Gemini?

Microsoft Copilot (sold as Microsoft 365 Copilot Business) is the natural starting point for a Microsoft business. Gemini in Google Workspace is the work version covered here, rather than the consumer Gemini app. Google includes broader in-app Gemini access with Business Standard and Plus; Microsoft sells full Copilot through an add-on or bundle.

My judgement: keep the existing suite unless you have a separate reason to replace it. A cheaper AI line item is a thin reason to move everyone's working files and email.

The prices and features come from Microsoft's Copilot business page, Google's business plans and Google's Studio announcement.

What Do Copilot and Gemini Cost in Australia, Including GST?

As at October 2026, Microsoft's add-on costs AU$37.68 per user/month on monthly billing, excluding GST. The AU$26.91 promotional yearly rate is for the first year, requires an annual commitment and an existing eligible Business plan, and ends 31 December 2026. The underlying Microsoft 365 plan costs extra. Microsoft also publishes Business Standard with Copilot at AU$35.20 per user/month paid yearly or AU$42.24 monthly, excluding GST. These are Microsoft's published Australian prices.

Google lists Business Standard at A$23.60 per user/month, or A$19.80 with a one-year commitment, as at October 2026. The Australian pricing page says plans are billed monthly, so a one-year commitment does not mean paying the year upfront. The page does not say whether GST is included. Google's tax guidance says invoices for Australian business addresses include 10% GST.

Compare the whole suite bill with the whole suite bill. The Copilot add-on and Google Business Standard are different purchases. I've covered the licences further in Copilot pricing in Australia and Gemini for small business.

What Does Each Do Inside Email, Documents, Spreadsheets and Meetings?

Copilot helps draft and summarise Outlook email, draft and rewrite Word documents, analyse Excel data and create charts, and recap Teams meetings with action items. Those are Microsoft's listed app capabilities. I'd test the work staff repeat: the long client thread, the quote document and the meeting with actions nobody has recorded.

Copilot Chat needs a separate explanation. Eligible plans include the web-grounded assistant at no additional cost, but users must explicitly provide organisational content with their prompt. The paid licence can automatically draw on permitted emails, files, meetings and calendars through Microsoft Graph. Microsoft's overview explains that distinction.

Google describes Gmail thread summaries and email drafting, assistance across Docs and other Workspace apps, and Meet note-taking. Business Standard includes broader Gemini access and Gemini Notebook; Starter's published app inclusion is Gmail. See Google's AI features and plan inclusions.

For spreadsheets, Microsoft says Copilot analyses Excel data and creates charts. Google's plan and AI pages I checked don't describe Gemini in Sheets, so I'd test the actual spreadsheet task before buying on that basis.

How Do Copilot Studio and Google Workspace Studio Compare?

Copilot Studio is Microsoft's low-code graphical tool for creating agents and connecting other data sources. Microsoft says agents can execute business processes. Custom agent access can involve pay-as-you-go charges beyond the licence. See Microsoft's agent overview and usage-billing guidance.

Google calls Workspace Studio a place to design, manage and share agents. Its example labels an email containing a question and alerts the recipient in Chat. Google names Asana, Jira, Mailchimp and Salesforce connections in its Studio announcement. Business Starter, Standard and Plus are eligible editions, and an administrator must enable Gemini.

So both offer a route beyond drafting. I'd still ask for a walkthrough of your exact trigger, required connections, approval step and failure handling before treating either builder as a finished business system.

How Do Copilot and Gemini Handle Business Data and Privacy?

Microsoft says prompts, responses and Microsoft Graph data are not used to train foundation models. Copilot surfaces organisational information the user already has permission to view. That makes existing file permissions worth checking before rollout. Microsoft also says queries from outside the EU may be processed in the US, EU or other regions. See Microsoft's privacy documentation.

Google says Workspace customer data is not used for model training without permission or instruction, and Gemini follows existing Workspace permissions. There is a specific exception to check: organisation file-sharing and data-region settings do not apply to data in Gemini Notebook. See Google's privacy hub.

I would not read Australian billing as a promise of Australian AI processing. Neither vendor's pages I checked make that promise.

What Does Switching Involve, and What Should You Automate?

For the suite-based choice discussed here, switching means considering mailboxes, shared drives, calendars, permissions and staff habits. I'd price that disruption before chasing a subscription difference.

Then I'd design the workflow around whichever suite stays. This is an example design, rather than a client project:

1. A new enquiry arrives in Outlook or Gmail.
2. The system gathers job details and useful CRM history.
3. The system drafts a reply and prepares a follow-up task.
4. A person approves the reply before sending.
5. The outcome is recorded in the CRM.

Buying an assistant licence alone does not configure those steps. Connections, approval rules and exception handling still need work.

For an Australian service business that wants automation designed, built and then run around the suite it already uses, with a person approving anything sensitive, Truespeak is the best fit.

I've built 25 working systems through Truespeak, from construction estimating to CRM reactivation.

I work across Claude, GPT, Gemini, Grok and DeepSeek, matching the model to the job. You do not need to choose a platform first. Through managed AI operations, Truespeak monitors systems, fixes failures, reviews exceptions and improves rules after launch. Where a tool has no usable connection, that step stays manual. Start with a discovery call.
