How Much Does Microsoft 365 Cost in Australia in 2026?

If you've tried to find a straight answer on Microsoft 365 pricing in Australia, you've probably run into a wall of USD figures, confusing plan names, and add-on fees that weren't mentioned upfront. This guide cuts through all of that.

We'll cover the current AUD pricing for the three main Business plans, exactly what you get with each, the costs most businesses don't account for, and how to pick the right plan without overpaying.

The Three Microsoft 365 Business Plans

Microsoft offers three primary plans for businesses with fewer than 300 users. Here's the 2026 pricing in Australian dollars:

What's Actually Included in Each Plan

Business Basic (~$8.60/user/month)

Basic is Microsoft's entry-level plan. It includes:

• Web and mobile versions of Word, Excel, PowerPoint, and Outlook
• Microsoft Teams (chat, video, calls)
• Exchange Online (business email with your domain)
• SharePoint and OneDrive (1TB per user)
• Microsoft Forms, Planner, and To Do

What it does NOT include: desktop versions of Office apps. Your staff use Word and Excel in a browser only. For many office workers this is fine; for power users it's frustrating.

Business Standard (~$21.60/user/month)

Standard adds the full desktop Office suite on top of everything in Basic:

• Desktop apps: Word, Excel, PowerPoint, Outlook, OneNote, Access (PC only), Publisher (PC only)
• Install on up to 5 PCs/Macs, 5 tablets, and 5 phones per user
• Microsoft Bookings (appointment scheduling)
• Webinar hosting via Teams

This is the plan we recommend for most Sydney businesses. The desktop apps alone justify the price difference over Basic for anyone doing serious document work.

Business Premium (~$36.90/user/month)

Premium includes everything in Standard plus Microsoft's advanced security and device management tools:

• Microsoft Defender for Business (enterprise-grade endpoint protection)
• Intune (mobile device management — manage company devices centrally)
• Azure AD Premium P1 (conditional access, advanced identity protection)
• Information protection and data loss prevention (DLP) policies
• Microsoft Purview (compliance tools)

If your business handles sensitive client data — legal, medical, financial, or accounting — Premium is worth every cent. The Defender and Intune tools alone would cost more to licence separately.

The Costs Most Businesses Don't Budget For

The per-user monthly fee is just one part of the total cost. Here's what often catches businesses off guard:

Migration costs

Moving from Gmail, on-premise Exchange, or another mail provider to Microsoft 365 takes time and expertise. A proper migration for a 20-person business typically takes 1–2 weeks of work. If you attempt it yourself and something goes wrong, you risk email downtime and data loss. Budget for a professional migration unless you have in-house IT capacity.

Setup and configuration

Out of the box, Microsoft 365 is not secure. Default settings allow too much external sharing, have no MFA enforced, and leave Defender unconfigured. A proper security baseline configuration — enabling MFA, setting conditional access policies, configuring DLP rules — typically takes 4–8 hours for a new tenant.

Ongoing administration time

Someone needs to manage user provisioning, licence assignments, password resets, and security incidents. For a business of 20 staff, this is roughly 3–5 hours per month of admin work. If that's falling on a non-IT person, it's usually done poorly (or not at all).

Add-on licences

Microsoft Teams Phone (calling plan), Microsoft 365 Backup, Copilot for Microsoft 365 ($65 AUD/user/month), and Power BI Pro are all charged separately on top of your base plan.

Microsoft 365 vs a Perpetual Office Licence

Some business owners ask: “Why not just buy Office 2021 outright?” It's a fair question. A perpetual licence for Office Home & Business 2021 costs around $450 AUD per PC, once.

The case for Microsoft 365 over perpetual:

• Always on the latest version (Office 2021 is already behind)
• Exchange Online — hosted business email with 50GB mailbox included
• Teams, SharePoint, OneDrive, and the rest of the productivity suite
• Install on multiple devices per user
• Security features in Premium that don't exist in any perpetual licence

For most businesses with more than 5 staff, Microsoft 365 is the right choice. The email and collaboration tools alone make the maths work.

How to Avoid Overpaying

The most common mistake we see during Microsoft 365 audits is over-licencing. Businesses often put every user on Premium when half of them only need Basic. A few staff members might be casuals or contractors who don't need email at all.

A quick way to right-size your licencing:

• List every user and what they actually use Microsoft 365 for
• Put power users and anyone handling sensitive data on Premium
• Put standard office staff on Standard
• Put meeting-room accounts, shared mailboxes, and light users on Basic
• Remove licences for staff who have left (this is the most common source of waste)

A 25-person business on mixed licensing (10 Premium, 10 Standard, 5 Basic) pays roughly $615/month. The same business with everyone on Premium pays $920/month — a difference of over $3,600 per year for no additional benefit to most users.

How a Managed Microsoft 365 Service Changes the Equation

When ITEC HELP manages your Microsoft 365 environment, the per-user licence cost is the same — but you also get:

• Licence management and cost optimisation handled for you
• Security baseline configured and maintained
• User provisioning and offboarding managed same-day
• Help desk support for Teams, Outlook, and SharePoint issues
• Monthly security health checks on your tenant

For most businesses, the time saved on administration and the risk avoided from misconfiguration more than justifies the managed service fee.
