The short version
- 01Microsoft Azure and AWS both run cloud regions in Sydney and Melbourne, so most Australian businesses can keep data onshore.
- 02Keeping personal information in Australia makes Privacy Act obligations around overseas disclosure much simpler to manage.
- 03Choose a region for resilience as well as location — and keep backups in a second one.
Most cloud migration conversations start with cost and features. We think they should start with a simpler question: where will the data actually be? It shapes your privacy obligations, how quickly systems respond for your team, and what happens if a data centre has a bad day.
What a cloud region is#
A region is a group of data centres in one geographic area. When you create a server, database or storage account, you choose its region — and that’s where the data is stored unless you configure it to be copied elsewhere.
Some regions are split into availability zones: separate data centres with independent power, cooling and networking, so a failure in one doesn’t take everything down. Not every region offers them, which is worth checking before you commit.
Australian regions at a glance#
| Provider | Region | Location |
|---|---|---|
| Microsoft Azure | Australia East | Sydney, NSW |
| Microsoft Azure | Australia Southeast | Melbourne, VIC |
| Microsoft Azure | Australia Central and Central 2 | Canberra, ACT — designed for government and critical infrastructure |
| AWS | Asia Pacific (Sydney) · ap-southeast-2 | Sydney, NSW |
| AWS | Asia Pacific (Melbourne) · ap-southeast-4 | Melbourne, VIC — opened January 2023, three availability zones |
Oracle Cloud and Google Cloud also operate Australian regions, so keeping data onshore isn’t limited to one vendor.
Why the location matters#
Privacy obligations
Under the Privacy Act, Australian Privacy Principle 8 covers disclosing personal information to someone overseas, and generally makes your business accountable for how that recipient handles it. Whether overseas cloud storage counts as a disclosure depends on how much control you keep — which is exactly why keeping personal information in an Australian region is the simpler position to be in.
Speed for your team
Data that travels to the other side of the world adds delay. For file access, line-of-business apps and remote desktops, a nearby region usually feels noticeably faster.
Resilience
Location is also about recovery. Running systems in one region and keeping backups in another — Sydney and Melbourne, for example — means a regional outage doesn’t take your data with it.
A short pre-migration checklist#
- 01List the systems you plan to move and the kind of data each one holds.
- 02Flag anything containing personal, health or financial information.
- 03Choose a primary region — and a second one for backups.
- 04Confirm every service you need is available in those regions.
- 05Decide who can access what, and switch on multi-factor authentication before anything moves.
- 06Test a restore from backup before you switch over, not after.
Getting these right up front is most of what makes a migration uneventful. It’s how we plan cloud migrations across Azure, AWS and Oracle Cloud — one environment, managed as a whole.
Common questions
Can my business keep its cloud data in Australia?
Yes. Microsoft Azure and AWS both operate regions in Sydney and Melbourne, and other major providers have Australian regions too. You choose the region when you create each service.
Does storing data in Australia make my business Privacy Act compliant?
Not on its own. It simplifies obligations around sending personal information overseas, but you still need to meet the Australian Privacy Principles for how information is collected, secured and used.
Should cloud backups be in the same region as my systems?
Ideally not. Keeping backups in a second region protects you if the primary region has an outage.
