Short answer: Most Australian small businesses spend A$20,000–A$60,000 in one-off migration services for a straightforward lift-and-shift to AWS or Azure. Mid-market organisations moving 20–50 applications typically spend A$80,000–A$250,000, and regulated or refactoring-heavy enterprise programs commonly run A$300,000 to A$1M+. Ongoing cloud infrastructure is billed separately: roughly A$1,000–A$5,000 a month for small businesses and A$3,000–A$25,000 a month for the mid-market.
Typical cloud migration cost ranges in Australia (2026)
These ranges combine published 2026 benchmarks from Australian providers and IDC research. They cover the migration project; monthly cloud spend is shown separately.
| Organisation profile | Typical scope | One-off migration services (AUD) | Monthly cloud infrastructure (AUD) | Typical timeline |
|---|---|---|---|---|
| Small business | 5–10 apps, mostly rehost | $20k – $60k | $1k – $5k | 2 – 4 months |
| Mid-market | 20–50 apps, rehost + replatform | $80k – $250k | $3k – $25k | 4 – 9 months |
| Enterprise | 100+ apps, refactoring critical systems | $300k – $1M+ | $15k – $80k+ | 9 – 18+ months |
| Government / regulated | Sovereign hosting, APRA CPS 234, Essential Eight / ASD Essentials | $500k – $700k+ | Varies | 12+ months |
Some sources put small-business ranges higher (IDC research commissioned by Microsoft quotes A$70,000–A$200,000 for 10–50 workloads). The difference is usually scope: how many workloads, how much remediation happens before cutover, and whether the security and compliance work is included.
What actually drives the price
- Number and complexity of workloads. Ten well-documented virtual machines cost far less than ten legacy applications with undocumented dependencies.
- Migration strategy. Rehosting (lift-and-shift) is the cheapest per workload. Replatforming and refactoring cost more up front but usually lower your monthly bill.
- Data volume and cutover window. Large databases that need near-zero downtime require continuous replication (CDC) and rehearsed cutovers.
- Compliance obligations. APRA-regulated firms, government suppliers and critical infrastructure operators need more design review, evidence and sign-off.
- Identity and networking redesign. Moving to a proper landing zone with least-privilege IAM is the right decision, but it adds scope.
The 7 Rs: choosing a strategy per application
Good migrations don't treat every system the same way. Each workload gets one of the industry-standard “7 Rs”:
| Strategy | What it means | Cost profile |
|---|---|---|
| Rehost | Move as-is to cloud VMs | Lowest project cost, higher run cost |
| Replatform | Small changes, e.g. move to a managed database | Moderate; quick savings |
| Refactor | Re-architect for containers or serverless | Highest project cost, lowest long-term cost |
| Repurchase | Replace with SaaS | Licence-driven |
| Retire | Switch off what nobody uses | Saves money immediately |
| Retain | Keep on-premises for now | No migration cost |
| Relocate | Move a virtualised estate (e.g. VMware) wholesale | Fast, minimal change |
Hidden costs most quotes leave out
When you compare proposals, check whether these are included. They're the items that most often blow out a board-approved budget:
- Dual running. Paying for on-premises or hosted infrastructure while the cloud environment is proven in production.
- Licence overlap for databases, operating systems and security tooling during the transition.
- Internal staff time for testing, approvals and change management.
- Security and compliance artefacts: architecture decision records, threat models, evidence packs.
- Over-provisioning. New environments are almost always oversized at first because teams are cautious about performance.
How to bring the cost down
- Retire before you migrate. Most estates have applications nobody uses, and every one you retire is a migration you don't pay for.
- Automate with infrastructure-as-code. Terraform landing zones make environments repeatable, so later waves get cheaper.
- Run FinOps reviews at 30, 60 and 90 days. Right-size compute, buy savings plans for steady workloads and remove idle resources. Benchmarks suggest total cost of ownership often falls 20–30% in the first year once these practices are in place.
- Blend onshore and offshore delivery. An Australian lead architect with an engineering pod in India typically costs 40–60% less than an all-Sydney team for the execution-heavy phases. See our staff augmentation rates guide.
How Kodeclust quotes a migration
We start with a fixed-price discovery that maps your workloads, dependencies and compliance obligations, then quote the migration as fixed-price milestones rather than open-ended hourly billing. Every proposal itemises dual-running, licence overlap and post-migration FinOps so there are no surprises. Read more about our cloud migration and DevOps services.
