Service Level Agreement (SLA) Australia
A service-level agreement turns service promises into measurable contract obligations. It should say what is measured, how failure is established and what happens next—not simply promise “99.9% uptime”.

What is a service-level agreement?
A service-level agreement (SLA) records the standard a supplier must achieve when providing a service. It can sit within a master services agreement, a SaaS subscription or a separate schedule. Australian businesses use SLAs for managed IT, cloud hosting, support, telecommunications, freight and fulfilment.
A useful SLA connects the operational promise to a contractual remedy. An uptime percentage without a measurement method, exclusions or consequence leaves both parties arguing about what the promise meant.
SLA versus MSA versus statement of work
- MSA: the overarching legal terms, including payment, liability, IP, privacy, renewal and termination.
- Statement of work: the particular project, deliverables, milestones, acceptance tests and charges.
- SLA: ongoing performance standards, measurement, reporting and remedies.
Specify which document prevails if they conflict. See our MSA guide and statement of work guide. A support schedule should not silently override the negotiated liability or termination terms.
Measure uptime without hiding the assumptions
Define the service boundary: is the whole platform unavailable, a core function failing or a particular customer unable to connect? Agree the monitoring source, reporting period, time zone and treatment of partial outages. A supplier’s dashboard and a customer’s monitoring tool may record different results.
Illustrative calculation: for a 30-day month with all 43,200 minutes eligible for measurement, 99.9% availability permits 43.2 minutes of downtime. Planned maintenance and other exclusions change the denominator; they must be stated rather than buried in a policy.
Response time is not resolution time
A promise to acknowledge a ticket within an hour does not promise to restore the service within an hour. Separate acknowledgement, technical response, workaround and resolution targets. Define severity by business impact, support hours, who can raise a ticket and the escalation path. Avoid a priority category that only the supplier can assign without review.
Service credits, chronic failure and exit
State how credits are calculated, whether they apply automatically or require a claim, and whether the customer must submit evidence within a reasonable period. Check caps and exclusions against the commercial impact of failure. A credit against next month’s invoice is little help after a customer has terminated.
Decide whether credits are the sole contractual remedy for ordinary SLA failure, and distinguish serious breach, repeated failure, security incidents and non-excludable statutory rights. Include a chronic-failure threshold, termination process and data or service transition obligations. The credit clause and liability cap must be read together.
Exclusions and dependencies
Scheduled maintenance should have a defined window, notice and maximum duration. Customer-caused outages need a clear causal connection. An exclusion for every third-party failure may remove much of the value where the supplier chose the hosting or subcontracting provider. Allocate responsibility for internet connectivity, customer configurations, backup, disaster recovery and security incidents expressly.
Consumer law and unfair terms still apply
Some business customers qualify as consumers under the Australian Consumer Law. Section 64 prevents contracting out of applicable consumer guarantees; section 64A permits only particular limitations where its conditions are satisfied. A service-credit clause is not automatically a substitute for statutory remedies. Standard-form consumer and small-business contracts must also be assessed for unfair terms.
Read the ACCC consumer guarantees guidance, ACCC contracts guidance and ACL in Schedule 2 of the Competition and Consumer Act.
SaaS, IT and logistics examples
For SaaS, distinguish platform availability from support and data recovery. For an MSP, distinguish response targets from backup verification and incident response. For a logistics provider, define on-time delivery by the agreed collection and delivery events, stock accuracy and the handling of unsafe or impossible schedules. Contract targets must not encourage breaches of transport safety duties.
Get the SLA reviewed alongside the main contract
Send the MSA, SLA, order form and any linked policies together. Our software and SaaS lawyers and transport contract lawyers can scope fixed-fee drafting or review. Use the SaaS checklist to collect the documents first.
Frequently asked questions
Is an SLA legally binding?
It can be, when incorporated into an enforceable contract. Check acceptance, incorporated policies, document priority and the wording of the obligations; an informal target is not necessarily a contractual promise.
Does 99.9% uptime guarantee compensation for an outage?
No. Measurement periods, exclusions and remedy provisions decide the contractual outcome. Applicable consumer guarantees and other non-excludable rights must also be considered.
Can service credits be the only remedy?
The parties may agree a limited contractual remedy for defined failures, but cannot exclude applicable non-excludable rights. Serious or repeated failures, termination rights and unfair contract terms require separate consideration.
