Website maintenance in Australia is an ongoing cost, not a one-off, and it is priced as a monthly retainer scaled to how much the site matters to your business. For a professionally maintained site or web application, most Australian businesses spend between A$400 and A$6,500 per month, and the gap reflects whether you are keeping a marketing site healthy or running a web app real customers depend on.
The bands below are recurring monthly figures covering the work that keeps software from rotting: security patches, dependency upgrades, monitoring, performance, and a budget of hours for the small fixes and features that otherwise sit in an inbox. They are not a help desk; they are a senior engineer who knows your codebase, on call.
Figures are in Australian dollars per month with GST shown separately on each invoice. A retainer is also tax-deductible as an ongoing business expense for most Australian businesses, which often changes how the cost reads against a one-off project.
| Engagement | Range | What's included |
|---|---|---|
| Marketing site upkeep | A$400–A$1,200 / month | Keeping a content or marketing site secure, fast, and current: patches, backups, uptime monitoring, and a small allocation for content and copy changes. The right tier when the site matters but isn't running an application. |
| Active business site or small web app | A$1,200–A$3,500 / month | A site with integrations, forms feeding a pipeline, or light application logic, plus a real monthly budget for small features and fixes. The band most growing Australian businesses settle into once the site is a working channel. |
| Web application or business-critical product | A$3,500–A$6,500 / month | A response-time SLA, proactive monitoring and performance work, ongoing dependency and security hygiene, and meaningful feature capacity. For software your business or your customers genuinely depend on every day. |
Marketing site upkeep
A$400–A$1,200 / month
Keeping a content or marketing site secure, fast, and current: patches, backups, uptime monitoring, and a small allocation for content and copy changes. The right tier when the site matters but isn't running an application.
Active business site or small web app
A$1,200–A$3,500 / month
A site with integrations, forms feeding a pipeline, or light application logic, plus a real monthly budget for small features and fixes. The band most growing Australian businesses settle into once the site is a working channel.
Web application or business-critical product
A$3,500–A$6,500 / month
A response-time SLA, proactive monitoring and performance work, ongoing dependency and security hygiene, and meaningful feature capacity. For software your business or your customers genuinely depend on every day.
A static marketing site needs far less tending than a web app with auth, a database, and integrations that drift as third-party APIs change. The more moving parts, the more upkeep, and the higher the band.
A guaranteed same-business-day response to a production issue costs more than best-effort support, because it reserves senior capacity for you. Business-critical software justifies it; a brochure site usually does not.
Retainers that include hours for small features and improvements cost more than patch-only plans, but they stop your roadmap stalling. The size of that monthly allocation is a direct lever on the price.
Every external system your site talks to is a moving target — APIs change, credentials expire, and breaking updates ship without warning. Sites with many integrations carry more ongoing maintenance than self-contained ones.
Senior engineers on retainer, not on a ticket queue.
