Australia's IT developer market spans Java-heavy banking systems, .NET enterprise applications at large corporations, React and TypeScript at product companies, and the full range of modern stacks at companies like Atlassian and Canva. This guide covers real-time job support for developers working across these technology stacks at Australian employers.
Java is the dominant backend language in Australian financial services. Common environments:
.NET has significant presence in Australian government, insurance, and enterprise IT:
React is the dominant frontend framework at Australian product companies. Modern Australian frontend environments:
Frequent Java development support scenarios at Australian employers:
Full-stack developers at Australian product companies (Xero, Atlassian, SEEK, REA Group) work across the entire application stack. Support covers: API design between React frontend and backend services, authentication with AWS Cognito or Auth0, state management with Redux Toolkit or Zustand, performance optimisation for React applications, GraphQL schema design and resolver implementation, and end-to-end testing with Cypress or Playwright for Australian employer CI/CD processes.
Frontend development at Australian banks is an increasingly significant area as digital banking transformation drives investment in customer-facing applications and internal tooling. Banking frontend environments use: React or Angular (NAB, CBA, Westpac and ANZ all have active frontend engineering), accessibility compliance (WCAG 2.1 AA is required for Australian government and expected in banking), performance optimisation for mobile users on Australian mobile networks, and integration with Australian payment and identity systems.
Spring Boot 3 is dominant for new development. Spring Cloud (Gateway, Config, Eureka) for microservices infrastructure. Many banks also have legacy Spring MVC and JPA applications being maintained and gradually modernised. Kafka integration is standard for event-driven banking systems. Understanding both modern Spring Boot 3 and legacy Spring patterns is valuable for Australian bank Java roles.
React is dominant at Australian product companies and startups (Atlassian, Canva, SEEK, REA Group, Xero all use React heavily). Angular is more common at traditional enterprises and some banking institutions. For most Australian product tech roles, React and TypeScript proficiency is the relevant skill.
.NET 8 LTS is the current standard for new development. Many Australian enterprises (particularly government and insurance) still maintain .NET Framework 4.x applications. .NET 6 and .NET 7 codebases are also in active maintenance. The migration from .NET Framework to modern .NET is an active program at many large Australian organisations.
Very important for government and banking roles. The Disability Discrimination Act and Australian Government Digital Service Standard require WCAG 2.1 AA compliance for Australian government digital services. Banks and large enterprises are increasingly expected to meet the same standard. Frontend developers in these environments need practical accessibility knowledge — semantic HTML, ARIA attributes, keyboard navigation, and screen reader testing.
Atlassian, Canva, Xero, SEEK, REA Group (realestate.com.au), and Afterpay/Block are the most highly regarded Australian tech employers for full-stack developers. They offer competitive salaries, strong engineering culture, and modern technology stacks. Commonwealth Bank and Westpac's technology divisions are the best banking options for full-stack roles at scale with significant investment in engineering.
