Australia Public Cloud Market: Digital Infrastructure, Enterprise Migration & the Future of Cloud-Native Innovation

According to IMARC Group, the Australia public cloud market reached USD 23.96 Billion in 2024. The market is projected to surge to USD 150.97 Billion by 2033, expanding at an exceptionally strong CAGR of 20.21% during 2025–2033.

This remarkable growth reflects Australia’s accelerated digital transformation across enterprises, government agencies, financial institutions and startups. As organisations modernise legacy systems, shift to cloud-native architectures and adopt AI and automation, the public cloud becomes the backbone of their innovation agenda.

The public cloud market encompasses infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), and software-as-a-service (SaaS), enabling improved scalability, flexibility, cost efficiency and security for businesses across all industries.

Why is the Australia Public Cloud Market Growing?

Massive Enterprise Migration to Cloud Infrastructure

Australian enterprises are aggressively moving away from on-premise data centers toward cloud-based environments. Organisations increasingly prefer scalable, subscription-based, resilient platforms that reduce operational costs and offer flexible resource allocation. Cloud migration is now seen as critical for improving IT agility, strengthening disaster recovery and enabling real-time data accessibility.

AI, Machine Learning & Data Workloads Driving Cloud Utilisation

AI and advanced analytics require immense computational power and storage capacity. Public cloud providers offer accelerated computing, GPU clusters, AI model deployment tools and data-lake solutions — making cloud environments ideal for innovation. As businesses adopt AI-driven decision-making, automation and predictive analytics, public cloud demand continues to rise exponentially.

Digital Transformation Initiatives Across All Sectors

The shift toward digital-first operations — in financial services, healthcare, logistics, education and retail — is a major catalyst. From omnichannel retail to telemedicine to digital banking, industries rely on cloud platforms to deliver seamless, secure and scalable digital experiences. Cloud computing enables businesses to modernise their applications and support remote or hybrid workforce models.

Government Support & Cloud Adoption Policies

Australian state and federal governments actively encourage cloud adoption through digital infrastructure investments and cybersecurity frameworks. Public-sector agencies increasingly adopt secure cloud platforms to improve service delivery, data transparency and interoperability. This government-led transition strengthens national demand for public cloud services.

Growth of SaaS Platforms & Developer Ecosystems

SaaS solutions dominate business operations, including CRM, HR tools, ERP systems, project management software, cybersecurity solutions, and collaboration tools. Meanwhile, developers increasingly rely on PaaS offerings to build cloud-native applications using microservices, DevOps pipelines, containers and serverless computing.
