Internet Service Providers in Australia Industry Data and Analysis
The Internet Service Providers industry has suffered from declining revenue over the past few years despite consumers' increased reliance on the internet. Market share concentration is declining as intense competition from small-scale providers offering attractive packages has driven demand away from the major incumbents like Telstra. This price competition has forced major players to push down their prices, eroding profit margins and overall industrywide revenue. Cost-of-living pressures have led consumers to opt for lower-cost, lower-speed internet plans, although demand for high-speed services persists among tech-savvy households and businesses. With the NBN rollout now saturated and mobile, wireless and satellite technologies providing strong alternatives, traditional ISPs face greater challenges in acquiring new customers and sustaining revenue. Nonetheless, growing data consumption for cloud computing, streaming and remote work continues to support investment in faster, more reliable infrastructure, although providers must compete aggressively on both price and service quality to retain and expand their customer base. Overall, revenue is projected to contract at an annualised 4.5% to $6.5 billion through the end of 2024-25. Revenue is expected to sink 2.2% in 2024-25.
