Airservices Australia has released its Australian Aviation Network Overview report for May 2025.
- In May 2025, the Australian aviation network recorded a 2% decline, in line with seasonal trend, from the previous month in terms of daily average flights while international traffic maintained 6% year-on-year growth. However, geopolitical and trade policy uncertainty continue to pose risks to both demand and supply in the aviation sector.
- Industry’s on-time performance has reached another three-year high of 82% in April. This progress has been further supported by Air Traffic Flow Management (ATFM) compliance measures at Perth Airport which has significantly reduced delays.
- Airport Collaborative Decision Making (A-CDM) went live at Brisbane Airport on 10 May, marking a significant milestone in enabling operational data sharing and aircraft departure optimisation. As a globally adopted system, this represents a major capability uplift in our region and is expected to deliver a range of operational benefits across the network. Early operator compliance to key A-CDM processes has surpassed the 80% European benchmark and continues to improve.Rollout at Perth, Sydney, and Melbourne airports will follow in the next five months.
- Following strong service performance during the April holiday period, airspace and tower service variations increased slightly in May but remain at one-third of 2024 levels. No ground delays were attributed to Airservices at the major airports. A Ground Delay Program (GDP) is a collaboratively-agreed industry plan to balance scheduled demand with available runway capacity. Ground delays in May reduced by over 60% compared to the same month last year. Brisbane has had no GDPs for two months, and national GDP compliance was at 86%. We remain focused on building resilience across the network and at key locations through a robust recruitment and training pipeline, and strengthening workforce deployment across major hub and regional locations to meet industry demand.
