In an unexpected display of military activity, China conducted live-fire naval exercises in international waters between Australia and New Zealand, which diverted several commercial flights.

The drills, involving three Chinese warships, were not pre-announced to Australian authorities, which caused concern and prompted diplomatic discussions.

On February 21, 2025, airlines operating between Australia and New Zealand received sudden broadcasts from the Chinese navy, indicating the commencement of live-fire exercises in the Tasman Sea, approximately 346 nautical miles off the Australian town of Eden.

This unexpected notification led carriers such as Qantas, Emirates, and Air New Zealand to adjust their flight paths promptly to ensure passenger safety.

An Emirates flight from Sydney to Christchurch was among those that altered its route in response to the Chinese military’s message.

Australian Defense Minister Richard Marles expressed unease over the lack of prior notification, highlighting that the information was relayed to authorities by commercial pilots rather than through official channels.

He noted that while China complied with international law by issuing an alert, the minimal notice was “disconcerting” and led to abrupt flight diversions.

Prime Minister Anthony Albanese reassured the public that there was no imminent risk to Australian or New Zealand assets, emphasizing that the exercises took place in international waters.

However, the incident has raised questions about the adequacy of communication protocols and the potential risks posed by unannounced military activities in busy airspaces.

In response to the situation, Foreign Minister Penny Wong engaged in discussions with her Chinese counterpart, Wang Yi, during a G20 meeting in Johannesburg.

The talks aimed to address the importance of “safe and professional military conduct” and to prevent similar incidents in the future.

This event underscores China’s expanding military reach and the strategic implications for the Indo-Pacific region.

The presence of Chinese warships conducting exercises so close to Australian and New Zealand waters is unusual and has prompted both nations to closely monitor the situation.

New Zealand’s Defense Minister Judith Collins acknowledged the significance of the Chinese navy’s capabilities in the southern region, emphasizing the need for vigilance and preparedness.

The incident also highlights the necessity for clear communication and established protocols to manage military exercises in international waters, ensuring they do not inadvertently jeopardize civilian air traffic or escalate regional tensions.
