Federal inquiry into shipping noise reaches Costa Mar

The Federal Court's ongoing inquiry into the environmental impact of Oriente Moderno's container shipping routes has opened a second phase of evidence-gathering in Costa Mar, focusing on acoustic damage to reef ecosystems. The investigation, which began in response to a 2024 grounding incident and subsequent reef damage near Nueva Singapur, is now examining whether the high-volume traffic through shared maritime zones affects fish communication and breeding behaviour across the region.

The Costa Mar Reef Monitoring Network submitted acoustic recordings and fish-population surveys to the Court in early October. The data shows a correlation between shipping-lane activity and changes in reef-fish vocalisation patterns, particularly among parrotfish and damselfish species that rely on sound signals for territorial and reproductive behaviour. The Federal Court has scheduled testimony from network scientists for November.

The case has become a focal point in the broader debate over maritime commerce versus conservation. Oriente Moderno's shipping industry argues that the container routes are essential to the region's free-port economy and that alternative routes would be prohibitively costly. Costa Mar's tourism and conservation sectors contend that reef degradation poses a long-term threat to both regions' marine economies.

The Court's decision on remedies—whether to impose routing restrictions, speed limits, or noise-mitigation requirements—is not expected until early 2027.
