Indonesia is dispatching a research team to East Nusa Tenggara province to evaluate the environmental impact of the 2009 Montara oil spill. The spill, originating from an offshore oil platform operated by PTTEP Australasia, has long been a source of contention between Indonesia and Australia. Indonesian officials allege significant damage to marine ecosystems and local livelihoods, particularly impacting fisheries and coastal communities. The team will collect data on oil contamination levels in water, sediment, and marine organisms. This assessment aims to provide a comprehensive report to support potential legal action seeking compensation for the damages. The findings will be crucial in determining the extent of the ecological harm and formulating remediation efforts. Indonesia hopes the investigation will finally provide definitive proof of the spill's lasting consequences.
