About 403,000 litres of oil has been spilled into the Timor Sea by the Thai oil company PTTEP rig on Aug. 21. Since then, the world's last great wildnernesses is being “massively contaminating”, conservationists say.

“Amid a fourth attempt to plug the 64-day-old leak at the Montara drilling rig, the slick – which has already spread over an area 10 times the size of London – continued to expand at the rate of 300 barrels of oil a day in an area of the Timor Sea famed for its marine reserves and coral,” Guardian informs Oct. 23.

The article reads, “Satellite images show a 25,000 square kilometre slick spreading across the surface of the ocean and spilling into Indonesian waters, threatening the marine reserves of Ashmore and Cartier reefs along the way.

‘Clearly, wildlife is dying and hundreds if not thousands of dolphins, seabirds and sea-snakes are being exposed to toxic oil,’ said Dr Gilly Llewellyn from WWF.”
