Located southwest of Melbourne, this wetland covering more than 10,000 hectares is a true treasure for birdwatching. During my trip around Melbourne, I met several Australian birders who told me that the Western Treatment Plant is one of the best places (if not the best) for birdwatching in Victoria, and even in Australia. Also known locally as “Werribee”, it is in fact a wastewater treatment facility managed by Victoria’s water authority. The ponds are environmentally friendly lagoons, and this biological treatment method is internationally recognized.
