Melbourne beaches safe for swimming

Melbourne beachgoers have been given the green light to once again take a plunge in the bay after wild storms sent bateria levels through the roof.

Melburnians have been given the all-clear to again swim at the city's beaches after the bay was last week contaminated by faecal matter.

Environment Protection Authority Victoria on Tuesday said conditions had improved at the city's beaches overnight after a torrential downpour last Thursday sent large amounts of faecal pollution washing into Port Phillip Bay.

All 36 bay beaches are suitable for swimming and are rated as either good or fair, EPA spokesman Dr Anthony Boxshall told AAP, but people should still avoid swimming in discoloured water or near stormwater drains.
