If you've ever wanted to dive at Western Australia's World Heritage-listed Ningaloo Reef, now may be the best time to do so.
Mass coral spawning has drawn large numbers of huge plankton-feeding whale sharks to the Gascoyne Coast, making it a dream destination for photographers and tourists.
Australia's Environment Minister, Bill Marmion, said increased nutrients in the water from the coral spawn had triggered an increase in activity of planktonic feeders.
"Ningaloo Reef is one of only a few places in the world where whale sharks regularly appear close to shore, where they are easily accessible to observers," he said.
Marmion said up to 150 species of coral will reproduce during the coral spawning period.
