Reef systems on Western Australia's pristine Kimberley coast are bleaching for the first time, marine scientists say.

Kimberley Marine Research Station scientists say three specific biospheres on the Dampier Peninsula have been affected.

"This is part of a global event that has devastated the Great Barrier Reef and now it is our turn," the research station said in a statement with photographs on Facebook on Sunday.
