Two European tourists have been rescued from a flood-swollen creek in Western Australia after activating a personal locator beacon.

The beacon was activated by the pair at 10.50am (WST) on Tuesday, the Australian Maritime Safety Authority (AMSA) said.

Police travelled to the creek, about 70km southeast of Karratha, but could not drive through the water to rescue the pair, whose car was submerged.

A Karratha-based helicopter took the uninjured tourists to Roebourne.

AMSA urges people travelling in remote areas to carry satellite phones and a personal locator beacon in the case of an emergency.
