LOCATION:Whiteman Park, Western Australia.

WITNESSES: Four witnesses.

OTHER DETAILS: A family of four watched this object for several minutes, from a lookout point in Whiteman Park.

"It "moved about like a plastic bag", while the family argued about what it was. The whole family went back to the car, apparently unimpressed, but the mother came back with the camera, and as soon as she started filming the object moved away. (I've interview this witness over the phone, and find her to be extremely credible.)
