Two animal shaped crafts fly over the beach in Queensland on an westerly breeze

The craft was shaped like an animal, as it had are large mass, and four descending columns from each side.  There were two of them, one in front of they other.  They appeared over us as my freinds and I were swimming in the morning.   Everybdy else was still in bed, but us 14 were there, watching them as they came from the east, went over the beach, and then travelled out across the country.  No one else has seen it since, but I think I found something on the internet with a discription a lot like what we fround.
