PERTH, Australia (AP) _ Eleven aborigines died today in Western Australia's worst road accident when a station wagon and sedan collided near Laverton in the state's remote interior, officials said.

Seven men and three women died immediately and one man died while being transported to Perth, about 430 miles away on Australia's west coast. Their ages were between 16 and 40.

Police said the two vehicles collided head-on on a gravel road just outside Laverton this morning. Two men survived and were flown to Kalgoorlie, nearly 200 miles away, where they were both in serious condition with multiple fractures and head injuries, the Royal Flying Doctor Service said.

One officer described the crash scene as ''horrific.''

Police said they did not know what caused the accident, and investigators from Perth were flying to the region.

The drivers and passengers were from Laverton, Leanora, Wiluna and the Central Reserve near Warburton, police said.

The state's previous worst road accident occurred in October 1982 when a bus plowed into a tree near Merredin, killing nine schoolchildren and the driver.
