A woman who was injured after being accidentally hit with a flying boomerang is seeking nearly $40,000 in damages from the man she claims threw it.
Karen Reid has spent $18,000 on dental work since the accident at Yanchep National Park on December 28 and expects the bill to double.
Ms Reid said the boomerang was being thrown by a family near the park's visitors' centre and it veered off course and hit her in the mouth.
Doctor and dentist reports show the Pearsall mother of three lost a tooth and sustained damage to several other teeth and her jaw, as well as whiplash.
Ms Reid has called on the State Government to ban the 10,000-year-old practice of boomerang throwing so that no one else would have to endure the painful trauma.
She said the impact of a boomerang should not be underestimated.
"The boomerang could have hit me in the eye, temple or even my throat and it could have ended up fatal," Ms Reid said. "Under local government and public property laws, a person can't practise golf, archery, pistol or rifle shooting but it seems if a boomerang is thrown a blind eye is turned."
She is suing Cesar Viray, of South Lake, who initially offered her $6000 in damages after telling her in writing that his 10-year-old son had thrown the boomerang. Mr Viray has withdrawn the offer and has vowed to fight the action.
He referred Ms Reid to a previous case which did not hold parents responsible for an accident perpetrated by their child.
In a letter to Ms Reid, who is representing herself in the Magistrate's Court, he told her that she could become the "laughing stock of the WA legal profession for barking up the wrong tree".
Mr Viray declined to comment.
Ms Reid's local MP, Paul Miles, backed her calls to ban boomerang throwing in public.
"Given that the boomerang was originally designed as a deadly hunting weapon, I am astonished that this would not fall under the same category as say throwing a knife or spear in public," he said.
But Police Minister Rob Johnson said he would not include boomerangs in the Controlled Weapons Act, saying individuals should be responsible for their own actions.
