Federal police are wasting their time on a "futile" investigation into allegations Australian activists were sexually assaulted by Israeli authorities while delivering aid to Gaza, the country's ambassador says.
Eleven Australians took part in the Global Sumud Flotilla to Gaza in May when they were detained in international waters at gunpoint, before being imprisoned and eventually deported from Israel.
Members of the group allege they experienced violence, sexual assault and abuse while in the custody of the Israelis.
Australian Federal Police have begun inquiries into the allegations.
But Israel's ambassador to Australia Hillel Newman said he had not seen any request from federal police.
"They're wasting their time on such a futile accusation of such kind," he told ABC radio on Wednesday.
