The Turkish Government is to ban all members of the state parliament in New South Wales from attending the centenary commemorations at Gallipoli in 2015.
The move was a response to motions the NSW parliament passed in May, officially recognising the Armenian genocide.
The ABC reports an estimated 1.5 million Armenians died in Ottoman Turk-controlled territory between 1915 - 1922, but the Turks have long denied that genocide occurred.
Turkish officials described as outrageous the motions passed by both houses of the New South Wales parliament, that condemn the genocide.
The Foreign Ministry said the proponents of the motions will no longer be welcome at the Gallipoli commemorations and the council at Gallipoli has backed that.
AAP reports Turkish consul-general Gulseren Celik was asked on ABC Television whether the statement meant that Premier Barry O'Farrell and other NSW MPs would be denied visas to attend the Gallipoli service.
"Yes," she said.
