Festival crowd flocks to Hicks' book signing

David Hicks received a standing ovation at his first public appearance, at the Sydney Writers Festival today.

Hicks is the Australian who was branded a terrorist by the US Government and spent five and a half years in Guantanamo Bay, after he was captured in Afghanistan in 2001, and sold to the Americans.

Hicks was being interviewed by journalist Donna Mulhearn following the publication of his book Guantanamo : My Journey about his experiences as a freedom fighter and then enemy of the United States.

The audience of 900 were people of all ages, most of whom clapped during his talk and gave him a standing ovation at the end.

At times, the quietly-spoken Hicks found it difficult to recount some of his experiences of torture inside Guantanamo.

During the interview, Hicks repeated his assertion that not only was he not fighting for al-Qaeda but had not even heard of the terrorist group until his American interrogators mentioned the name.

Hicks, who grew up in Adelaide and was a high school drop-out, said he had converted to Islam to gain a sense of belonging. He travelled to Kosovo and Kashmir to help suffering civilians after he had worked in Japan as a horse trainer.

Mr Hicks was convicted by a US military commission on charges of providing material support for terrorism but has faced no charges in Australia.

The US Military Commissions Act of 2006, ''which is the one I was forced to plead guilty under'', had since been scrapped by US President Barack Obama, Mr Hicks told the festival.

''Because of that my US lawyers say that my conviction is now null and void,'' he said.

Mr Hick said he never hurt anyone, and never planned to hurt anyone during his time in Kosovo and Pakistan and Kashmir.

''I went overseas with the intention to help people. Some people may think it's a bit weird, a bit strange, impulsive, naive - OK. But my intentions were good. And unfortunately I ended up being detained and tortured and accused of being a terrorist.'' A long queue formed as Mr Hicks signed copies of his book, under the gaze of the ABC's Australian Story cameras, but he refused to answer media questions.
