Book tells story of Timorese asylum seekers' daring escape to Darwin

Jose da Costa was among 18 Timorese asylum seekers who fled Indonesia's brutal, decades-long occupation of the former Portuguese colony.

After arriving in Darwin by boat in 1995, Mr da Costa moved to Melbourne where he met author Vannessa Hearman, whose new book, The Good Sea, recounts his journey of resistance.

The book was launched at the Northern Territory Writers Festival yesterday.

It was 1976, one year after Indonesia's invasion of the Portuguese territory then known as East Timor.

Over the 24 years that followed, more than 100,000 Timorese would die in a deadly battle for control of the now-independent nation known since 2002 as Timor-Leste.

In the 1991 Dili Massacre alone, more than 250 Timorese protesters were killed in a confrontation with Indonesian soldiers, sparking further mass protests hundreds of kilometres away in Darwin.

Back across the Timor Sea, as the occupation continued into the 1980s, Mr da Costa's family spent the first three years of his life hiding in the bush before they were captured while trying to surrender to Indonesian troops.

After his family was banned from returning to their home town or growing crops, and even subjected to home detention, Mr da Costa joined a clandestine youth movement fighting for independence while being guided by older activists.

In 1995, Mr da Costa was part of a group that organised a boat to leave East Timor in search of political asylum so they could continue to push for independence in safety.

He wrote a note to tell his mother he was leaving but could not find anyone he trusted to give it to her.

So, without telling his family, he became one of 18 asylum seekers, including a six-month-old baby, who boarded a small fishing boat — the Tasi Diak, meaning "good sea" — and headed for Australia.

"It was the most frightening journey at that time," he said.

After six nights aboard the small boat, the group arrived in Darwin and the trip remains the only successful crossing between the two countries during the 24 years of Indonesian rule.

Their perilous journey has now been chronicled in a new book, The Good Sea, the culmination of 10 years of research by author
