Breaking down in tears, the husband and father of the two Australians killed in the Sri Lanka Easter Sunday terror attacks has described the moment his life changed forever.

He said his family had attended the church in Negombo for an Easter service and that he had only gone outside the church for five minutes when the bomb went off.

“Suddenly, at the end of the church ceremony, there was a huge noise,” Sudesh Kolonne told SBS News at a private funeral for is family held at their home.
