‘The Voice Australia’ witnessed a unique audition when 19-year-old Jordan Fuller sang, followed immediately by his 16-year-old sister Sian. Jordan had planned to audition, but Sian was just there to watch. Sonia asks the producers, ‘Can we see whether or not Sian can audition today?’ Sian quickly replies, ‘I don’t know what I’d sing!’ Sonia tries to calm her down, telling her that she will go right after Jordan’s performance. #TheVoice #singer
