"I am more sure than ever this show is 100% rigged. I won't be back next year. Don't care who wins. I'm out."
In a statement given to the Daily Mail while the show was still live, a Channel Nine representative revealed the problem was not widespread and occurred due to a high number of votes.
"We have had an overwhelming number of votes throughout the week. Hundreds of thousands of votes have been coming through during tonight's show which has caused some technical problems for a small number of viewers, however, votes are continuing to flow through," the statement read. "The technical problem has now been solved. We appreciate everybody's support for the artists and the show. Voting is still open."
Diana— who beat Melbourne busker Daniel Shaw— was lost for words when she was announced as this year's winner.
"I'm overwhelmed. I'm overwhelmed. I am dribbling everywhere. I am honoured. Thank you Australia," the 35-year-old said in her emotional acceptance speech.
