Barrett, who found out he had won the TV while painting a supermarket roof, was so uninvolved in his competition entry he did not initially realise how flash his new TV was.
A quick text to his girlfriend revealed the extent of his good fortune.
"She was a bit jealous when I won, but she's happy now."
He was tempted to sell the TV but had instead decided to enjoy it for a while - perhaps indefinitely.
For now, his old $600 TV has been relegated to the bedroom.
"The new TV's amazing. The picture quality is almost scary in how good it is. I'm enjoying the features on it, it would be hard to go back."
