Here is an investment that worked out...

"A 30-SECOND phone call left Darwin Sportsbet the only losing betting outlet after Geelong's record-breaking Grand Final win.
A regular client rang three hours before the bounce of the ball and bet a staggering $340,000 at $3.50 on the Cats to win by 40 points or more. He won $850,000.
"It's by far the biggest bet we've ever taken," Darwin Sportsbet's Phil Hannah said. "We were out of our misery pretty early. It was a horror result." "
