It was also in exactly the same stage in 2008 when his coaching stint at the Broncos came to an end, at the hands of the Melbourne Storm, in a controversial semi-final. It would not be until 2015 that Bennett would win a finals match at Suncorp Stadium.
, this is the most recent time that the Wests Tigers has played a finals match.
