This was a defining season in the Club’s young history, indeed a magical season! Four major events occurred:

The Club changed its name from Nepean to the ‘Penrith District Cricket Club’;
Penrith Rugby Leagues Club became our Major Sponsor;
Penrith City Council agreed to an Annual Grant of $11,000 to allow the Club to improve and better maintain Howell Oval and Cook Park.
the First grade won the Minor Premiership, then went on to win the Premiership!

It was the first occasion that any sporting team from the Penrith District had won a metropolitan First Grade Premiership in any sport.
