Castle Hill Touch was established in 1986. The local competition was played on fields behind Castle Hill RSL,

During its peak, the park competition had as many as 40 senior teams, and 2 representative teams.

In 2001 the RSL Club playing fields became unavailable when the RSL club building was extended.

From 2001 – 2005 the club struggled to find a permanent home with the competition moving between a number of playing facilities including Fred Caterson, Bella Vista, Castle Hill Showground, Eric Mobbs and Greenup Park before re-locating to Bernie Mullane Sports complex in 2005.

In this period the local competition was run by the YMCA before handing over control to Belgravia Leisure in 2007 whilst still at Bernie Mullane Complex. In 2008 the club was once again on the move to Green Up Park Castle Hill.  By this time the local park competition featured only 7 teams and was in danger of folding.

At this point Brad Mitchell took over as president and formed a new committee. The club was rebranded as Hills Hornets Touch, and a new strategic plan was agreed.

Since that time Hills Hornets Touch has grown to now boast 150 teams including 115 junior teams. Numerous representative teams are entered into NSW Touch competitions.

The success of Hills Hornets has been recognised by NSW Touch, where it has been awarded the Affiliate of the year in 2014, 2015 and 2017 at the annual NSW touch awards. President Brad Mitchell has been Awarded NSW Touch Administrator of the year for 2014, 2015, 2016 and 2017.
