Castle Hill is an interesting place to visit in Australia. It is one of the suburbs of Sydney and is located 30 kilometres away from the Sydney post office. Although Castle Hill has already become commercialised today, it still maintains its historical sites as part of its rich history. Castle Hill was once occupied by the Bidjigal people, who are thought to be a part of the Dharuk clan. They inhabited most of the west portion of Sydney for several years until the capture of their leader. Today, there is a part of Castle Hill that is commemorated for the Bidjigal people. The area is commonly known by locals as the Bidjigal Reserve.

After the inhabitation of the Bidjigal people, the European settlement started. Governor Phillip needed to find a new colony for farming crops and settlement. He thought of the area of Castle Hill as a productive land, and so he soon began a government farm sometime in 1801. He called it the “Castle Hill” which name is officially used today as the name of the entire suburb.

During the reign of the Europeans in the region, several accounts of maltreatment are recorded in history. During a night in 1804, many convicts, who were imprisoned by Governor Philipp due to violent activities, rose up to war against the thriving government at that time. The rebellion later was known as the Castle Hill convict rebellion. The convicts were able to overpower their guards and proceeded to free the prisoners of nearby jails. Thinking victory was almost at their grasps, they marched confidently to Parramatta, where they were outnumbered by the English troops called the Red Coats. Around 20 convicts were killed in the first clash, with still a number who were able to escape. A second fight was initiated by the convicts at a later date which resulted in further bloodshed. The exact number of casualties is not recorded in history.

Due to the rise of rebellious acts in the entire region, martial law was later declared in the whole colony. It resulted in a panic in the country as a whole. It continued for several days in the hope of attaining peace. Several people of Castle Hill, mostly convicts, left the suburb to join with other militants in the Hawkesbury plains. The population of Castle Hill dropped to around five thousand which caused a panic to the administration.

Several years later, Castle Hill was rehabilitated into a beautiful market garden. Its flowers and plants supplied Sydney for many years until the rise of commercial establishments in the area. Castle Hill is now the administrative suburb of the local government of Hill Shire. Although much has changed today in the suburb of Castle Hill in NSW, it still boasts its past with the Orange Blossom Festival which is celebrated once a year.

Some historic sites in the suburb are also being preserved by the government. Many of which are open for public viewing which also became a tourist attraction. Commercial establishments are already everywhere around the vicinity. Speciality shops can be found in the business centre. Its residential area is also situated near the schools and churches. Castle Hill has drastically increased in population, from the near 5,000 residents after the historic rebellion.
