Silt dredged from Sydney Harbour was used to carry out the process and numerous sea walls and dykes were constructed as part of the program.

Trustees were appointed on 26 July 1878 by Governor Robinson[2] to manage the new park and a competition was announced to design the new facility.

After numerous complaints regarding the management of the competition, the construction commenced and by 1882 opinion had turned favourably to the new ovals, greens, paths, lakes and other facilities offered in the park, named in honour of William Wentworth.

[3] Throughout the 1880s and 1890s, the park came to serve as a focus for community activities including concerts, celebrations, moving pictures and in particular the home of Glebe Dirty Reds and sport in general.

[4] The commencement of hostilities for World War I led to a downturn in patronage of the park's amenities although community functions, such as stretcher drills and polling were carried out here.

After the Glebe Dirty Reds were removed from the competition at the end of 1929,[5] Balmain Tigers continued to play some of their home matches at the ground.

The nearby University of Technology, Sydney and other educational facilities regularly held student examinations within two levels of the grandstand.

Tenants to the Wentworth Park complex include Janison Exam Management (formerly Language Testing Consultants (LTC)[12]), The New South Wales Greyhound Breeders, Owners and Trainers Association (NSW GBOTA),[13] Equilibrium Climatec Joint Venture, Kane Constructions and Traino Australia.

[15] The biggest event of the year at Wentworth Park is the TAB Million Dollar Chase with the winner of the race going home with $A1,000,000.

[16][17] On 17 February 2019, the Glebe Dirty Reds played in a pre-season trial game against the North Sydney Bears at Wentworth Park; and won, 24–12.

[18] In 2023, it was announced that Glebe would be returning to Wentworth Park on a permanent basis and would be using the ground for all home matches.

[19] Currently the ground is used by not only the Glebe Dirty Reds but also the Sydney Roosters for the Knock on Effect NSW Cup and Jersey Flegg matches.
