Kinka Reserve is a large Crown Reserve under Northern Beaches Council’s care and control. The reserve is approximately 2.9 hectares of which approximately 2 hectares contains high quality remnant endangered Duffys Forest Ecological Community (Threatened Species Conservation Act 1995). The remaining 0.9 hectares was highly disturbed and in a poor state. Duffys Forest Residents Association (DFRA) aimed to make the 0.9 hectares into an arena for local horse riders to sustainably exercise their horses. This idea that was first thought of over a decade ago beforehand, but insufficent funding prevented it from progressing. Approval was finally granted and construction of an area started.
On the 11th March 2012, Kinka Reserve was offically opened by the Honourable Robert Stokes MP.
