DPI NSW has released a report covering the departments' performance, data and insights for 2018. Amazingly, the data shows that hunting is fourth largest primary industry activity (in terms of output) for the state, coming in behind Beef Cattle, Horticulture, and Recreational and Charter Fishing.
The NSW DPI Performance, Data & Insights 2018 report shows the estimated economic contribution from regulated hunting activities and related expenditure is in excess of $1.8 billion. With a figure of $1.54 billion estimated in 2017-18, there has been clear growth of hunting in NSW.
