It is a bit ambiguous. In 2020 the Total Turnover was $3b. Revenue and other Income $372m.
What perentage of the 2020 Turnover and Revenue/Income was Thoroughbred Racing in 2020? The bar graph would seem to be the TOTAL income NOT Thoroughbred Racing.
Thinking about it a bit more. The graph must be Turnover for Thoroughbred Racing because it the 2020 figure is higher than the TOTAL TAB revenue for 2020!
