The annual drama report from Screen Australia contains the best statistics in the industry with no sense that the numbers themselves are shaped for an ideological approach. It is just good solid data, well laid out, with the bonus of a complete list of productions measured.
The report has a couple of disadvantages. First, as many researchers have argued over the years, the data is frustratingly general. In just one example, the average per hour cost of television drama continues to climb, but independent companies are not seeing this in their revenue. Screen Australia sees a lot of budgets and CVs, but of course that information is confidential. Etc.
