Proprietary sales volume data, page-2

Your margin numbers are higher than I would expect, they announced in the last quarterly that the overall margin went up from 51% to 54%.

In the MD presentation for FY16 they refer to "total sales volume 1.4 carton equivalents" and "proprietary craft products sales volume 0.35 million carton equivalents"

So you could convert carton equivalents to litres, to see what 0.35 million carton equivalents is in litres, and then scale up the percentage announced in the last quarterly. ASSUMING they released an apple to apple comparison percentage in the last quarterly.

Best data I found has been in the annual reports/presentations. The quarterlies are just a quick update.
