Total n = 276 (weeks beginning 27 July 2015–5 October 2020, inclusive).
BPC = beer per capita consumption;
LALs: litres of pure alcohol.
Per capita is based on the Australian population aged 15+ years.
On‐premises: beer supplied from containers > 48 litres (e.g. kegs). Off‐premises: beer supplied from containers < 48 litres (e.g. cans, bottles).
Models adjusted for autocorrelation with lag length based on Cumby–Huizinga test: on‐premises BPC (lag 3, P‐value = 0.0003); off‐premises BPC (lag 1, P‐value = 0.0032).
