If a shopper they took their time, including it seems a "coffee"..
I think there's a degree of conservatism with the times though. Looking at "Mildura man"'s journey back from Melbourne to Mildura. Contact tracing suggests stopping at Ravenswood at 12:45-13:30 and Wycheproof from 14:00-15:00. I am very familiar with this trip, the journey is about 1hr 45 mins. No way you could arrive at Ravenswood at 12:45 - even without stopping - and be in Wyche by 14:00.
