In the City there are many many alternatives to go & find your supplies, this is not usually true in the Country. If it's not at your local store then it's a fair drive to the next one.
As this also seeding time or very close to it farmers will have extra staff they have to feed to get the job done & this is already being made a lot more difficult to do with purchasing restrictions currently in place.
There is also a severe lack of Medical Infrastructure in many Country towns. Their relative isolation is one of the main tools they currently have in the fight against COVID19.
Yes it may offend you & some others but I do know of a few small Townships in Country WA that would prefer it that they didn't have a large influx of tourists at the moment. I'm guessing the situation in Victoria would be similar but I'm sure the ones that do want tourists over the coming period will holler out loudly.
