It's hard to imagine how the keep the sheep campaign will make any difference in urban seats. People tend to vote in their own interest first, myself included. Live sheep exports would surely be a long way down the list of concerns for urbanites.
I also find their campaign a bit on the nose. Why should I or any other average millennial vote to keep live sheep exports for the profit of farmers? Farmers reliably vote for liberals / nationals who have gone out of their way to fuck over anyone not born in to wealth since at least the Howard era. Why would they think we would vote against our interest for them when they didn't do the same for us?
I used to work for a company that agreed with you, well at least some clown in management did. Even though it was an Australian company, at least part of the problem was we had an office in Manila, and they speak "American English" which seemed to include the awful date system too. We dealt with a lot of files being issued to clients / received from vendors etc. Because the "official" system used those fucked up dates, everyone ran their own secondary sets of data folders in / out with everything done in ISO dates so you could actually sort it properly.
