AmbVic finally replied to my email and provided a spreadsheet of the branch locations, this time unencrypted. They actually included more info than I asked for which is nice, and also how I learnt that there’s such a thing as seasonal ambulance branches and also “super response centres”.

For anybody who was curious, there’s 260 entries in the list, although that includes the season stations, air ambulance locations, “community” branches (which I assume means volunteer), and the mobile stroke unit base
