With full credits to fellow Bartons fan Richard, a new filming location has been confirmed! It's the fire station seen in the episode Position Vacant, completing all filming locations used in that episode!
And what's really cool is that Richard reached out to Fire Rescue Victoria, the fire brigade, and they told him a little bit about the fire station and sent him a pic of what the station looked like in 1960. That last bit is important, as that is the way the station looked in 1987 during filming too; it has since been completely rebuilt and expanded.
Do you have pictures of Fire Station 31 from 1987-ish? I'd love to put them up on the site. Let me know.
You can have a look at the station, old and new, on the Filming Locations page.
While adding the fire station to the page, I also gave it a little upgrade. All the maps have been redrawn and there's now a handy little menu that allows you to "jump" to any filming location (seeing that the page is now way too long to scroll through).
