Update: from 11.59pm on October 18, Melburnians will be allowed to travel up to 25 kilometres to meet friends and family outdoors. The Covid 5km Overlap Finder has not yet been updated to reflect this. In the meantime, we recommend using these two alternate tools to find your 25-kilometre radius.

Over the last couple of months, every Melburnian has become very, very familiar with everything that falls within a five-kilometre radius of their home. Fortunately, meeting up with friends, even ones who live across town, is possible if you can find a good (and hopefully scenic) place to meet halfway.

But finding the overlap – that thin, hopeful sliver of space that falls between your respective five-kilometre zones – can be tricky to figure out, especially given most map apps don’t have an easy-to-use as-the-crow-flies function.

The Covid 5km Overlap Finder does exactly what it says on the tin. Just plug your address and your mate’s into the site, and it’ll find you the space intersecting the two. Or, as I like to call it, “the Friendship Venn Diagram.”

Now that we’re taking our first tender steps back towards socialising (we’re even checking the weather again now that it’s actually relevant – two-person picnics are the new clubbing) this simple tool will really come in handy.

Maybe – and I’m pulling this example out of thin air – you live northside because you didn’t join your mates’ yo-pro exodus south of the river a few years ago, so you need to find a mutually convenient patch of grass for sinking beers. Or maybe your friend lent you a book and you forgot your board shorts at his place pre-lockdown, and now you need to arrange a hostage swap because you’ve finished the book and you’re hoping to swim this summer. (Again, another made-up example.) Well, now you’re sorted. Thanks, Covid 5km Overlap Finder, nice work.
