I think he’s out at the moment, so I just walked over and left it at his door. It’s a safe neighbourhood, so there’s not really any risk of porch pirates. I did take a photo and left feedback on the Auspost website though

I did also have a package coming today that was due at the same time, and after checking the tracking apparently meant to be delivered by the same bloke, but it hasn’t arrived yet and wasn’t at the neighbours door (I thought perhaps he mixed up the parcels), so now I’m wondering what the hell’s happened to it
