Explosion

Did anyone hear an explosion this evening (Boxing Day 2019) in or around Perry Vale? My wife and I both heard it quite clearly and wondered if anyone had any clue what it was. Didn’t sound like fireworks (or a gunshot) or somebody dropping something loudly. Must’ve been around 10pm.

If anyone else heard this, I’m an easily-paranoid/now-quite-worried Perry Vale homeowner who’s out of town for Christmas… Any more news on this?

I heard this too but no idea what it was?

Potentially similar to this?

Did it sound like a large thud? Possibly a sonic boom. This article is from a few weeks ago:

Yes it was very loud but no plane sounds
