As long as a four-person table
I've never seen a native bee hive before, let alone one this big! At first I thought it was a piece of bark which blew off the eucalyptus tree in the backyard. I ignored it for several days, before taking a closer inspection. Had I been there on the day I noticed it fall from the tree, I wonder if I could've tasted Sugarbag? That is what it has been coined by Indigenous Australians, instead of 'honey'.
Millions of cells created by an army of stingless bees
The good news is, when I did see this wonderful sight several days after it had fallen, the native bees were back at the tree, the old hive had fallen from. So I assume a queen had survived, or they would have flown away. The acacias are in full bloom now, so they should be able to restock.
Even if I haven't seen as many European honey bees around, I'm happy to know there's still a stronghold of native bees in my backyard.
I did a little research on our native stingless bees, and found while they're harmless to humans, you wouldn't want to be an African Hive Beetle - because that's a whole other story.
