I noticed this on a Garuda Flight from DPS to SYD.

I was seated in row 2 and knew exactly where we were, over Botany Bay on very final approach.

The cabin crew were still gossiping in the galley, trolleys were still unlatched and out, I was starting to move away from aisle as I could imagine carts flying down the aisle as the breaks were applied, when a FA rushed forward and goes - we are about to land.

A mad scurry and everything was secured, the crew were stapping into jump seats as we hit the runway.

There was no announcement - re preparing the cabin for landing or cabin crew take your seats for landing.
