I live close to it and work even closer to it.
On the day just before it hit hard, people were being evacuated from Brisbane city. I work in wooloongabba which is near it, so I was somewhat fine. I would look out the window in my cubicle and for about 4-5 hours, it was a constant grid lock.
This was followed by stories of supermarkets all over the place being cleared out of bread and toilet paper amongst other things. I live on the Gold Coast, which is a way away from Brisbane city (but I work in Brisbane city) and even here Bread is really scarce and over-priced right now. A lot of essentials like rice even are being cleaned out.
Anyway, the eeriest part of that day was leaving work at about 4:30pm. Brisbane was like a ghost town.
Imagine rush hour in any city being replaced with nothing. Nobody around. Nobody on busses, or at the busway. At a time of day when it's usually bustling with people trying to get home, all at the same time.
All that day too, I was monitoring the status of the train lines, and one by one they were being cut off completely. Scary stuff.
The next day I tried to get to work, but the train line I take was cut too. I ended up spending the rest of the week with my girlfriend.
But yeah, scary stuff. Plenty of footage of cars being tossed around like skittles. The photos of Brisbane city amaze me to no end. Seeing the places I frequent all the time submerged. You'd not think it were possible in a city. But I suppose south east Queensland is a flood plain.
