In the US you'd have lost your garage door as well, since everyone here has sectional doors rather than that cool roll up door. So that's, uh, a plus?
Seriously, glad you didn't have a major project under there - nothing worse than having to go back and redo or do repairs on such painstaking work. Cars are pretty repairable/replaceable.
Most importantly glad everyone's safe.
Thanks Jimmy, that would have broken my heart if the Astro cab was damaged. I think the car may have a few small dint's and scratches but I'm not fussed, it needed body work done, now there's a bit more.
Tear that crap out and build some overhead storage.
I helped my parents do it. Their house sold instantly to someone that LOVED the garage.
+1.
I hate the drywall ceiling in my garage. There's a ton of storage above that goes to waste.
+2
I'm looking at the garage you have... it isn't finished anyway. That's some valuable storage space. I have strips of about 2ftx4ft pieces of plywood put in the rafters of all my buildings with a bit of open space in between to get up there with a ladder. I store all kinds of crap up in it and you really can't see it. I would take pics but it's currently 2am here and we are expecting 6 inches of snow tonight.... so I might not make it out there in the morning. 
Yeah, I'm giving this some thought. I mean I first posted this as just a "hey look what happened here" kind of thing but really something good/useful should come out of it. Like I said earlier I used to live in a place where the garage had no ceiling and the guy before me had set up some storage space, it was very useful. There is something to consider though, the typical garage roofing framework (around here) is not really designed to be load bearing beyond supporting the roof. I think house design in Australia is pretty 'light weight' in terms of structural integrity. I know in Europe and parts of the US structural standards are much higher due to the environment (snow etc). That all said, some storage for boxes of lightweight items that get dragged out once a year (bloody Christmas Tree!) is still not a bad idea.
That sucks dude--glad no one was hurt--any idea what caused it? rain leaking through maybe? Seems odd that it just decided to drop one night without something to 'tip' it over the edge..if its any consolation i bet it fell in sequence--sort of like coming unzippered from the rafters--if you were in there you likely would have noticed it before it crashed on you...maybe..
I think you're probably right, god I hope it was rain (i.e. qualifying as storm event and covered by insurance). I didn't mention that I noticed a slight sag just along one ceiling edge of an inch or so a few weeks ago. Nothing I would have thought was that serious - the night it happened we had a huge temperature swing from 44 degrees Celsius (111 degrees F) to around 22 degrees (71 F) in the evening before. The garage is the only room in the house not insulated. I read online that this makes them prone to suffer from humidity which can cause glues to fail and weaken fastening points (nails or screws). I'd say it unzipped from the rafters, but quite quickly, I heard just the tail end of it clearly which sounded like movement across the roof - thus the 'cats on the roof'.
From the pics I don't see any screw holes. If it was held up by construction adhesive that is the most likely culprit. I know that stuff is supposed to be permanent, but I can assure you it isn't. I've seen many tile ceilings fall that were put up with it and obviously they aren't holding up nearly as much weight.
There are nails or screws as well as glue points. I haven't had a chance to look closely yet. If I redo it, I'll definitely use screws and adhesive.
If it was actually a true plaster ceiling I am surprised it has lasted this long. I used to work in the field for our demolition company and you would be surprised at how much heavier a plaster ceiling is compared to a sheetrock ceiling. Most times too the plaster ceiling would have a thick metal mesh that the plaster would be applied to. It was treacherous getting them down. We would have to create a hole in one corner and poke our body in and start cutting hangers. Not fun. I don't know how many times I got huge gashes on my arms. You are very lucky that no one was in the garage while it fell.
Congratulations on your daughter also. That is awesome news. 
It's not a 'true' plaster ceiling just boring old Gyprock or what others call Sheetrock I think. Gyprock is a brand here in Aus, but the term Plasterboard is the generic term.
Thanks for the congrats

I mean you gotta remind yourself of things like that now and then especially when this sort of crap happens. She got into a writers course which includes screen play, journalism and novel writing. It's a very job specific degree with a high job placement success rate, so I'm pretty chuffed for her!
Can I admit I've just moved into a place with a lot of garage potential and I'm pushing OND to do it just so I can steal his ideas?
Okay, because I've just moved into a place with a lot of garage potential.

Ah ha, the clouds part to show the true sky! So Jim, did you really help out your parents who had a quick sale!

Actually, before we decided to sell this place I had contemplated putting in one of those drop down ladders and adding some storage space in the garage. Those ladders are horribly expensive though ,even the cheaper metal ones are more than I want to spend. I may look at covering an area of couple of square meters with pine siding, putting in a manhole with a ladder mount point (for an ordinary ladder I mean). You can totally rip this idea off if I do it. It would be no big deal to add in while I'm repairing the ceiling.
Glad that you and the fam (Including Astro
) are safe. Ceiling cave-ins suck. I've dealt with a few myself. Your case looks like it is just a case of shoddy workmanship.
I'm gonna add another + on the leaving it alone and adding drop down ceiling storage and a hatch ladder to make it look intentional and then it will feel more useful.
Yeah thanks man

I'll report back whatever happens. Fingers crossed for Friday when the insurance dude comes out to look at. It's a real pain in the ass, I keep going out to get a screwdriver or something, open the door and look out over the mess. I know it probably looks a lot worse than it really is.
Not a great start to 2014 when your garage ceiling completely collapses and comes crashing down on top of everything. My garage is also my workshop so, yeah. *SIGH* This happened over night last Saturday at around 2 in the morning. My wife and I awoke to a huge crashing sound. I was so sleepy and out of it I started muttering about "cat's on the roof" my wife was somehow convinced I was right and we both went back to sleep!!.
Much different than my reactions to bumps in the night. A few months ago, we went to sleep, and at about 2-3 am, heard a small crashing type sound. I had heard something earlier while falling asleep, but it was light, so I just thought it was normal creaking/settling sounds of the house. Our master is above the garage, but I called 911 and proceeded to go through the entire house, leaving the garage until last, just to be thorough.
Of course, the dispatcher tells you to hunker down and stay put, but I can't do that. Better to get a jump on the intruder than the other way around, in my opinion. The officer arrives after I've got all the living areas cleared. Basement and garage last. Did the basement first, then to the garage. I look around, inspecting around each car, nothing. Then for whatever reason, I look again, and out of the corner of my eye, see a large opossum underneath the back end of my car! What kind of creeped me out was my feet were about 1-2 feet away from that thing at one point.
Opened the garage door, and shooed it out. Found out the source of the sounds. The small sound early on was a razor scooter that tipped over on its handles, thus the soft noise. The louder noise was an aluminum bat that was knocked from its slightly elevated position.
God I hate waking up to those kinds of sounds. You just never know until you've found everything, and by that time you're awake and the adrenaline's pumped through your body completely waking you up. Eventually went back to sleep later, but it took awhile.
Funny what sounds will alarm you and which you choose to dismiss. I've done the same, some little noise and I'm sneaking around checking rooms. We have a lot of cats around here, they get up on the roof and whine and moan, fight each other and race across the roof, I must have been really out of it that night!
Well the ceiling MUST be replaced I've decided that, there's just no convincing way I can explain to a prospective buyer why the ceiling isn't there. In this instance there's no way the builder wouldn't have completed the house without it.
Potential buyer - "I notice you have no ceiling in the garage"
Me - "Yeah it just fell down one night"
Potential buyer - backs away slowly - "Oh I see, well thanks for letting us look at your home"
Crickets chirping......
You guys have got to me though (again) I'll ponder the storage thing further
