Last night plumbing that services my apartment and my three neighbour's (either side and above) got blocked by tree root damage (assessed by plumber) and water gushed out of my bathroom drain and over the course of several hours, flooded my apartment. I was the only apartment to bear the brunt. Body Corporate has taken responsibility for calling out a plumber (granted it was 8 hours after the start of the blockage) and he has stopped the flood but my carpets are soaked and BC is baulking at indemnifying me. They are saying it's my responsibility and I should claim under my house and contents insurance, which I don't have.
What are my options here and who is right and why?
Now I am even colder in Canberra.
Awful situation to be in OP, sorry to hear.
Typically, Body Corporate should insure the overall structure and common areas, while unit owners are responsible for their internal premises. I would request a copy of the Body Corporate's insurance, as you're entitled to as a unit owner, and immediately seek legal council.
I don't expect that you'll be able to claim under the Body Corporate's insurance, but by all means, do your due diligence. You'll never know if you don't investigate.
Unfortunately, as you have no insurance, any claim you have will require for you to go up against the insurance company of the Body Corporate which will be an uphill battle from the get go.
