Just to add to Sir Humphrey’s comments, this should be covered by strata insurance (if at all), so, if you are an owner, your claim should initially be against the owners corporation (body corporate) for the reasonable costs of alternative accommodation and ancillary costs (like removals expenses).
If you are a tenant, the claim should be made against your landlord who can then take up the matter with the owners corp.
If the OC or strata manager won’t come to the party and the issue is covered by their strata insurance, you may be able to take it up directly with the insurer.
