I’d just like to ad that, as well as alerting council, you should look at your strata plan’s by-laws and see where breaches have occurred, hold an executive committee meeting and issue a Notice To Comply for each of the by-law breaches you can prove.
And you should alert the Fire Services to probable fire safety breaches.
In other words, firstly make sure you have proof then hit them with everything you’ve got.
You’ll find the offiicial Notice to Comply form HERE
