Hi Jocko
From a fire integrity perspective;
The aforementioned resident is in breach of, AS 1905.1 Components for the protection of openings in fire-resistant walls – Fire resistant doorsets, and possibly the Environmental planning and Assessment Act 1979.
From a strata perspective;
He is making illegal changes to common property, and is in breach of the relevant sections of the strata schemes management act and any by-laws you may have about changes to common property or tampering with fire fighting devices.
So to answer your question, yes, recourse is through the appropriate STRATA channels. The fire brigade only deals with fighting fires.
Consult your strata or building manager for an applicable escalation process.
With kind regards
