Please note that many people are under the misapprehension that there is no longer a requirement for minimum headroom in staircase construction. This is not correct although you could be forgiven for thinking that it was. Nowhere in the actual staircase section of the BCA is there any mention of headroom heights, but for some reason, someone decided to slot that particular regulation in with 'ceiling heights'. So there is a headroom limit and it is 2 meters from the nosing line.

We believe that most of the regulations pertaining to stairs and balustrading are reasonable and work to promote safer buildings. Regulations should reflect industry standards and a balance between safety and practicality.
