Who owns the airspace over my terrace?

I have a question about Stratum Statements in the Strata Plan

There is a statement included in my strata plan reads “Courtyards where uncovered are limited in stratum to 3m above & 3m below the upper surface of the Level 1 floor”

Does this statement mean that the owners corporation is responsible for anything located within the above boundaries in a private courtyard (not common area)

Thanks
