As an application, we extend the notion of Rokhlin property for $G$-C*-algebra, introduced by Barlak, Szab\\'{o}, and Voigt in the case when $G$ is second countable and coexact, to an arbitrary compact quantum group $G$. All the the preservations and rigidity results for Rokhlin actions of second countable coexact compact quantum groups obtained by Barlak, Szab\\'{o}, and Voigt are shown to hold in this general context.
