  We show that the dynamic asymptotic dimension of a minimal free action of an
infinite virtually cyclic group on a compact Hausdorff space is always one.
This extends a well-known result of Guentner, Willett, and Yu for minimal free
actions of infinite cyclic groups. Furthermore, the minimality assumption can
be replaced by the marker property, and we prove the marker property for all
free actions of countable groups on finite dimensional compact Hausdorff
spaces, generalising a result of Szabo in the metrisable setting.
