A sports ball rebound and boundary system including at least one portable post portion, configured to in use stand upright unsupported, and a barrier portion. The post portion and the barrier portion are configured for mutual releasable connection so that at least part of the barrier portion is extendible from the post portion to form a substantially vertically aligned planar barrier extending upwards from substantially ground level. The barrier portion is further configured to in use remain under sufficient tension to cause a ball or similar to rebound when striking the barrier.
