“[W]e face the real prospect of losing important Test and BBL cricket matches from Queensland to interstate venues during the pre-Olympic displacement from the Gabba and hold a reasonable fear that a suitable solution to enable continuity of matches in Brisbane may not meet our needs or expectations,” they wrote.
