The Crosbie Morrison Amphitheatre and adjoining lawn sit within the Australian National Botanic Gardens in Acton, with a terraced paved seating area overlooking a sloping lawn, sheoaks and ponds. The Gardens describe a powered site, public toilets nearby and limited vehicle access for event set-up by arrangement. Chairs, tables and catering may be organised through the garden café or independent suppliers as permitted. A historical Australian Government commercial-event application lists 980 for the combined amphitheatre and lawn, whereas the older amphitheatre page specifies 100 seats for the tiered area; seek current approval and exact hire footprint.
