The length of a corroboree could vary dramatically, from a single evening to a marathon of ceremonies lasting weeks. Accounts from observers like Trollope, and Lady Barker describe performances that lasted within a single night.
However, John Morgan wrote of a great corroboree that lasted “about three hours.” He also mentioned a corroboree that was performed “evening after evening for about six or eight evenings successively” and “a grand corroboree, which lasted about three day.”
For major sacred events, the duration was extensive. Spencer and Gillen documented that an “important” corroboree could occupy “ten days or a fortnight.” The Engwura ceremony they described lasted for several months. R.N. Richard Sadleir also mentioned a ceremony on the Macleay River that occupied “a fortnight or more.”
