Two copies of this script exist, one original and one modified; the modifications allowed the production to take advantage of actual flooding at Echuca. One script is written by Jim Stapleton and one by C.F. Barnes. Certain aspects of the scripts, including the character notes, demonstrate that Stapleton's was the original script and Barnes's the modified version (and therefore the version that was ultimately produced).
The alterations to the script between Stapleton and Barnes's versions (see publication details for more information) include alterations to the character lists.
The character notes appended to Stapleton's script reads as follows (omitting the regular characters):
'COOPER: Late 20's. Clean cut, model prisoner. claim's framed. [sic]'EVANS: 45 - 50. Outdoor type, lawyer.
