Robert Gilbert Coshott was made bankrupt on 7 November 2008: see Shipton Lodge Cobbitty Pty Ltd v Coshott (No.2)  FMCA 1552.
There are then 374 cases involving the name Coshott on Austlii, whether one and the same as Robert Gilbert I have not checked, but I assume most are; and a few before.
The last, concerning Robert Gilbert Coshott, is the decision of the Full Federal Court in Coshott v Parker  FCAFC 14.
The series of cases raise a range of legal issues, often taken on appeal, which could be the source of an interesting academic study, in whatever area of law, or other, might be thought relevant.
Ideas are welcome.
