In this compilation over 20 islands are identified as being connected at some times and in some ways with the incarceration control of convictsdetaineespeopleprisonersetc. To give order to this work the prison islands have been divided into three groups original transitional and situational. Note these groups are not clearly discrete chronologically there is overlap. Also note that although transportation to Australia ended in 1868 original places of imprisonment where convicts were kept not all were on islands remained gaols. Inmates were not released. Their imprisonment continued. For some it continued using that infamous phrase associated with the convict era for the term of their natural lives. Their torture went on and on until they dropped then their abused bodies were dumped into crude graves. The second group identified as transitional covers the islands where prisons were established after original places of incarceration were closed or were set up to imprison Indigenes who the genocidal White invaders were intent on killing with poisons like arsenic and strychnine with bullets and the deaddrop noose. Prison islands identified as situational were established to keep people deemed undesirable from remaining on or reaching the mainland. All were established in the 20th century. The descriptor situational is used as any or even all could again become incarceral places depending on contemporary political circumstances.
