A regular sight near the Blaydin Point Immigration Detention Centre in Darwin . On this occasion those visible are agronomist and NT Council for Civil Liberties founder, Rob Wesley-Smith,left, and Richard Davis , a former Channel 9 employee who narrowly avoided becoming one of the Balibo 5 on East Timor , Malcolm Rennie going in his place . Davis has been staging the weekly vigil for about three years . Wes says some staff coming away from the centre snarl , others smile and wave . In 1984 Wesley-Smith was fighting Big Brother over the conviction of the Chamberlains and the incarceration of Mrs Chamberlain. He called for a royal commission into the whole affair and said a lot of new evidence had accumulated since the Chamberlain trial .The Chamberlains were later exonerated , the death of their daughter attributed to dingo attack.
