On Monday, Geoffrey Charles Hunt told Coroner Simon Cooper that the first time he became aware he was a suspect in Ms Butterworth's death was in 2011.

The inquest on Tuesday has heard that Mr Hunt, 65, was interviewed about Ms Butterworth in 1976, 1990, 2000, 2011 and 2014.

Mr Hunt was convicted in 1976 for the brutal murder of car saleswoman Susan Knight.

Police have given evidence to the inquest that during that time Mr Hunt also admitted to the murder of Ms Butterworth.

The inquest heard that Mr Hunt agreed to go with police to the Knight murder scene shortly after being arrested.

Mr Hunt spent up to 10 hours with police discussing the murder of Ms Knight, but said he was not asked about Ms Butterworth at all during the interview.

He told the inquest he was put back into a cell, before an officer brought him out again and asked him one question about Ms Butterworth.

Mr Hunt said he told police he didn't know anything about Ms Butterworth, and then copped a ''bricking''.

Mr Cooper asked Mr Hunt what he meant by a ''bricking'', and he elaborated that it meant he was bashed up.

Mr Cooper reminded Mr Hunt that he had affirmed to tell the truth.

''He only asks you one question about Ms Butterworth, he gives you a belting and takes you back to the cell?'' Mr Cooper asked.

''I really don't know now, it was a long time ago,'' Mr Hunt replied.

Mr Hunt said the last time he saw his family was in 2004 at his father's funeral, and he also saw some returned serviceman who fought with his father at Kokoda.

Mr Cooper quizzed Mr Hunt as to what year his father enlisted to go to war, and pointed out that Kokoda was fought in 1942.

''Who are these military people he fought with on Kokoda when he wasn't there?'' Mr Cooper said.

''I don't know,'' Mr Hunt replied.

Mr Hunt stared at the wall during the duration of his evidence.

The inquest continues.
