Chris Dawson has faced Central Local Court today, as determinations got underway regarding his eligibility for bail.
Wearing a black shirt and what appeared to be a grey/green cardigan, Mr Dawson sat hunched with his head in his hands for most of the proceedings, otherwise cupping his chin with his knuckles or gripping his face.
He also appeared emotional, reacting at times as his role as a father and husband were discussed in court.
Mr Dawson interjected during proceedings twice as the prosecution argued its case regarding bail, at first saying "that's a joke" as Lyn's disappearance was discussed.
Shortly after, he exclaimed "you're kidding!" when it was raised that due to his likeness to his twin brother Paul, granting bail could possibly result in Chris using this to his advantage - even if he surrendered his own passport.
At this point, the presiding judge asked Mr Dawson to be quiet, to which Mr Dawson replied "Sorry, your honour, I didn't know you could hear me".
Greg Walsh, Mr Dawson's lawyer, said that his client is willing to offer up $1.5 million in surety towards bail, and would also be willing to enter an agreement for further conditions.
Aside from a full media area in court, there were members of police in attendance at the proceedings, including Detective Senior Constable Damien Poole, who has played a large part in the investigation.
His bail application will be determined on Monday, December 17 at 2pm.
