The jury was sent home just before 1pm on Friday, with Supreme Court Justice Michael Croucher reminding them not to discuss the case with anyone over the weekend.
They will return to their deliberations at 10am on Monday.

The 57-year-old has pleaded not guilty, claiming the two deaths were accidental, but admitted burning the crime scene and the "despicable" act of moving and destroying their bodies.
Lynn told the jury, and police during his interview, that Mrs Clay died during his struggle with Mr Hill over Lynn's gun, when a shot discharged and went into her head.
The accused murderer said Mr Hill died in a second struggle with a knife.
Jurors officially began deliberating on Monday.
They returned to court with a question on Wednesday, asking to re-watch the evidence from Lynn and police ballistics expert Senior Constable Paul Griffiths.
Justice Croucher allowed them access to videos of the live stream, which he said were each about two-and-a-half hours long.
Before deliberations began, he directed the jury to more readily reject prosecution theories that were not cross-examined, and more readily accept the evidence from Lynn and Sen Const Griffiths.
The judge reminded the jury on Friday that they could ask further questions by passing a note to his associate.
He also reiterated that they needed to apply his directions of law during their deliberations, before allowing them to leave for the day.
