Joshua William Hickson, 30, is on trial for manslaughter over the death of Gregory Elms, 44, at his home in Kewarra Beach in January 2011.
Hickson has pleaded not guilty.
Mr Elms' next-door neighbour, Andrew Cook, has told the jury he heard arguing and assumed it was Mr Elmes on the phone.
He said several days later he noticed the smell of something dead but thought it was a snake.
Mr Elms' friend, Christopher McArdle, told the court he went to check on him and found a sliding door ajar and the place a mess.
He said he knew something was wrong when he saw Mr Elms' motorcycle, which he loved, tipped over and then discovered his body in a bedroom.
An acquaintance of Hickson, Michael McKay, told the jury he heard Hickson and his co-accused discussing going around to a guy's house to slap him around a bit.
A few days later, while the men were at Mr McKay's home, he said he heard a conversation about the co-accused knocking the man out with a cricket bat and the man being kicked while unconscious before his house was ransacked.
Mr McKay was unable to say who had made the statements as he was trying to ignore the conversation.
The trial will resume this morning, with the jury hearing closing arguments today.
