However, those undesirable traits do not prove he murdered his wife Novy, his barrister has told a Brisbane Supreme Court trial.

Novy Chardon last spoke to some of her friends on the night of February 6, 2013.

She and Chardon were in the middle of a divorce and she had instructed her lawyer to send him a letter that afternoon relating to their split.

Prosecutor Mark Green told the jury friends had tried to contact Mrs Chardon the next day but didn't get a response.

One of them, Frederika Wong, went to the Chardon family home in Upper Coomera when Mrs Chardon didn't answer her calls.

She noticed the carpet in Mrs Chardon's bedroom was wet underfoot and a runner was missing.

Chardon told her he had cleaned it that morning with a hired machine, Mr Green said.

He then propositioned Ms Wong.

The businessman told another one of her friends Mrs Chardon wanted half of everything, and had lied to her lawyer about what she was entitled to in their property settlement.

The woman reported Mrs Chardon missing the next day. Her body has never been found.

Chardon has pleaded not guilty to his wife's murder and is now on trial.

Defence barrister Tony Kimmins told the jury it would become clear to them his client was a sexist, selfish and vulgar philanderer.

"But that doesn't prove a person is a murderer," he said.

Mrs Chardon was raised in the port city of Surabaya on the Indonesian island of Java. She met Chardon around the year 2000 and married him a month later.

Their marriage began to break down in 2009. They separated in 2012, but stayed under the same roof with their two young children while having affairs.

In December that year, two months before Mrs Chardon was last seen, she told her mother and her brother she was afraid.

It is unclear what she was afraid of, but she told them his gun had gone missing.

"She felt very scared and she cried," Mrs Chardon's mother Estralita Aler said via video link from Indonesia.

It was around the same time a man employed by Chardon at his Loganholme business came across a box with Chardon's name handwritten on it.

He recognised his boss' writing and found a gun and loose ammunition inside.

On the night Mrs Chardon returned home from a dinner with Ms Wong, Chardon drove to his Loganholme factory where he spent 80 seconds inside before leaving again.

Mr Green told the court Chardon could not explain why to police.

Another employee was asked to collect a box from one of Chardon's adult daughters and take it to the home of another.

She was told the box contained gun parts and handcuffs.

The trial continues.
