The sole witness for Friday is Detective Chief Inspector Glen Browne, who was manager of the NSW missing persons registry when Caddick vanished.
Det Insp Browne also fronted the inquiry last year where he explained many of the people who go missing on the NSW coast are never recovered.
Caddick stole millions through an investment scam, using the money to fund a lavish lifestyle.
Police and ASIC investigators raided her Dover Heights home on November 11, 2020, two days after she was reported missing by husband Anthony Koletti.
The 49-year-old's decomposing severed foot washed up on a beach on the south coast of NSW three months after her disappearance, leading authorities to presume her dead.
The NSW Police officer-in-charge of the investigation into her disappearance, Detective Sergeant Michael Foscholo, told the inquiry last year he believed the fraudster took her own life.
"It was clear to me Melissa Caddick's fraudulent activities were one of the catalysts for her disappearance and ultimately the reason, or motive, as to why she committed suicide," Det Sgt Foscholo said.
Caddick's eastern suburbs home was sold last month for close to $10 million, which liquidators deemed a strong result.
An extensive collection of jewellery once owned by the fraudster has also attracted large sums, with a recent auction garnering $800,000 that will go towards paying back victims.
