Dr Michael Swanson said it will aim to steady ambition and restore confidence.

A man who killed two Asian migrant sex workers will spend more time behind bars after prosecutors successfully appealed his sentence.

Chinese student Xiaozheng Lin, 25, was originally jailed for 14 years for the manslaughter of Yuqi Luo, 31, and Hyun Sook Jeon, 51.

But the Victorian Court of Appeal today re-sentenced him to 18 years behind bars after finding the original term was "manifestly inadequate".

Luo and Jeon were both sex workers who operated out of their apartments in Melbourne.

Lin had sex with Luo at her La Trobe Street apartment in the early hours of December 27, 2022, before asking for more services.

When she told him it would cost another $100, Lin became enraged and pushed Luo onto the bed, before strangling her until she was gasping for air.

He left her for dead, stealing $7000 in cash along with other personal belongings, including her mobile phone, tablet and handbags.

Lin told his friend he had sex with Luo, robbed and assaulted her after she had bitten his hand, and claimed she was alive when he left.

Later on December 27, between 10.15pm and 10.45pm, Lin visited Jeon at her Docklands apartment, where they had sex before he inflicted another deadly assault.

Lin left at about 12.37am, stealing her bank cards, laptop, phone, car and building keys, and then catching an Uber home.

It is unclear how Jeon died because her body was too decomposed to determine a cause of death at the time of autopsy.

Lin was facing a murder trial but cut a deal with prosecutors, instead pleading guilty to two counts of manslaughter in October 2024.

He was sentenced the following month to a maximum of 14 years behind bars with a non-parole period of nine years.

Prosecutors appealed the sentence in June 2025, arguing it was manifestly inadequate given the seriousness of the offending and Lin's high moral culpability.

And appeal justices Lesley Taylor, Peter Kidd and Jane Dixon agreed, today finding the offending called for a stern punishment.

"The objective gravity and moral culpability in respect of each offence was high, and the stark feature of this case was the loss of life by, not just one, but two defenceless women," the written reasons stated.

"In our view, each of the individual sentences was outside the range reasonably open to the sentencing judge in all the circumstances."

The justices also found the non-parole period was manifestly too low, given Lin was not found to have good prospects of rehabilitation. They increased it to 14 years.

An Australian businessman who was jailed for insider trading is now among the country's richest people after cashing in on the artificial intelligence (AI) boom.

Oliver Curtis walked out of a NSW prison on June 23, 2017 after serving 12 months of a two-year sentence for conspiring to commit 45 illicit trades, which banked him and former pal John Hartman $1.43 million.

Less than 10 years after his release, Curtis, 41, has made his debut on the Australian Financial Review (AFR) rich list with an estimated personal fortune of $1.25 billion.

Curtis has earned this impressive net worth through Singapore-based AI infrastructure start-up Firmus, which is on track for a nearly $7 billlion valuation after computer chip giant Nvidia doubled its investment last month.

The former investment banker is now the 125th-richest person in Australia, according to the AFR.

Curtis is in good company as a rich list debutant.

There are 15 other first-time entries, including the founders of chicken chain El Jannah and clothing brand White Fox.

His path to the rich list is one that is as well-documented as it is tumultuous.

Curtis, the husband of well-known public relations boss Roxy Jacenko, began Firmus alongside his cousin Tim Rosenfield in 2019.

Just nine years ago, Curtis was a newly-released parolee after a year-long stint at Cooma Correctional Centre.

He served the minimum sentence for insider trading, which took place between May 1, 2007, and June 30, 2008, resulting in a net profit of $1,432,228.85.

At the time, Justice Lucy McCallum said Curtis "shows no sign of progression beyond the self-interested pursuit of material wealth which prompted his offending".

The money was spent on luxury cars, a Bondi apartment and trips overseas.

His co-conspirator Hartman later became the Crown's star witness and served a 15-month sentence at Silverwater jail.

Curtis was back in business plotting his billionaire redemption arc within months of walking free and reuniting with Jacenko and his children.

Before Firmus, he co-founded cryptocurrency medical start-up e-Nome with his father Nick Curtis.

The company fizzled out quickly and Curtis then pivoted to AI, launching Firmus two years later in 2019.

Despite his criminal record, Curtis was given the green-light to run Firmus as a publicly-listed company in March this year.

Firmus is expected to float on the ASX by September.
