1. “She was incredible.” Friends and family mourn Sydney CBD attack victim Michaela Dunn.

The Sydney woman who police believe was the first victim of the alleged CBD stabbing rampage has been described by a friend as “incredible”.

Michaela Dunn, 24, from Sydney’s inner west, was found with a laceration to her neck in a Clarence Street unit on Tuesday afternoon.

Mert Ney, 20, is accused of killing her before allegedly stabbing 41-year old Linda Bo at the Hotel CBD and wandering York Street with a knife. He was detained by members of the public.

Police believe Ney attended the Clarence Street apartment for “the purposes of prostitution”, where Dunn’s body was later discovered.

Her mother, Joanne Dunn, toldNineshe was a “beautiful girl from a beautiful family” and “very much loved”.

She’s been described by one friend as “incredible” and a “true delight”.

“I’ve known this girl since she was just a kid in high school at 14. Her sister and I were together for 6 years, and Mikki was like my baby sister. I cannot describe how sad and how broken I am at this moment. I loved this kid. She was incredible,” Joan Westenberg said on Twitter.

The 24-year-old had a passion for travelling and last year travelled to Fiji with friends, where she donated school supplies to Fijian children.

Dunn, who was a former Rosebank College student and studied at the University of Notre Dame, also rallied against sexual violence in a Facebook post several years ago.

"Sexual violence and harassment is never acceptable. Take two minutes to read and sign this petition, it's such an important issue that needs to be addressed sooner than later," she wrote on a post in 2016.

A University of Notre Dame Australia spokesman said the community was "shocked and saddened" by the tragedy and extended its condolences to the 24-year-old's family and friends.

Australia's peak sex worker organisation and a NSW sex worker community group said in a joint statement they are "devastated" by the alleged "random and senseless acts of violence".

"Michaela Dunn was a woman, a community member, and a whole individual who will be missed and mourned," Scarlet Alliance, Australian Sex Workers Association and the NSW Sex Workers Outreach Project said in a statement.

"We offer the victim's family our deepest and most sincere condolences at this time. Our collective hearts are heavy."

Australian Muslim leader Mohamad Tawhidi also expressed his condolences.

"The nation is shocked and heartbroken. This could have happened to any one. RIP," Imam Tawhidi said on Facebook.

Homicide detectives are expecting to charge Ney with murder and serious assault.

Ney remains under police guard at Royal Prince Alfred Hospital and is yet to be interviewed by police about the incident that brought the city's streets to a standstill.

2. Jeffrey Epstein accuser sues his estate.

Epstein accuser Jennifer Araoz: “I used to feel alone, walking into his mansion with the cameras pointing at me, but now I have the power of the law on my side. I will be seen. I will be heard. I will demand justice.” https://t.co/kXdqstyseu

A New York woman who says she was sexually assaulted by Jeffrey Epstein at the age of 14 has sued the disgraced financier's estate and a former associate, as prison officials began an internal review of how Epstein died.

In the first of an expected wave of lawsuits, Jennifer Araoz, 32, said she had just entered high school in 2001 when an Epstein associate brought her to the financier's mansion on Manhattan's Upper East Side.

It was the beginning of a grooming process that led to months of sexual abuse including a "brutal rape".

The lawsuit in New York County Supreme Court is among the first of a series by women made possible by the state's Child Victims Act, which opened a one-year window to sue over alleged sexual abuse regardless of how long ago it occurred.

Epstein, who once counted US President Donald Trump and former president Bill Clinton as friends, was found unresponsive in his cell on Saturday morning at the Metropolitan Correctional Center in lower Manhattan.

The well-connected money manager apparently took his own life.

Psychologists on Tuesday began studying how the suicide occurred, according to a person familiar with the matter.

Another team at the MCC on Wednesday began an "after action" review, which is normally triggered by significant events such as the death of a high-profile inmate, the person familiar with the matter said.

The reviews are separate from investigations by the FBI and US Department of Justice's inspector general.

Epstein was arrested on July 6 and pleaded not guilty to charges of sex trafficking involving dozens of underage girls between 2002 and 2005.

Prosecutors said he recruited girls to give him massages, which became sexual in nature.

Araoz's lawsuit says former Epstein associate Ghislaine Maxwell facilitated Epstein's abuse of several girls by overseeing their recruitment and "ensuring that approximately three girls a day were made available to him for his sexual pleasure".

The other three unnamed defendants in Araoz's lawsuit - all women who allegedly worked for Epstein in New York - are a maid, a secretary, and a "recruiter" who helped procure underage girls for him.

Araoz told reporters on a conference call she was angry that Epstein's death meant he would never face her in court.

"Today is my first step toward reclaiming my power Jeffrey Epstein and his enablers stole from me," she said.

"They robbed me of my youth, my identity, my innocence and my self worth."

The complaint described Epstein's massage room as having a ceiling painted as a blue sky with clouds and angels, "to give the appearance that you were in heaven".

It also detailed a variety of alleged misconduct by Epstein, including what she called an insinuation that she owed him because of the money he paid her.

"I take care of you, you take care of me," the complaint quoted Epstein as saying.

3. "There is no place for racism." NRL star Latrell Mitchell speaks out against racist trolls.

Latrell Mitchell says Sunday's post was not the first time he has been racially abused as the NRL aims to ban fans from games if they vilify players online. https://t.co/lbTjyUWZ4s

Latrell Mitchell has spoken out against racist trolls as the NRL warned any fan who vilified a player online faced bans from attending matches.

Mitchell broke his silence on the matter on Wednesday night, days after publishing vile comments made against him on social media.

The star Roosters centre said he had also previously been a victim of racism, and that he would continue to out any person who abused him in such a way.

"For everything that's been going on the past couple of days has been so hard for my family and I," Mitchell posted on Instagram.

"But it wouldn't be the first time that this has happened. I would really love to take the time to thank everyone that sent me a message.

"There is no place for racism. It is 2019 I am a proud aboriginal man and I will continue to name and shame anyone that has an opinion against me or my race.

"I have had enough, we cannot keep allowing this 'casualness' to happen.

"Wake up Australia and stop being ignorant and just embrace everyone for who they are!"

Mitchell's comments come as the NRL continues to investigate the initial post made against the star Sydney Roosters centre on Facebook on Sunday.

It also emerged on Wednesday that Blake Ferguson was also racially vilified earlier this season, with the NSW winger alerting Parramatta to the offensive messages.

Club bosses on Wednesday discussed the issue at the NRL's CEOs meeting, and backed a stance to ban any person who racially abuses a player online from games.

"We've got an opportunity as a sport, to stand up and stand for something," NRL CEO Todd Greenberg said.

"And when we see it, we'll call it out.

"If we can find ways to make sure they're unwelcome in the game, whether that's a membership, simply buying a ticket, we'll do that.

"It's not easy (to find them). But we'll put some resources into it where we can.

"We've got a pretty sophisticated system in our integrity unit. We've got some smart people, and if we find them, we'll do something about it."

The NRL has previously banned fans who have racially abused players at grounds, most recently last season at Penrith after a slur made against Greg Inglis.

Greenberg also rejected suggestions players should simply avoid social media as a means to escape such online abuse.

"I've heard people say in recent days that the simple thing to tell our players is simply stay off social media. That's not the answer," Greenberg said.

"Social media is a part of the next generation, whether we like it or not. And some of that's very difficult for some young athletes to deal with.

"We're not going to stand by and allow our athletes to be racially vilified."

4. Court told of white sedan driving "crazily" at William Tyrrell inquest.

The inquest into William Tyrrell's suspected abduction has heard a disputed account about a car driving 'crazily' the day the boy went missing. https://t.co/BHJhI54lFH

Two former friends have told conflicting stories to the William Tyrrell inquest about whether a driver was seen pushing something down into a car footwell the day the three-year-old went missing.

William vanished while playing at his foster grandmother's home in Kendall on the NSW mid north coast on September 12, 2014.

Kendall man Tim Palmer told the boy's coronial inquest on Wednesday he'd had a conversation with friend Michael McInally in 2018 in which Mr McInally said he needed to get something off his chest.

He said on the day William Tyrrell went missing he saw a white sedan driving "crazily" down Batar Creek Road and the driver using his left hand to push something into the passenger side footwell, Mr Palmer said.

"He said if I was to tell anyone this story, he would deny it," Mr Palmer told the NSW Coroners Court.

Mr McInally then addressed the inquest and disputed several elements of Mr Palmer's story.

He said in fact, he'd been driving down Combyne Street when he saw a person holding their left hand up as if to get better phone reception.

Asked by the coroner why he would tell a story in 2018 about how he saw someone in 2014 trying to get phone reception, Mr McInally said: "I don't know."

"I was in a drunken state," he said.

"I don't remember half of the conversation."

But Mr Palmer's version was wrong, he said.

Mr McInally said he remembered the car as he'd never seen it in the area before.

Mr Palmer said he believed his decision to tell police about the 2018 conversation led to the long-time friends falling out.

The inquest resumes on Thursday, in closed court.

5. AFL great Graham 'Polly' Farmer dies aged 84.

Thoughts with the family and friends of legendary Geelong ruckman and #AFL Legend Polly Farmer, who has died in Perth aged 84. He changed the way big men play the game. https://t.co/aRgkxWH7XN #RIP pic.twitter.com/e4VWIZPcpF

Champion Australian Rules footballer "Polly" Farmer was once asked if his nickname had earned him undue attention when he started playing in Perth in the 1950s.

"It could have been worse, they could have found out my middle name," Farmer said.

But Graham Vivian "Polly" Farmer didn't need to explain himself to anyone.

Farmer, who died aged 84, was a sportsmen with few equals, a revolutionary player and an inspiration to generations of indigenous footballers.

Born in Fremantle and orphaned before he turned two, Farmer was brought up in a Perth orphanage run by the protestant nun Sister Kate where he received the name "Polly", supposedly because he talked a lot.

Farmer's introduction to football was at Sister Kate's, where he remained until he was 14, and was developed later when he moved to Greenbushes in south-western WA and acquired a shoe, just the left one, and learned to kick.

In 1953, a
