Here's what you need to know this morning.
Hawkesbury man's death suspicious
Homicide detectives are appealing for public assistance after a man's decomposing body was found in the Hawkesbury River.
Hongli Qi was last seen by his family at Sydney's Town Hall around 1:00pm on May 11.
CCTV footage showed the 28-year-old leaving an apartment complex on Macquarie Street later that evening.
On August 16, police were called to bushland in Blaxlands Ridge, after council workers discovered a decomposing body.
The body has since been identified as Mr Qi.
Homicide Squad Commander, Detective Superintendent Danny Doherty, said police were treating the death as suspicious.
"His disappearance was completely out of character. His body was found some 80km from where he was last seen," Superintendent Doherty said.
"We have a strong belief that Hongli has been the victim of foul play."
Double murder investigation appeal
Police are asking for public help as they continue to investigate the double murder of a father and son in a gangland shooting in Sydney's west.
Salim Hamzy, 18, and his 64-year-old father Toufik were found slumped inside a ute on Osgood Street in Guildford just before 9:00am on October 20 last year.
Police have revealed they arrested a 25-year-old man in Merrylands in July, and charged him with accessory after the fact to murder and refused bail.
A 17-year-old was charged with possession of an unauthorised prohibited firearm after police seized a gel blaster at a home in Merrylands West.
Police have forensically examined a grey Ford Mustang and a burnt-out Lexus SUV — both believed to have been used as getaway vehicles in the murders.
Detective Superintendent Danny Doherty said anyone who saw either vehicle before or after the murders should speak to police.
"Strike Force Ormerod detectives were out again yesterday, canvassing the Marayong, Granville and Yagoona areas, attempting to piece together the movements of both the Ford Mustang and the Lexus SUV prior to and following the shooting, Detective Superintendent Doherty said.
Verdict in Chris Dawson murder trial due today
A Sydney judge is today expected to deliver his verdict in the murder trial of former teacher Chris Dawson.
Justice Ian Harrison has presided over the two-month trial without a jury.
Mr Dawson, now 74, is accused of murdering his wife Lynette who he reported missing in 1982.
The crown case was that he murdered her to have unfettered access to his student girlfriend, who was the family babysitter at the time.
The defence case was that he had no motive to kill his wife.
The trial heard there were five alleged sightings of Ms Dawson after she went missing. Her body has never been found.
Planned rail action goes ahead as talks resume
After marathon talks between transport officials and the rail union there's been progress in negotiations but no deal struck, with rail commuters bracing for more disruption today and tomorrow.
Dozens of trains have been cancelled this morning.
Commuters on the T2 Inner West & Leppington, T3 Bankstown and T8 Airport & South Lines are experiencing the worst impact with large service gaps of more than 30 minutes in some areas.
The rail union is set to provide an update on the progress of its negotiations with the NSW government just before 10:00am this morning.
Transport Minister David Elliot is due to join the negotiations on Wednesday.
He accused the union of engaging in "thuggery" and "guerilla warfare" yesterday, while the union labelled the government's latest offer to resolve the dispute as a "stunt".
Tomorrow's planned industrial action involves a ban on operating foreign-made trains — which make up about 70 per cent of the fleet.
It will definitely proceed, regardless of today's talks.
The ABC understands the union responded to the letter from the government at yesterday's meeting.
The union's Alex Claassens said, "the ball is now in the government's court".
Treasurer backs boost to income threshold for pensioners
New South Wales Treasurer Matt Kean has backed a push for changes to pension income thresholds to enable more older Australians to work without being financially penalised.
Federal Opposition Leader Peter Dutton recently floated reforms to the pension system which pensioner advocates have long campaigned for, and wants it discussed at this week's jobs summit in Canberra.
Single pensioners can currently only earn up to $490 dollars per fortnight without their pension being affected.
Mr Kean says the Federal Government should consider changes to pension income thresholds to address chronic labour shortages across the country.
"We have a grey army of workers who want to get out there and they want to work, but there is no incentive to do so," he said.
"It's a win for our pensioners who would benefit from the extra work and socialisation, and also for businesses who would be able to plug some of their vacancies."
