Here's what you need to know this morning.
Faulty heater causes gas leak
Three people have been taken to hospital after a gas leak at a house in Sydney's west.
Fire crews were called to the home in Rosehill, where they found three people who were extremely unwell, following reports of a gas leak just after 10pm last night.
A man and a woman in their 70s, and a man in his 50s suffered carbon monoxide poisoning and were carried from the home.
The cause of the gas leak is believed to have been a faulty heater.
New South Wales Fire and Rescue says people should check their heaters because carbon monoxide poisoning can be deadly.
Rail dispute hearing due to start today
A two-day hearing gets underway today in the Fair Work Commission in the long-running dispute between the rail union and the state government.
Last week, the union applied to the commission for an urgent hearing after threats from Premier Dominic Perrottet to tear up their enterprise agreement up if industrial action continued.
The Premier reiterated the message yesterday, adding that he would apply to the commission to terminate the agreement if strikes and other action continued.
Minister for Regional Transport Sam Farraway, who has taken part in the rail talks, said the dispute needed to end.
"The reality is the commuters of Sydney, and also all of New South Wales, they are over this," he said.
"They have had a gutful. This needs to be brought to a head and dealt with."
The union's Alex Claassens said the union would obey the commission's ruling.
"We have always been very comforted by the fact that we understand how the Fair Work [Act] acts. We've always worked within it," he said.
Investigation launched after tram and fire truck crash
Investigations are continuing into a collision between a fire truck and a light rail tram in Sydney's Haymarket yesterday.
The crash happened about 10:40am at the intersection of Eddy Avenue and Pitt Street, creating traffic chaos for parts of Sydney's southern CBD for several hours, as emergency crews tried to clear the damaged tram.
By 6:30pm, the carriage had been removed and taken to Randwick depot in Sydney's east.
Two people were taken to hospital: a 71-year-old woman with back injuries and a firefighter as a precaution.
Fire and Rescue NSW says it's conducting an internal review, while NSW Police investigates the cause of the crash.
Eighth MP announces retirement
The number of government MPs who are bowing out of politics at the next state election has risen to eight after speaker Jonathan O'Dea announced his impending retirement.
Mr O'Dea has held the blue-ribbon Liberal seat of Davidson, on Sydney's lower north shore, since 2007 and has been the Speaker since the last election.
"It has been an enormous privilege to represent the people of New South Wales alongside my parliamentary colleagues," he said.
"I will now seek new opportunities in moving to the next phase of my working life."
Premier Dominic Perrottet praised Mr Odea's commitment to his electorate, saying he had been a very successful advocate.
The Customer Service Minister Victor Dominello, Corrections Minister Geoff Lee and former water minister Melinda Pavey are among the Coalition MPs who will not be recontesting their seats on March 25, 2023.
Gay hate inquiry calls for public's help
A NSW special commission into gay hate crimes committed decades ago is calling for people with any information to come forward.
The inquiry, launched in April, is looking into unsolved deaths between 1970 and 2010, with extensive powers, including to compel witnesses.
A team of investigators has been analysing more than 100,000 documents but Senior Counsel Assisting the Inquiry Peter Gray SC says it's critical anyone with information comes forward.
"Any recollections or pieces of information that you might have, however major or minor, could provide a vital link in understanding what happened," he said.
"This may be the last chance for the truth about some of these historical deaths to be exposed. We need to hear from you."
This inquiry particularly wants to hear from those who may have been involved in the deaths of an LGBTIQ person, urging them to "make amends" and "break their silence".
The first public hearings are expected to take place in October and November.
