Here's what you need to know this morning.
Major train delays across city
Train commuters across New South Wales are being warned to expect major disruptions across the rail network today because of strikes.
As of midnight, rail workers began industrial action for 24 hours by not operating foreign-made trains.
The action means a disruption to around 70 per cent of the rail fleet.
Transport for New South Wales has advised commuters that this will impact most of the city and suburban network, with at least a 30-minute gap between services.
Sydney Trains chief executive Matt Longland said the action would make the day "difficult".
"We know how difficult this period has been," he said.
"What we've seen is the unpredictable impact of some of the action … We're doing our best, we're going as efficiently as we can to work through the issues.
"I think there is goodwill among all of the unions to get an outcome."
Commuters are being advised to avoid non-essential travel.
Both the Rail, Tram, and Bus Union and the NSW government are expected to continue negotiations.
Bus drivers to stop work for several hours
Bus drivers across some parts of Sydney's inner-west and south will take industrial action for six hours today due to a dispute with a private bus operator over pay and conditions.
Members of two unions who drive for private bus company Transit Systems will strike from 4:00am until 7:00am, and then from 2.30pm through until 5.30pm.
The affected region covers an area stretching from Rockdale in the south to Olympic Park and across the inner-west and parts of the CBD.
Richard Olsen from the Transport Workers Union said pay and safety concerns were behind the strike action.
"We've had around nine deaths over the past few years involving the bus industry," he said.
"We say that is because of poor rostering, the length [of shift] of anything up to 13 hours is far too long."
Missing teen from Surry Hills
Family and police have serious concerns for a missing 14-year-old boy.
Jerome Sykes was last seen at his high school on Chalmers Street in Surry Hills at 8:10am last Thursday.
The teen failed to return home from school and his family contacted police on Monday.
He is known to frequent Surry Hills, Redfern, and the Penrith areas, and is believed to have been seen near Central Station as recently as Monday.
Jerome was last seen wearing a blue and black jumper, navy blue school pants, and red or bright orange shoes.
Fire season kicks off with warning
The NSW Rural Fire Service [NSWRFS] has warned that while it is unlikely the state will see a fire season like the Black Summer bushfire disaster this year, potential fire risks should not be underestimated.
The fire season officially kicks off in some parts of the state from tomorrow with the start of Spring.
A new nationally consistent fire danger rating system will also come into force with four levels of danger and simple actions that should be taken at each rating level.
NSWRFS spokesman Ben Shepherd said while the wet weather seen this year had lessened the risk of another catastrophic fire season ahead, things can heat up and dry out quickly.
"What we don't want people to think is that fires need to be of that magnitude to be problematic, because in and around urban areas a smaller fire of perhaps 10 or 20 hectares can quickly impact on homes and quickly cause danger to lives," he said.
Smoke from a hazard reduction burn in the Blue Mountains National Park south-west of Glenbrook may affect areas of Greater Sydney on Wednesday and Thursday, but is expected to clear throughout Friday, the NSWRFS said.
