Here's what you need to know this morning.
Premier's trip overshadowed by parliamentary probe
The New South Wales Premier's first overseas trip in the role is being overshadowed by a parliamentary probe investigating how former deputy premier John Barilaro was appointed as the trade commissioner to the Americas.
Mr Barilaro's ex-chief of staff yesterday told the inquiry the former state Nationals leader lined up the New-York-based role before he retired from politics.
Yesterday, the Premier said he was not aware of Mr Barilaro making comments to that effect.
Mr Barilaro has strongly denied the allegation, labelling it fictitious.
Meanwhile, Drummoyne MP John Sidoti has rejected the Premier's call to resign, vowing to fight findings by the Independent Commission Against Corruption (ICAC) that he engaged in corrupt conduct by using his position to influence local councillors to benefit his family's property interests.
Mr Perrottet is in Japan, ahead of a visit to South Korea and India as part of a bid to strengthen ties in a 10-day trade mission.
Blaze at kebab shop
Fire crews have extinguished a blaze at a business at Lidcombe in Sydney's west.
Twenty firefighters were called to a kebab shop on John Street before 6am.
Crews are now searching the two-level building but the home above the business is believed to be unoccupied.
The cause of the fire is being investigated.
Heritage building damaged
Police have released CCTV of a man they wish to speak to about suspected deliberate damage to a heritage-listed building in Sydney's CBD.
Four fire hydrants were turned on a building on John Street in Ultimo at about 8pm on Thursday, June 30.
The structure suffered extensive water damage, estimated to be worth $500,000.
Police have released an image of a man they believe may be able to assist with their inquiries.
He is depicted wearing a face mask, a black hat with a white trim, and black clothing. He was carrying a backpack and duffel bag.
Anyone with information is asked to contact Crime Stoppers.
Police release image after fatal stabbing
NSW Police have released CCTV footage after the fatal stabbing of a teenager which police say may have been part of a dispute "over a girl".
Just before 3am on June 4, emergency services were called to Australis Drive at Ropes Crossing.
On arrival, police officers found a 16-year-old boy with a stab injury.
The boy died despite efforts to revive him.
"[There were] young boys, probably with some hormones running through their system, and someone thought they had to defend the right of their girlfriend at the scene and, unfortunately, it's led to a young boy being killed," Detective Chief Inspector Paul Tickner said.
The victim was at a house gathering with about eight people and he only met the suspected offenders on the night, police said.
Police have released CCTV images and a description of three boys they would like to speak to.
All three are described as aged between16 and 17.
One male is described as being of Caucasian appearance. The other two males are described as being of Aboriginal or Torres Strait Islander, or Pacific Islander or Māori appearance.
Anyone with information about the incident is urged to contact police or Crime Stoppers.
NSW Labor promises biosecurity commissioner if elected
NSW Labor is promising biosecurity threats like foot-and-mouth disease will be tackled by an independent commission if it is elected next year.
Opposition Leader Chris Minns said a biosecurity commissioner would provide independent advice and report to parliament each year.
Mr Minns outlined his plan for a strong agriculture and farming industry ahead of the March state election.
He said besides the existential threat of climate change, biosecurity, weeds and pests presented the most significant threats to the environment.
"A strong agriculture sector underpins the success of our rural and regional communities," he said.
"And our rural and regional communities underpin the success of our economy and our state."
Labor will also reinstate a dairy and fresh food advocate to monitor supply chains and food security.
RFS trucks to get digital upgrade
Digital technology is set to be fitted to more than 5,000 Rural Fire Service (RFS) trucks to protect crews and improve their response to emergencies.
The touchscreen mobile devices will allow personnel to send and receive information such as fireground maps, weather forecasts and potential hazards. Crews currently rely on radios.
RFS president Scott Campbell said providing accurate information over radios during emergencies could be challenging.
"It (the new technology) will definitely improve safety," he said.
"One of the things that came out of the Keelty inquiry was the ability to track trucks.
"Once all trucks are then on the GRN system, they will have that capability because currently we're reliant on a radio message.
"It'll be made so much easier with a data terminal because they will be able to see where you are."
NSW farmers urge ongoing commitment to biosecurity
The NSW Farmers Association says the discovery of fragments of serious livestock diseases in food products in Melbourne highlights the need for an ongoing commitment to biosecurity.
Federal Agriculture Minister Murray Watt confirmed foot-and-mouth disease (FMD) and African swine fever were discovered during routine testing of pork products from China.
The association's biosecurity chair, Ian McColl, said it was not just Indonesia that was battling foot-and mouth-disease.
"There's currently about 20 countries around the world that do have FMD, so while Indonesia is very important and Bali is important, it's important strategically that we recognise it's a threat on a much wider scale," he said.
