Here's what you need to know this morning:
Second man arrested over drug haul
NSW Police have made another arrest as part of Strike Force Nilland, targeting shipments of illegal drugs.
Police arrested a 36-year-old man at Sydney International Airport and charged him, after 150 kilograms of pseudoephedrine was discovered earlier this year concealed in metal pallets, bags of desiccated coconut and hidden in mattresses.
The shipments — with a potential street value of $7.5 million — were destined for Sydney's streets.
The Seven Hills man was refused bail in Central Local Court on Wednesday and was expected to reappear in March.
Another 36-year-old man was arrested earlier this year and police allege the pair were working as part of a criminal syndicate.

US tourists advised to avoid Australia due to 'very high' COVID-19 threat
America's Centers for Disease Control and Prevention (CDC) has added Australia to a list of countries its citizens should not travel to due to COVID-19 risks.
The CDC has advised its citizens to "avoid travel to Australia", which it says poses a "very high" risk of infection.
Australia is now ranked at level four on the CDC's risk assessment level — the highest level possible.
"If you must travel to Australia, make sure you are fully vaccinated before travel," the CDC's official advise states.
"Because of the current situation in Australia, even fully vaccinated travelers may be at risk for getting and spreading COVID-19 variants."
