Australian Border Force investigators have fished out a package containing more than 9.5kgs of ephedrine hidden in dried seafood.
ABF officers came across the suspicious package, which was sent via express mail from China, at the Sydney mail gateway facility on 8 July.
X-rays of the package revealed anomalies, prompting the officers to do a physical inspection, which revealed 19 packets of ephedrine inside.

After the intercept, officers executed search warrants at properties in West Ryde and Rydalmere, where they seized an additional package of ephedrine weighing 9.5 kilograms and a BB gun.
Authorities say the combined street value of both seizures is estimated to be $1.9 million.
A 37-year-old Chinese national has since been arrested and charged with importing a commercial quantity of a border-controlled precursor.
The man appeared before Parramatta Local Court on 11 July 2017 and was remanded in custody to reappear on 22 August.
Ephedrine is used as a precursor agent in the manufacture of illegal amphetamine substances, such as ice.
