Two young men accused of selling firearms and drugs to undercover police officers in western Sydney will remain behind bars for now.
Bilal Alameddine and Samimjan Azari, both 18, have each been charged with 17 drug and weapon-related offences after counter-terrorism officers arrested the pair following an operation on Friday.
The two had been monitored by authorities since last September, however in the past two months came under increased surveillance.
They allegedly sold seven firearms to undercover officers, along with almost half a kilogram of cocaine in May and June.
It's also alleged the pair supplied more than 150 rounds of ammunition - including .22 calibre and 7mm calibre cartridges.
Following their arrests, police raided three properties in Merrylands and Toongabbie and also found another gun, cash, illicit drugs and an imitation police vest.
Alameddine and Azari did not appear at the Parramatta Local Court on Thursday where their lawyer Abdul Saddik did not apply for bail and it was formally refused.
The pair is due to appear via an audio-visual link when the matters return to court on August 31.
