UPDATED: ROMA'S biggest ever drug bust operation is expected to put a "significant" dent in the flow of illegal drugs into the Maranoa, according to police.
While he couldn't go into details of the operation, South-West Detective Inspector Kerry Johnson said the operation could not have been possible without the support and co-operation of the wider community.
"It was a broad section of the Roma community [that were charged]," he said.
"It is a major dent on the persons profiting on people's pain. Every area our community functions, they are cruelling the lot of us.
"The moment you remove these people, it allows residents to breathe.
"Roma is a very good community and that's the only way we could be successful - because the community assisted us."
Only one of the 20 people charged as part of the operation applied for bail in the Roma Magistrate's Court yesterday.
The most concerning parts of the drug operation revolved around the selling of drugs to children, according to Det Insp Johnson.
"There's a 17-year-old charged with drug trafficking and there's also charges of supplying to dangerous drugs to a minor, which is very concerning," he said.
EARLIER: A YEAR-long drug operation -- the largest ever conducted in Roma -- has led to charges for 20 people relating to trafficking, supplying, and a range of firearm offences.
Named "Operation North Dewdrop", the sting involved detectives from the region, along with State Crime Command Organised Crime, Stock and Rural Crime and Tactical Crime Squad.
When they struck today, police executed 23 search warrants across Roma homes and properties.
They unearthed large amounts of methylamphetamines, cannabis, cash and firearms.
Stolen property was also discovered.
South West District Detective Inspector Kerry Johnson said the arrests will have a significant impact on the supply of dangerous drugs in the South West District.
"This operation has been an outstanding success and will have a significant impact on drug supply within the district," Detective Inspector Johnson said.
"The distribution of these drugs pose serious health risks affecting the lives of our children and members of the community and we will continue the fight against drugs.
"The Queensland Police Service are committed to reducing the negative impacts of dangerous drugs on our community and we will continue to dismantle these networks."
