More than 10,000 cannabis plants have been seized by police in the central district for the second year in a row.
Police have labelled their haul a success, with 10,244 plants uncovered in the year to April following 10,134 cannabis plants being seized the year before.
"The total number of plants seized this year is outstanding," Detective Senior Sergeant Keith Borrell said.
"The operation has been a success and the significant amount of public support we have received has been a major contributor to this."
Last year's haul included 5918 plants discovered in aerial searches using Air Force Iroquois helicopters while the remainder were located during the execution of search warrants.
