Police have uncovered a major cannabis plantation with an estimated street value of $2 million on the central Queensland coast.

Officers seized around 600 plants from the property at Baffle Creek between Gladstone and Bundaberg yesterday.

Detective Senior Sergeant Luke Peachy says it is a significant find.

"A bush can go for up to $3500 a plant so if you times that by nearly 600 then it is quite significant," Detective Peachy said.

"Anytime we find anyone producing a dangerous drug - whether it's cannabis or amphetamines or anything else - we treat it as serious.

"Obviously a find of this proportion is quite significant."

No charges have been laid at this stage.

"At this stage investigations are ongoing but no person has been charged yet," Detective Peachy said.

"We're quite confident that we have significant evidence that will link the persons of interest to this cultivation."
