Police have seized more than $3.5 million worth of cannabis in raids on another five homes in Sydney's west.
Seven people have been arrested after raids on homes at Oxley Park, St Mary's and Colyton uncovered more than 1500 cannabis plants as well as hydroponic equipment.
An 18-month-old boy inside one of the Oxley Park properties has been removed from his parent, who were among those arrested.
The raids are part of Operation Yalamba which led to the seizure of $1.6 million worth of cannabis on the weekend and another half a million yesterday, all in the same area.
Police have not yet commented on whether these raids were connected to the Blair Athol raids last month.
Assistant Commissioner Dennis Cliford says there will be more raids, and has issued a warning to anyone involved in manufacturing drugs.
"They can rest assured if they want to engage in illegal activities such as cultivating drugs, then sooner or later they'll get a knock on the door from police."
Another two men are also assisting police with inquiries.
