A children's swimming pool was used to water cannabis plants worth almost $1 million at a Bulli property.
Drug squad officers yesterday released pictures of the 969 cannabis plants, worth about $970,000, which were seized on Tuesday from an Appin Rd property at Bulli Tops.
The property was so isolated that officers had to fly in by helicopter.
Cannabis crop was the size of a football field Police had been tipped off by the public about the crop growing in bushland and it is believed that those responsible had gone to a significant amount of effort to grow the illicit weed.
The site was irrigated, with PVC piping running water from nearby Cataract Dam to the large crop.
A generator and pump sent water to a children's swimming pool, which used gravity to feed the plants.
Much of the undergrowth had been cleared in an area the size of a football field and it had been fenced with chicken wire to a height of more than 2m.
The soil had been prepared and fertilised for the cannabis seedlings with holes dug 2-3m apart.
No arrests have yet been made.
