The 32-year-old was arrested after she climbed on top of a truck and lit a flare as the vehicle was parked in a southbound lane about 8.30am on April 13.
Coco was jailed on charges of disrupting vehicles on the bridge,possessing a bright light distress signal in a public place,and resisting or hindering a police officer in the execution of duty.
She was further convicted of using an authorised explosive not as prescribed and failing to comply with directions and also fined $2500.
Coco appeared via video link on Tuesday from Silverwater prison,wearing a dark green jumper,as her lawyer Michael Blair made a bail application in the District Court.
Prosecutor Nicholas Leach said bail was opposed due to unacceptable risk which was “two-fold”:failure to appear and endangering the community.
Leach said the Crown accepted Coco had no record of failing to appear for proceedings,but the risk came from the recent imposition of a custodial sentence.
