Former prison guard Sharon Yarnton, 49, has been given bail more than 18 months after she was accused of attempting to murder her husband Dean.
Some time later he woke up alone inside the passenger seat of his Nissan Navara in the Georges River National Park at Picnic Point and found a gas bottle placed inside the car and fuel poured around the outside.
She is accused, along with two others, of placing the bottle there as part of a murder plot.
During an appearance in the NSW Supreme Court on Friday she was granted strict conditional bail.
Acting Justice Peter Hidden ordered as part of her bail conditions that she must stay at an address approved by the court and cannot leave at all unless she is accompanied by her mother and father.
She will also have a strict curfew and must report to Kogarah police station daily.
She is not able to apply for a passport and is not to approach or contact the complaint.
Mrs Yarnton had previously been held in Silverwater women's jail in segregation due to her former occupation as a senior corrective services officer.
Her trial is expected to begin in April.
