An Australian woman accused of sending nude photos of herself to a teenage girl in Tennessee has been freed from a US prison on $US30,000 ($A32,255) bail.
Rianne Gysberts agreed to surrender her Australian passport to gain her freedom.
The 31-year-old receptionist from Frankston, Victoria, was arrested on Friday when the alleged 17-year-old victim's mother discovered Gysberts was in their home town of Jackson, Tennessee.
"It's our belief that she was going to take this relationship as far as it could go," Captain Tyreece Miller of the Jackson Police Department told Tennessee TV station WBBJ.
Gysberts was in the US for a family event, but diverted her travel plans to Jackson after meeting the 17-year-old in an internet chat room about a month ago, authorities alleged.
Capt Miller said plain-clothed officers staked out a McDonald's restaurant on Friday and when Gysberts arrived they placed her in handcuffs.
The Australian was charged with one count of solicitation of sexual exploitation of a minor for sending the nude photos of herself to the girl.
"I believe she was pretty serious about this young lady because she had actually brought a promise ring and a cell phone to give her, so they could communicate without her mum knowing about it," Capt Miller said.
A tired Gysberts, in a dark blue prison uniform, her hands shackled, and surrounded by other inmates, appeared via a videolink from Madison County Jail during Monday's arraignment.
The judge set Gysberts' bond at $US30,000 and ordered her to surrender her passport.
She posted bond and was released, with her next court appearance set for October 10.
