I am that girl: The case that put sexual consent on trial.

On Monday night, the young woman at the centre of one of Australia's most controversial rape trials talks to Four Corners.

"The 18-year old in the story is me. Those awful things happened to me. I am that girl."

She was a teenage virgin on her first night out in Sydney's King Cross. He was the son of a wealthy night club owner. They met on the dance floor. Minutes later, he ushered her out into a laneway. What happened next has had devastating consequences for both of them.

"Was a sick night. Took a chick's virginity, lol." Text message sent by the young man

The young man had sex with the teenager, without her consent, but the court found it wasn't rape.

"Whether or not she consented is but one matter. Whether or not the accused knew that she was not consenting is another." Judge

The man's acquittal, on the grounds that he didn't know the teenager had not consented, shocked many and provoked troubling questions about how the law interprets consent in rape cases. The young woman says she's still haunted by the ordeal.

"It got to be over for everybody else. There's no other avenues. Everyone's done, everyone goes home, and then it's just me. And I'm still here…I'm still living it."

Under the law, the young woman's identity has been kept secret. Now she has chosen to speak to Four Corners in the hope that others will learn from her experience.

"I've spent far too long feeling embarrassed and ashamed."

In a searing interview, she talks of how the incident and the years of legal action have impacted on her life.

"No-one dreams of their first time being in an alleyway with someone whose name they can't even remember."

This shocking account serves as a serious warning about the need to understand what consent is and the consequences of getting it wrong.

"The criminal law is a blunt and brutal method of social education...You shouldn't have to rely on the criminal law as the key mechanism for doing that." Barrister

One of those responsible for drafting those laws is now calling for change.

"There has to be some way to ensure that this ‘reasonable belief' as to consent concept is a bit more foolproof." Law professor

This episode of Four Corners screens a shortened version of the 2017 human rights documentary Complicit, directed by Heather White & Lynn Zhang.

Filmed over 3 years it investigates the Chinese workers paying the price for our mobile phone obsession.

"There were iPhone screens and Nokia screens…I held the phone screen in my left hand, and a piece of cloth in my right hand… Wiping was the only thing I did besides eating and sleeping." Teenage worker

Mobile phones, smartphones and tablets have revolutionised the way we communicate but the technology we are addicted to has had toxic consequences.

"I knew we worked with chemicals, but I had no idea that it's poison." Young worker

China produces approximately 90% of the world's consumer electronics. The factories making the components for these electronic goods are filled with young workers. Some have been exposed to poisonous chemicals, with devastating results.

"Many co-workers developed the exact same symptoms. When I walked, it looked like I had uneven legs. It would take 10 minutes to take a two-minute walk. My legs felt too heavy to move." Worker

This investigation, filmed secretly over four years, exposed the use of harmful chemicals in the factories producing the products many of us use. Hidden cameras captured the working conditions inside the factories churning out these products.

"It was the cleaning solution he used, which contained benzene, when he was working at the electronics factory that caused his disease." Father of sick worker

The film charts the growing realisation amongst the workers that their illnesses stem from their work and follows their fight for compensation.

"After we discovered so many workers with leukemia…more media reports followed up and showed that these workers were chemically poisoned." Worker activist

The landmark investigation led Apple to ban the use of benzene, a known carcinogen, and n-hexane, a chemical that damages the nervous system.

But the ban does not apply to subcontractors who make up two-thirds of Apple's supply chain. And around 500 other chemicals are still used to produce electronics, mostly in the developing world, where there are few or no regulations to protect the workers who make them.

"Many of the workers that I've helped got occupational diseases due to exposure to toxic chemicals. Many are from the electronics industry. They made cell phones, computers, semiconductors etc." Worker activist
