There is a valid point to reminding he had made the "should throw you off the balcony" comment.
In light of that I might review my position.
It could be argued
1. She didn't know him
2. He had the strength to do it, so
3. She wouldn't wait to give him the opportunity.
4. In a drunken state climbing to the next level looked doable.
hmmm
I need to correct myself too. "Should" is a red herring introduced by me. Not intentionally.
Here is the quote from the audio.
"You're lucky I haven't chucked you off my balcony you goddamn psycho little bitch," Mr Tostee said.

The same article explains how the prosecution are pursuing the charges.
It is not alleged he threw or pushed Ms Wright but that he intimidated and threatened her so greatly she felt the only way to escape from him was to climb down from his balcony.
