Note: This story discusses sexual assault.

Who had a duty of care for Kate the night she was allegedly raped by Attorney-General Christian Porter? She was just 16 and Porter was 17. They were school students, having travelled from their home states of South Australia and Western Australia to Sydney for a debating tournament.

If was meant to be a fun trip for the students: lots of dinners and dancing and debating, as well as underage drinking and partying in pubs. It seems unlikely in today's Sydney that a group of students would be able to drink in bars unchaperoned.
