T-levels will allow 16 to 19-year-olds to study in 15 sectors in subjects like hair and beauty or construction.

Sexual assault counselling services around the country have disclosed that the number of calls for help from female university students increases during and immediately following Orientation Week events at Australian universities.

Ray is from the Western Arrernte clan and has loved cartoons, video games, Marvel comics, and characters like Superman since childhood.
