Australian Journalists Association

The Australian Journalists Association (AJA) was an Australian trade union for journalists from 1910–1992.

In 1913 the Australian Journalists' Association merged with the Australian Writers' and Artists' Union. This union had been formed in 1910, launched on 9 September of that year in the Sydney Trades Hall by Harold Mercer (1882–1952), also known as Harold St Aubyn, a prolific writer who was involved in the creation of 28 new unions in total.

On 18 May 1992 it amalgamated with Actors' Equity and the Australian Theatrical and Amusement Employees' Association to create the Media, Entertainment and Arts Alliance. The AJA section is now known as MEAA Media.
