Mystery surrounds the 2019 Australian Football Hall of Fame, which begins at 8pm AEST on Tuesday night. 

Last year in November, the AFL Commission loosened the Hall of Fame criteria, which paved the way for the first female to be inducted.

Clauses relating to media and administrators being retired before they could be inducted have been removed.

The AFL Commission also changed the number of Hall of Fame inductees allowed in a year, which was previously set at six. Now as many as eight can be accepted.

Clauses relating to two 'recent player retirees' from the last 10 years being inducted have also been removed, while changes relating to eligibility for Legend status were made.

Now, one Legend may be crowned every two years, as opposed to the previous rule that dictated 10 per cent of all Hall of Fame members must be elevated to the Legend group.

The Hall of Fame's selection committee will also consider the elevation of a number of deceased candidates for Legend status ahead of its 25th anniversary in 2021.
