Australia captain Mile Jedinak scored a penalty for the third successive World Cup game to earn the Socceroos their first Group C point against Denmark.
Christian Eriksen put Denmark ahead with a super finish after Nicolai Jorgensen's clever lay-off.
Australia levelled through Jedinak's controversial penalty awarded after a video assistant referee (VAR) review, according to BBC.
Yussuf Poulsen's close-range handball was analysed on video before the referee pointed to the spot.
In an absorbing encounter, Aston Villa's Jedinak sent Kasper Schmeichel the wrong way for his second goal of the tournament.
Aaron Mooy's went close from distance for Australia before Denmark's Pione Sisto was left holding his head after a curling shot from outside the area flashed just wide.
The point was enough to take Denmark to the top of Group C on four points, one ahead of France who plays Peru shortly.
Australia can still advance to the knockout stage.
