Cricket's world body fined Warner 75 per cent of his match fee for an altercation with South African wicket-keeper Quinton de Kock in the first Test this week.
CCTV footage showed him apparently turning on De Kock as the players walked up a staircase during the tea break in the fourth day of the match here.
The footage shows Warner being restrained by teammates Usman Khawaja and Nathan Lyon before being persuaded to go into the dressing room by Australia captain Steve Smith.
De Kock was also charged by the ICC but is contesting and will have a hearing later today.
After a feisty game that saw Australia take a 1-0 lead in the four-Test series, visiting off-spinner Nathan Lyon was also fined 15 per cent of his match fee after appearing to drop the ball on AB de Villiers after the batsman was run out.
