For basketball referees in Australia using the FIBA Official Basketball Rules 2026, in effect from 1 October 2026 (2026/27 season). Covers what changed in 2026, technical, disruptive, flagrant and disqualifying fouls, key violations, goaltending, crew chief duties, instant replay and the Basketball Australia officiating pathway.
The FIBA Official Basketball Rules 2026 take effect worldwide on 1 October 2026. The main changes are:
FIBA publishes the full rules, a separate Official Basketball Rules Interpretations document and a rule changes summary. The final text of the Official Basketball Rules prevails over the summary.

From 1 October 2026 technical fouls (Art. 36) are split into two categories by nature and severity:
Disqualification: a player after two category 1 technical fouls (or two flagrant, or one of each). A head coach after two category 1 technical fouls ('C') for personal unsportsmanlike behaviour, or three category 1 technical fouls arising from the bench ('B' or 'BD'), or a combination as set out in Article 36.2.4.
Penalty: the opponents get 1 free throw, administered immediately, then play resumes with a throw-in for the team that had control (or was entitled to the ball) from the place nearest where the ball was when play stopped. A player's technical foul counts as a team foul; a bench category 1 technical is charged to the head coach and does not.
Referees may prevent technical fouls with warnings, or overlook minor, obviously unintentional infractions with no direct effect on the game, unless the same infraction is repeated after a warning.

A disruptive foul (Art. 37) is a player's illegal contact with an opponent that does not rise to the level of a flagrant foul, and that disrupts the flow of the game and places the opponent at a disadvantage. The criteria are:
Referees must interpret disruptive fouls consistently throughout the game and judge only the action.
Penalty: charged against the offender and counted as a team foul. Free throw(s) go to the fouled player (2 if not shooting; the goal plus 1 if shooting and successful; 2 or 3 if shooting and unsuccessful), then a throw-in from the throw-in line in the team's frontcourt, opposite the scorer's table.

Since 1 October 2026 the flagrant foul (Art. 38) replaces the old unsportsmanlike foul for serious contact. It is a player's illegal contact that violates the spirit of sportsmanship and fair play and, by its nature or severity, exceeds the limits of a personal or disruptive foul. The criteria are:
Referees must interpret flagrant fouls consistently throughout the game and judge only the action.
Penalty: charged against the offender and counted as a team foul. Free throw(s) go to the fouled player (2 if not shooting; the goal plus 1 if shooting and successful; 2 or 3 if shooting and unsuccessful), then a throw-in from the throw-in line in the team's frontcourt, opposite the scorer's table.
Disqualification: a player is disqualified when charged with two flagrant fouls, two category 1 technical fouls, or one flagrant foul and one category 1 technical foul.
