Consists of a technical routine, lasting between 4 minutes 45 seconds and 5 minutes 15 seconds. The technical routine accounts for 35 percent of the total score, the free routine for 65 percent. Routines are scored by seven judges on a scale of 0 to 10.0. Each judge scores a routine for technical merit and artistic impression. The technical merit score os derived by weighing execution of strokes and figures, synchronisation within the team and with the music, and difficulty of strokes and figures. The artistic impression score weighs choreography with music interpretation and manner of presentation. The final score for each routine is determined by dropping the highest and lowest score for both technical merit and artistic impression, dividing by five and then multiplying it by six for technical merit and four for artistic impression.

Figures range from simple moves like the somersault back tuck to difficult moves such as the Eiffel Tower combined spin. Synchronised swimming has a reputation as a somewhat sill sport, but in fact it is more physically demanding than many other sporting endeavours, such as shooting, dressage or playing right field in a baseball game.

Synchronised swimming was introduced as an Olympic sport in 1984. It will be held in the Sydney International Aquatic Centre, located in Sydney Olympic Park.

Water polo is played with 7 men on a team including a goal keeper. Matches consist of 7 minute quarters. Ties are not broken in the preliminary round. In the medal round, if here is a tie after regulation play, play continues with two, three minute overtime periods. If the score is still even, additional three minute periods are played. The matches end as soon as a goal is scored. A goal is scored when the entire ball passes over the goal line, between e goal posts, and underneath the crossbar. A goal may be scored using any part of the body except for q clenched fist. As in basketball, there is a shot clock: each team must take a shot at the goal within 35seconds of taking possession of the ball. If they fail to do so, the opposing team takes possession.

The field play in water polo is 30m from goal lone to goal line. The goal posts are 3m apart; the underside of the crossbar is 90cm above the surface of the water. The water must be at least 1.8m deep and preferably 2m deep. The water temperature must be between 25 and 27 degrees Centigrade.

An offside rule is enforced: no offensive player may cross the line 2m in front of the goa unless he is preceded by the ball.

Water polo is a rough sport filled with a variety of fouls and accompanying officials' whistles. Ordinary fouls include holding on to the goal posts, holding the entire ball under water, hitting the ball with a clenched fist, touching the ball with both hands at the same time, impeding the free movement of another opponent who is not holding the ball, pushing an opponent, and wasting time. An ordinary foul is punished by awarding the opposing team a free throw from the point of the foul. If a foul is committed by a defending player within the 2m area, the free throw is taken from the 2m line.

Exclusion fouls include interfering with a free throw, intentionally splashing water in an opponent's face, holding an opponent, kicking or striking an opponent, using foul language, showing disrespect to the referee or other official, and committing an act of brutality. Exclusion fouls are punished by the awarding of a free throw and by the exclusion of the guilty player from the match for 20 seconds or until a goal is scored or his own team regain possession.

Penalty fouls include committing a foul within 4m of the goal a player is defending, if a referee rules that the foul prevented a probable goal, committing an act of brutality within 4m of the goal, and toppling the goal cage to prevent a probable score. A penalty throw is taken from behind the 4m line and any player on a team may be chosen to take the shot. If a penalty throw rebounds off the goal or the goal keeper, it is considered in play and the match continues.

Water polo was introduced to the Olympics in 1900. It will be held in the Sydney International Aquatic Centre and the Ryde Aquatic Leisure Centre. These places can be located in Sydney Olympic Park and Sydney's West.

This event is performed from a springboard 3m above the water. The easiest dive, with a coefficient of 1.4, is a simple forward dive in the tuck position. The most difficult, with a coefficient of 3.6, is the back 1 1 / 2 somersault with 4 1 / 2 twists free. The scores of the seven judges are multiplied by a coefficient that is determined by the degree of difficulty of the attempted dive. Olympic competitions begin with a preliminary round. Between 1968 and 1992 the top 12 dives then advanced to the final, which in 1992 consisted of 11 dices ¡V five required and six voluntary. In 1996 a new system was introduced. The top 18 divers in the preliminary will advance to a semifinal. The top 12 semi finalists will go on to the final. Scores in the semifinal will be added to scores in the final to determine the winners. The semifinal in the men's springboard will comprise of five divers with a total degree of difficulty not to exceed 9.5. The final will comprise six dives with unlimited degree of difficulty.

This event is staged from a rigid platform 10m above the water. In 1996 the semifinalists will perform 4 dives with a total degree of difficulty not to exceed 7.6. The finalists will perform six dives unlimited degree of difficulty.
