Damir Dokic could face up to eight years in prison if found guilty of "endangering the security'' of the ambassador and unlawful possession of weapons.
Dokic appeared calm as he arrived under police escort at the court in Ruma, a town about 50 kilometers (30 miles) northwest of Belgrade.
He was arrested earlier this month after reportedly saying he would blow up ambassador Clair Birgin's car if she didn't stop negative articles about him from being published in Australia. Jelena Dokic had given interviews to Australian media, saying her father had beaten her.
Dokic had told Serbian media he would fire a rocket launcher at Birgin's car, but later said the statements were made in anger. He also has admitted having beaten his daughter.
Jelena Dokic, born in the former Yugoslavia, migrated to Australia with her family as a child and represented her adopted country at the 2000 Olympics. She renounced her Australian ties in 2001 to move back to Serbia, then decided to compete for Australia again in 2006.
The 26-year-old Dokic is ranked No. 72. She retired from a second-round match at the French Open while leading against fourth-seeded Elena Dementieva after twisting her back.
