Horses •
Thowra (voiced by John Higginson (Season 1) and
Brett Climo (Seasons 2 and 3)) is the "Silver Brumby", and Yarraman's youngest son. He is calm, kind and brave horse who values his friends. He is often chased by the Man. •
Storm (voiced by Doug Tremlett) is an older brother of Thowra. He is a loyal and kind horse who stands by Thowra's side in the event of trouble. Starting in Season 2, it is presumed that Storm left Thowra's gang to form his own herd, as he is only mentioned and never seen again. •
Arrow (voiced by
Rhys Muldoon (Season 1) and
Stephen Whittaker (Seasons 2 and 3)) is a chestnut brumby and half-brother of Thowra, and one of the oldest of Yarraman's three sons. Arrow is an arrogant and jealous horse who seeks an opportunity to prove himself better than Thowra, but often gets himself into trouble. Occasionally he will assist Thowra when trouble affects him too. He gets his name from the arrow-shaped marking on his face. It is presumed that Arrow inherited his mean-spirited nature from his mother. According to Benni, there was 'never a mean-spirited mare like her'. •
Boon Boon (voiced by
Rebecca Gibney (Season 1) and
Marg Downey (Seasons 2 and 3)) is a pretty filly and the
Brolga's daughter, who loves Thowra and is his equal on courage, compassion and wisdom. •
Brolga (voiced by
John Stanton) is a bitter, pompous and bossy stallion who fiercely protects his herd and does not welcome Thowra or his friends. He fought Yarraman, Thowra's father, and slew him, claiming the title "King of the Cascade Brumbies" in the process. •
Aranda (voiced by Marg Downey) is a paint-colored horse and the Brolga's favourite mare. She often watches the herd while the Brolga is away. •
Yooralla is a young
foal who joins Thowra's herd. He became lost from his mother and home herd after a storm. His older sister, Gunda, came to take him home, but he decided to stay with Thowra to continue learning the ways of the wild. •
Yarraman is Thowra, Storm and Arrow's father, former "King of the Cascade Brumbies". His mate was Bel Bel. Eventually the Brolga succeeded him. •
Golden (voiced by Robyn Gibbles (Season 1) and Abbe Holmes (Season 2 and 3)) is a
palomino filly, brought to the bush by the Man. She is briefly freed by Thowra, but decides to return home after she is injured by a razorback. She escapes later on after hearing rumours of Thowra's leap to death, then returned to the Man after proving the rumours were false. •
Ebony is the black race horse, who visits the High Country to have a race to beat Thowra. •
Gunda is a young filly and Yooralla's older sister. She came to the High Country to find her brother after he was lost during a storm. After hearing of his decision to stay, she returns to her home herd in the South. •
Narrabri is a young foal in Thowra's herd. He and Yooralla are good friends, and spend time playing together, but they have a tendency to get into trouble while playing. Narrabri is quite a level-headed youngster, as he realizes that they are in trouble before Yooralla, and remembers old advice/sayings during times of trouble. Narrabri and Yooralla are some of the first to encounter the Bun-Yip at Misty Lake. •
Yuri is one of The Brolga's sons. Yuri is a friend of Yooralla's, and sometimes leaves his herd to play with the orphan foal. He doesn't think much of Thowra, having been brought up to think The Silver Brumby is less than his legend. He too gets into trouble while playing with Yooralla. •
The Prince of the West is a narcissistic and foolish stranger from the West, who comes to the High Country in search of a mate to take back with him. While Thowra is away, and Arrow is left in charge of the herd, he sets his sights on Boon Boon but is unlikely to win The Brolga's approval. He returns home to the West after the Brolga chases him off. •
Boomerang is a young foal from Thowra's gang, and is the only one of the three colts in the gang that escape the capture of the Man. •
Ilinga is an elderly brumby from the South who comes to the High Country in search of Thowra to see if the legends she has heard are true. She wishes to see what Thowra is like and determine if he will make a good King of the Cascade Brumbies. •
Bel Bel is Thowra's mother and former mate of Yarraman. She is seen in the opening credits, and appears to have similar coloring to Thowra and Golden. •
Rocky and Woomera are two colts from Thowra's herd who foolishly follow Arrow when fleeing from a brumby hunt. As a result, they are captured, and become too used to the food given to them by The Man to want to return to the wild. •
Anda is one of the Brolga's daughters. Anda and Moolie caused Aranda to fall over a cliff one day when running away after a snake scare. They go to fetch help to free Aranda. •
Moolie is one of The Brolga's sons. He doeasn't have much luck with snakes, often finding himself a target of them. He and Anda almost cause Aranda a trouble while bolting from a snake. •
Echo is the Man's black horse, who has chased Thowra all over the High Country. It is clear that he respects Thowra in the way he speaks of him. He is loyal to The Man, and is renowned as the strongest, fastest stock horse in the district. •
Snowy is Charlie's white horse.

Whip Bird is to Thowra what Currawong is to Brolga. The small green bird comes to tell Thowra what she has heard if it is something of consequence.

circus who was lost because the transport crashed in a storm, and was forced to hunt the local fauna until Thowra tricked him into a pit trap.

He gains a new appreciation for Thowra and Boon-Boon after they free him from an avalanche. •
