The Australian wild horse is called a Brumby. Read more here.
The great Australian film, "The Man from Snowy River", was made in 1982, based on the famous poem of the same name by A.B. 'Banjo' Paterson, first published in 1890. Kirk Douglas was lured to Australia to play the part of twins, "Harrison", the owner of a large cattle station and "Spur", a prospector.
Following are the opening lines of the poem and then a clip from the movie, famously called "The Descent" and you'll see why. The movie was filmed at Merrijig in the High Country, less than an hour (as the crow flies), from where we live and will give you an insight into the spectacular countryside around here. The main character, played by Tom Burlinson, is seen throughout and at the end of the clip cracking the whip. Tom is also a singer and sounds very much like Frank Sinatra. I hope the clip works for you; it's a bit furry but worth watching to the end and in full screen.
There was movement at the station
for the word had passed around
That the colt from Old Regret had got away,
And had joined the wild bush horses...he was worth a thousand pound,
So all the cracks had gathered to the fray.
