Brumbies were the cover stars, and feature story, in the Jan/Feb issue of Australian Geographic (and many thanks to my cousin for tipping me off to that fact!). The piece begins with a good news story from an Aboriginal community in Central Australia, where training for the Certificate II in rural operations (in which horses play an integral role) has reignited interest in education, and offers hope of employment opportunities for community members. 
While the article does by and large present an even-handed account of the brumby debate, we still find that oft-repeated assertion that ‘horses are deeply embedded in [Australia’s] psyche’ , without any further exploration of why that might be (the obligatory mentions of The Silver Brumby and Banjo Paterson aside).
We do, however, learn that Australia’s wild/feral (pick your adjective of choice; the article acknowledges the dichotomy, but sticks with ‘wild’) horse population is now estimated to be ‘at least’ one million animals!  This is a significant increase from previous figures I’ve encountered, where numbers were postulated at around the 400,000 mark. If those figures were correct when the research was published in 2007, then this population increase is nothing short of remarkable. Yet given that brumbies are able to increase their population by up to 20% in a good year,  and given that there have been no real bad years in the past decade, this figure is actually not surprising.
Central Australia apparently has a healthy brumby population, and several Aboriginal communities are now looking at ways to exploit this resource, including mustering horses for sale.  The versatility of the brumby as a breed is emphasised in the article, and Erica Jessup, founder of the Guy Fawkes Heritage Horse Association, is quoted as saying that owning a brumby has ‘become very fashionable.' But can you rehome a million of them?
There is a limit to how many horses Australians can adopt. Especially when brumbies are not the only horses seeking second chances. In a piece of blue-sky thinking produced by the Rural Industries Research and Development Corporation in 2001, it was argued that all racehorses exiting the racing industry could successfully be rehomed, and that the demand for off the track thoroughbreds ‘will most likely increase over time as people shift from using other breeds and instead use thoroughbreds.' There are also standardbreds (trotters and pacers) looking for homes after racing.
A horse is not as easy to rehome as cat or dog (and there are thousands of those looking for ‘forever’ homes across our nation’s pounds and animal shelters). A horse requires very specific, and expensive, care, including specialised feeding, dentistry, and hoof care. If something goes wrong, a horse needs attention from a qualified veterinarian. It requires a large amount of space to live comfortably. Finally, a horse’s owner or handler requires specialist skills to care for that animal correctly. It’s not as simple as feeding it twice a day and leaving it in your backyard while you’re at school or work. For this reason, well-meaning people looking to re-home brumbies or ex-racers who do not have the skills to care for these animals ultimately do them a grave disservice.
In the case of the brumby, if population control is required (and the Australian Geographic piece acknowledges that it does), then lethal control methods (ie shooting or otherwise euthanasing) are the most humane and effective solution. Today, the majority of brumbies caught by passive trapping (the current crowd-pleasing ‘control’ method of choice) are not rehomed, but end up being trucked hundreds or thousands of kilometres, and meeting an unpleasant fate at an abattoir.
To insist that horses not be shot in national parks, but then to do nothing when the approved method of managing brumby populations, implemented due to people’s squeamishness at the idea of wild horses being shot, means that these same horses must go through the trauma of being captured, wrested from the only homes they’ve known, and finally butchered at a knackery, ultimately reeks of animal cruelty.
