Dorothea Mackellar, author of poem My Country, immortalised on giant silo artwork

When Dorothea Mackellar penned My Country, the wide brown land was almost unfailingly white, with many Australians, including their government, much preferring it that way.

Now, well over a century later, in an expression of Australia's evolution as a nation, the task of immortalising Mackellar in the town where she spent much of her youth has fallen to Heesco Khosnaran, a Melbourne-based Australian street artist with Mongolian heritage.

On the concrete blank canvas of the historic Gunnedah Maize Mill, Mr Khosnaran recently completed a silo art mural - now one of as many as 44 (and ever-growing) scattered around regional Australia - variously depicting Mackellar in her youth, a local horse-drawn harvesting scene and an extract of the most well-known stanza from the poem.

"My work takes me to many different parts of Australia and with each place I learn more about Australian history and culture and it is always very interesting to me," says Mr Khosnaran. "I've spent pretty much all my adult life in Australia. It gave me this life and career. I'm more than happy to give back what I can.

"[Similarly to My Country], there is a very famous [Mongolian] poem called My Native Land by Natsagdorj .We all learned it in primary school. The poem's been made into a song and is constantly referred to in Mongolian culture but I don't think I've seen a mural dedicated to it. I would love to paint a mural dedicated to it, for sure."

Philippa Murray, chair of the Dorothea Mackellar Memorial Society in Gunnedah - a town of almost 13,000 located in north-eastern NSW - is the instigator of the mural as well as poetry awards in the poet and author's name.

Ms Murray reckons that the My Country poet, who died in 1967, would be "rapt" by the chosen artist and the mural she considers to be emblematic of "the circle of life of old and new Australia".
