There is, I suppose, a Heraclitian aspect to our film because nothing is fixed in the outback. The petroglyphs weather and the granite grows its rinds of colorful lichen, the courses of creeks and rivers change in drought or in flood, wildfire scorches the sage and forests alike. The horses and cattle most certainly change, and so too do the people change, adapting to time and circumstance to meet the challenges of the wider cultural evolution, markets, and technology.
