Is this giant sushi or the cotton harvest?
This was an irrigated area, probably, around the Macquarie River, central NSW  The river had not dried up.

• When mature, the crop is harvested mechanically and placed into large modules. The modules are loaded onto trucks and transported from the farm to a cotton gin (short for en-gin). Cotton gins are factories that separate cottonseed and trash from the lint (raw cotton fibre)
• The cotton lint is tightly pressed into bales. An Australian cotton bale weighs 227kg (500 pounds)
• Once the cotton bales are ginned, pressed and containerised, they are loaded on to trucks and trains and sent to port for shipping, mostly to overseas markets.
