It beats me that 10 people will spend a collective 15+ hours digging a ditch to move water away from the vehicle entrance so they can get their vehicles on the beach.

People with shovels digging a channel in sand.

Yet none of them ever turn out to help plant 4,000 spinifex plants. A single spinifex plant can trap 16 m3 of sand a year.

Wide view of people planting.
