Hugging the horizon, 60 kilometres off the Western Australian coast, the low-lying Abrolhos Islands are home to cray-fishing and, more recently pearl-farming families. With only minimal, low-vegetation, these islands are windswept, and tough underfoot with feet-cutting coral. Without access to mains supplies, the island dwellers use rainwater collected from their shack roofs, and power generated from solar and wind. These islands are not for the faint hearted.
