'Unfinished business' lures couple back to Queensland island paradise

Key points

• Louise Collier and Steve Sharpe have returned to Low Isles, off Port Douglas, to begin a second stint as live-in caretakers on the Great Barrier Reef. They first took the role in 2003 and stayed until December 2008.
• Their son Tom was born on the island in 2005 and spent his first four years there. The couple say a modern solar system and satellite internet have changed daily life on the island.
• They are hopeful the new stint could last four years.
