Saving loggerhead turtles: the annual sacrifice to preserve an ancient journey

Each summer for 40 years Nev and Bev McLachlan have camped on a remote Queensland beach to monitor and tag nesting sea turtles. Melissa Davey joins them on their mission

It's about 7pm at the remote Wreck Rock beach within Deepwater national park in Queensland and Nev and Bev McLachlan are starting the night watch.

For the past 40 years the husband and wife have been travelling from their home on the Sunshine Coast to a tiny campsite about 140km north of Bundaberg, their enormous caravan full of camp supplies as well as turtle tagging and monitoring gear.
