An electronic barrier malfunction | Sydney Harbour Force 2/10

Two stranded fishermen hang on for their lives as their boat sinks beneath them kilometres out to sea and in shark infested waters. It’s a job for the rescue helicopter to save them with only moment to spare before their boat sinks to the bottom of the ocean. In the middle of the harbour, a research team lay baits to tag the infamous Bull sharks that call Sydney Harbour home, what they catch shocks everyone. A local dive team must also replace a weathered shark net and up on the Harbour Bridge its peak hour and an electronic barrier malfunction and broken-down truck threaten to bring traffic on the bridge to a standstill.
