Woodford Dam has mobile connectivity?

On 1st January, a pair of 23-year·old newlywed from America got lost around Woodford Dam.
They were able to call triple 0 and advised to download the Emergency+ app, which gave their exact location. Two Police Rescue Squad operators found them quickly. The pair were hot and thirsty, but uninjured, and driven back to their car.
The Emergency+ app is free and works on GPS functionality in smart phones.
