Reports indicate varying levels of great white shark activity in different coastal regions. In New South Wales, Australia, warnings were issued for the Hunter and Mid North coasts due to increased shark activity. Local observations attributed this to unusually warm and fast-moving ocean currents that concentrated sharks closer to beaches between Port Macquarie and Sydney.

In the United States, researchers detected nine great white sharks approximately 100 miles off the Texas coast. These sightings, identified via tracking tags, represent a rare occurrence west of the Mississippi River, as the species has not been documented in this specific area for over 25 years. Scientists suggest these detections may indicate an expanding population in the western North Atlantic Ocean.
