Scientists report that two humpback whales travel between breeding grounds in eastern Australia (including Queensland) and Brazil, crossing large areas of open ocean. Multiple outlets say researchers used a mix of observations and photo-based verification to track movements between sightings. ABC Australia and Phys.org describe analysis of a database of photos and fluke identification, documenting trips from Queensland to Brazil covering about 14,200 km, and open-ocean crossings of more than 14,000 km between the two regions. ScienceDaily adds that at least one individual whale covers a record distance between sightings, citing a journey of at least 15,100 km. The Guardian describes a whale first photographed off Brazil in 2003 and later spotted off north-east Australia in September 2025, giving a distance estimate of about 15,100 km (reported as roughly 15,000 km by some outlets). Deutsche Welle similarly characterizes the route as the longest lifetime journey on record for the species. Overall, the sources agree the findings establish the longest confirmed migration distances between verified sightings of individual humpback whales.
