The annual whale migration along Western Australia's south coast is underway and photographers and videographers are at the ready to capture footage and images of the gentle giants.
From May to October humpback, southern right, and blue whales head north to breeding and feeding grounds in warmer waters before returning to Antarctic waters.
It's the perfect time to spot the mammals from coastal locations and to send drones up to take photos.
"Marine mammals are obviously quite difficult to get to, so people are using and looking to use drones because you get greater access to the animals," marine biologist Joshua Smith said.
But there are concerns about disturbing marine life with remotely piloted aircraft (RPA) users, such as drones, if they are flown irresponsibly.
"One thing we've definitely seen over the last several years is an increase in the use of drones, for recreational users and also for commercial purposes," Dr Smith said.
"Education is paramount and getting the word out is critical, and as a member of the public, you may not necessarily know where the resources are to go to.
"But fundamentally, your state government websites are a really good start for that."
RPA users must make sure they don't interfere with or impact on marine mammals, according to the Department of Biodiversity, Conservation and Attractions.
Users must make sure a separation distance of 60 metres is maintained between the RPA and marine mammals, including whale sharks, whales, orcas, dolphins, dugongs and seals.
Before flying an RPA, the relevant district office needs to be contacted in order to ensure that the drone does not impact on, or is not impacted by, aerial and other park management operations.
Do not disturb
Responsible flying ensures whales and other marine mammals are not disturbed.
"So, reproduction, migration, resting behaviours, mating behaviours and so forth," Dr Smith said.
"It's making sure there's no disturbance to the whales when they're resting or when the mothers are calving their young, weaning their young, just basically enabling the whales to do what they need to do without being disturbed."
A study published in March by Marine Mammal Science observed the likelihood of belugas responding to a drone.
It found sudden dives increased when drone altitude decreased, particularly below an altitude of 23m.
Dives were also common when the drone first approached the whales, suggesting the devices may spook them.
The study also noted drone disturbances were rare when the drone was flown above 30m in altitude.
