Whale-shark sightings at Ningaloo Marine Park are most reliable from March to July. Tours are run by operators licensed by Western Australia’s Department of Biodiversity, Conservation and Attractions (DBCA); crews help locate sharks and manage the swim.
Follow the distance and conduct rules in the water. Swimming ability and age requirements vary by operator, so check the conditions before booking.
When to see whale sharks at Ningaloo
DBCA identifies March to July as the most reliable period for whale-shark sightings. Its visitor information describes March to August as the best time for the migration, and sharks sometimes remain into September or October. These seasonal periods indicate when sightings are most likely, but they do not guarantee sightings on any particular date.
Some operators run tours beyond the months when sightings are most reliable. Tours may run beyond the reliable sighting season, and a booking during those months still does not guarantee a whale shark sighting. Check the operator’s current schedule and its terms for missed sightings, repeat trips or refunds before you book.
How Ningaloo whale-shark tours work
A whale-shark tour is a managed encounter at sea rather than a swim from a fixed beach. Operators commonly use a spotter aircraft to search for sharks and guide the vessel to one. Crew brief passengers, organise entry to the water and guide swimmers during the encounter. Some tours also include snorkelling on the reef. Itineraries and equipment vary.
Commercial whale-shark tours must be conducted by operators licensed by DBCA. Book with a licensed operator and follow the crew’s instructions. A sighting is not guaranteed; whale sharks move through the area seasonally.
Age and swimming requirements
DBCA sets rules for encounters, while individual operators set their own participant requirements. There is no single age or swimming-ability rule that applies to every tour.
For example, Ningaloo Discovery says swimmers need a basic level of swimming ability and that children under 18 must be accompanied by a swimming adult. Its conditions also require an adult in the water with each child under 12 during an interaction. Ningaloo Whaleshark Swim asks participants to swim independently in open water; its published guidance says children under six are usually not permitted to swim unless a parent can vouch for their ability. These are provider-specific policies, not park-wide rules.
Before booking, check the chosen operator’s current age limits, child-supervision conditions and swimming requirements. Ask whether flotation aids, in-water guides or an observer ticket are available if you need them. Crew can refuse a swimmer entry on safety grounds or because of conditions.
Whale-shark swim rules
Keep at least 3 metres from a whale shark’s head and body, and 4 metres from its tail. Do not touch or ride the shark, or restrict its movement. DBCA’s current online guidance limits the swim to 10 people in the water at one time. Flash photography is prohibited. The rules also prohibit cameras on extension poles and motorised propulsion aids.
DBCA also controls vessel approaches. Within the 250-metre approach zone around a shark, a vessel must stay at least 30 metres away. Only one vessel may operate in that zone at a time, for up to 90 minutes and at six knots or less. Other vessels must remain farther away under the department’s rules.
