Flying with your dog within Australia: domestic airline policies, breed restrictions and cabin vs cargo

Flying with a dog within Australia is simpler than flying internationally — there are no import permits, no quarantine facilities, and no titer tests. Dogs move freely between Australian states and territories without any biosecurity permit requirements. But "simpler" does not mean uncomplicated. Australian domestic airlines have widely varying policies, breed restrictions that catch flat-faced dog owners off guard, and seasonal temperature embargoes that can ground a pet booking with very little notice. This guide covers everything Sydney-based dog owners need to know before booking domestic air travel for their pet.

The Australian domestic airline landscape for pets

Australia's domestic aviation market is dominated by three main operators: Qantas, Virgin Australia, and Rex Airlines (Regional Express), with Jetstar and Bonza (to the extent Bonza continues to operate) serving budget leisure routes. Their pet policies differ significantly — to the point where the answer to "can my dog fly?" depends entirely on which airline you are using and which route you are flying.

Qantas: cargo only, no cabin pets

Qantas does not accept pets in the passenger cabin on any of its domestic or international routes. All pets travel as freight through Qantas Freight's dedicated pet service, branded as PetsOnBoard (for domestic flights managed through the Qantas Freight network). This is a cargo booking, separate from your passenger booking — pets travel in the aircraft's pressurised, temperature-controlled freight hold, but the booking is made through Qantas Freight, not through the passenger booking system.

On most Qantas domestic routes, including Sydney–Melbourne, Sydney–Brisbane, Sydney–Adelaide, and Sydney–Perth, pets can travel as freight cargo. However, not all routes are available for live animals — some regional routes or specific aircraft types may not accept live animal cargo. Confirm availability for your specific route when booking.

• No in-cabin pets on Qantas: applies to domestic and international routes
• All pets travel via Qantas Freight (cargo division) — book through qantasfreight.com or Qantas Freight offices
• Dogs in the freight hold travel in the lower-deck cargo area of passenger aircraft, which is pressurised and temperature-controlled
• IATA-compliant crate required (CR82 standard)
• Temperature embargoes apply: Qantas Freight suspends live animal cargo when forecast temperatures at origin or destination airports are forecast to exceed thresholds (typically around 29–30°C on the ground) — applicable during Sydney's summer months (December–February) in particular
• Brachycephalic breed restrictions apply to Qantas Freight domestic pet services — see the breed restriction section below
• Weight and size limits apply: confirm current limits with Qantas Freight for your dog's size
• Confirm current policy, fees, and availability at qantasfreight.com or contact Qantas Freight directly

Virgin Australia: small dogs in the cabin on some domestic routes

Virgin Australia is the only major Australian domestic carrier that currently permits small pets to travel in the passenger cabin, under the seat in front of the owner, on eligible domestic routes. This is a meaningful distinction for owners of small-breed dogs — cabin travel is generally lower-stress than cargo, and the dog remains with the owner throughout the journey.

However, Virgin's in-cabin pet policy comes with significant eligibility constraints. Not all routes are eligible; not all aircraft types are configured for in-cabin pets; the combined weight of dog plus carrier is capped at 10 kg; and the carrier must fit under the seat (Virgin specifies maximum carrier dimensions). Advance booking is required — the number of in-cabin pet spaces per flight is limited, and they fill quickly on popular routes.

• Small dogs and cats permitted in-cabin on eligible Virgin Australia domestic routes
• Combined weight limit: 10 kg total (dog plus carrier) — check this is achievable for your dog before booking
• Carrier must be soft-sided and fit under the seat in front of you — check Virgin's current maximum carrier dimensions at virginaustralia.com before purchasing a carrier
• Advance booking required: book through Virgin Australia; availability is limited per flight
• Not all routes eligible: primarily the main East Coast trunk routes (Sydney–Melbourne, Sydney–Brisbane, Melbourne–Brisbane); regional and codeshare flights may not be eligible
• Not all aircraft types are eligible: confirm the aircraft type for your specific flight
• Brachycephalic breeds: Virgin Australia's in-cabin policy has specific conditions for brachycephalic breeds — they may be accepted in-cabin given the shorter exposure time and owner supervision, but confirm the current policy with Virgin directly for your specific breed
• Virgin also offers a cargo pet service for dogs that do not meet in-cabin requirements — confirm current availability
• Confirm current policy, fees, eligible routes, and carrier dimensions at virginaustralia.com or by calling Virgin's customer service

Rex Airlines and regional carriers

Rex Airlines (Regional Express) operates domestic services across Australia, including regional routes not served by the major carriers. Rex's pet policy has evolved over time. As of mid-2026, Rex generally accepts small pets in the cabin on some services, but policy can vary by route and aircraft type. Regional aircraft (including propeller and turboprop aircraft used on regional routes) may have different pet policies from jet services. Always confirm directly with Rex (rex.com.au) for your specific route before booking.

Budget and ultra-low-cost carriers, including Jetstar, generally do not accept pets on domestic services (other than NDIS/disability assistance animals, which are managed under separate rules). Do not assume a budget carrier accepts pets without confirming first — the answer on most budget domestic routes in Australia is no.

Brachycephalic breed restrictions on Australian airlines

Brachycephalic (flat-faced) dog breeds present elevated respiratory risk during air travel due to their anatomically compromised airways. Under the stress of travel, confinement, heat, and the reduced oxygen availability at altitude, dogs with brachycephalic obstructive airway syndrome (BOAS) can deteriorate rapidly. Both Qantas Freight and Virgin Australia apply breed-specific restrictions as a result, and these are among the most frequently misunderstood aspects of domestic pet air travel in Australia.

• French Bulldog: restricted or prohibited from hold/cargo travel on most Australian airlines; the most common brachycephalic breed appearing in pet air-travel refusals in Australia
• English Bulldog (British Bulldog): restricted or prohibited from hold/cargo travel
• American Bulldog: restricted or prohibited
• Pug: restricted or prohibited from hold/cargo travel on most carriers
• Boston Terrier: restricted on many carriers
• Boxer: restricted on many carriers
• Shih Tzu: may be restricted depending on carrier and individual assessment
• Pekingese: typically restricted
• Lhasa Apso: typically restricted
• Cavalier King Charles Spaniel: some carriers apply restrictions; others permit with conditions
• Brussels Griffon, Affenpinscher, Japanese Chin: typically restricted
• Note: breed lists are not standardised across airlines — each carrier maintains its own list, and lists are updated periodically. Always confirm the current restricted-breed list with your specific carrier for each booking.

Cargo vs cabin: what is the real difference?

The main practical differences between cargo and cabin travel for dogs are stress levels, visibility, and owner presence. In the passenger cabin (Virgin Australia, on eligible routes), a small dog travels in a carrier under the seat, can hear and smell the owner, and benefits from the relatively stable environment of the passenger cabin. Research on animal welfare during air transport generally suggests that in-cabin travel — where permitted and where the animal fits comfortably — produces lower stress responses than hold/cargo travel, primarily because of proximity to the owner.

In the hold or cargo, the dog is in a pressurised and temperature-controlled environment, but is separated from the owner and subject to the noise and movement of the cargo area during loading and unloading. Modern wide-body aircraft holds are well-managed for temperature, but the loading and unloading phase — when the crate is on the tarmac or being handled by freight staff — is when temperature exposure and stress are highest. This is why temperature embargoes focus on ground-handling conditions, not in-flight conditions.

For dogs that are too large or heavy for in-cabin travel, cargo is the only option, and it is safe for most dogs on most Australian domestic routes with a compliant crate and appropriate preparation. The welfare risks in cargo arise when temperature embargoes are ignored, when crates are non-compliant, or when brachycephalic breeds travel in conditions that exacerbate their breathing difficulties.

IATA CR82 crate requirements: what you need

Any dog travelling in the cargo hold of an Australian domestic flight must be in an IATA Container Requirement 82 (CR82) compliant crate. A non-compliant crate will be refused at cargo check-in. The CR82 standard specifies that the crate must be rigid and escape-proof, the dog must be able to stand at full natural height without touching the roof, turn around completely, and lie down in a natural position.

• Measure your dog standing naturally: height from floor to the top of the head or ears, whichever is taller; add at least 7–10 cm for minimum internal crate height
• Length: measure from tip of nose to base of tail in natural standing posture; add 7–10 cm for minimum internal crate length
• Width: sufficient for the dog to turn around without its nose touching the side walls
• Construction: rigid, hard plastic or fibreglass only — soft-sided carriers are not CR82 compliant for hold travel
• Door: metal door with metal fasteners; plastic clip-only closures do not meet the standard for most carriers
• Ventilation: on at least three sides; many crate models have ventilation on all four sides
• Floor: solid, leak-proof base with adequate absorbent bedding (a familiar-smelling item reduces anxiety)
• Water and food access: spill-proof bowls accessible from outside the crate without opening the door
• "LIVE ANIMAL" labels and directional arrows affixed to the crate correctly
• Owner contact details attached to the exterior of the crate

Temperature embargoes: when your booking can be cancelled

Australian domestic airlines impose live-animal embargoes when forecast temperatures at any point on the journey are expected to exceed defined thresholds during the ground-handling phase. These thresholds are designed to protect animals from heat stress during the time the crate is on the tarmac — before loading or after unloading — when exposure to radiant heat from the runway surface can rapidly push temperatures inside a crate to dangerous levels.

For Qantas Freight, the live-animal embargo threshold is typically around 29–30°C at any point on the route. When a forecast breaches this threshold for the estimated ground-handling window at origin or destination, Qantas Freight will not accept the booking — even if you have an existing confirmed booking. This is not a compensation event under Australian Consumer Law for safety-related policy decisions. You should not plan a dog's travel on routes where summer temperatures are consistently high without a backup plan.

In Sydney, maximum summer temperatures (December through February) regularly exceed 30°C. On days where the forecast exceeds the embargo threshold, same-day cancellation of live-animal cargo bookings can happen. Sydney-to-Perth routes in summer can face embargoes at both ends simultaneously (Perth also has hot summers). The practical advice is to schedule domestic pet air travel in the cooler months where possible — May through September is generally lower-risk for temperature embargoes from Sydney.

• Qantas Freight embargo threshold: typically around 29–30°C at origin or destination — verify current threshold with Qantas Freight for your booking
• Virgin Australia: similar temperature policies apply; confirm for your specific route
• Most high-risk period from Sydney: December, January, February — peak summer
• Lower-risk period: May through September — cooler months generally present fewer embargo risks on most Sydney domestic routes
• Always have a backup plan: if your travel date falls in summer, consider whether road transport or rail freight is a viable alternative for your dog
• Check the forecast within 48 hours of travel: embargoes are based on forecast temperatures, which are only reliable close to the travel date

No health certificate required for domestic travel

A health certificate from a veterinarian is not required for domestic air travel within Australia. Unlike international travel, there are no state biosecurity entry requirements for dogs moving between Australian states and territories (dogs are not subject to the same livestock movement controls). You do not need a permit or health certificate to take your dog from Sydney to Melbourne, Brisbane, or Perth by air.

However, it is always a good idea to ensure your dog's core vaccinations are current before any travel, and to have a copy of your dog's vaccination records accessible in case it is needed. Some boarding facilities at the destination may request vaccination evidence if you use pet boarding before or after your flight. If your dog has a health condition that could be exacerbated by the stress of air travel, discuss fitness to fly with your vet before booking.

Practical advice: booking and day-of-travel

• Book the pet cargo or in-cabin space at the same time as your own ticket — do not leave it until later; spaces are limited and frequently fill before the flight
• Confirm in writing: get a booking reference number specifically for the pet booking, separate from your passenger booking reference
• Purchase and test your crate well before travel day: put the dog in it with the door closed for increasing periods over 2–4 weeks; a crate-comfortable dog travels more calmly
• Do not sedate: the AVMA (American Veterinary Medical Association) and most veterinary authorities advise against sedating dogs for air travel; sedation impairs balance and respiratory function, which increases injury risk in cargo and respiratory risk for brachycephalic breeds — discuss any anxiety management with your vet before travel using evidence-based, non-sedative options
• Withhold food for 4–6 hours before travel to reduce nausea risk; ensure access to water before crating
• Exercise your dog well the morning of travel to help them rest in the crate
• Arrive early at the cargo terminal (or passenger terminal for in-cabin) — cargo check-in processes take longer than passenger check-in; allow at least 2–3 hours
• Check the weather forecast for both origin and destination in the 48 hours before travel, particularly in summer, so that an embargo does not come as a surprise
• Attach your contact details to the crate and carry all relevant documentation (booking reference, vaccination records) with you
