What are the 5 most common tick species found in Australia?


Before jumping into Nexgard Spectra, did you know that there are over 70 species of ticks found in Australia? Some of the more well-known tick species are below, which are the most well known Aussie ticks for posing health risks to humans and animals, as they can transmit deadly diseases.

That's why it's so important to take precautions and be vigilant wit tick prevention in your dog, and why millions of Aussie use Nexgard Spectra. Here's the 5 most common Australian tick species:

  1. Paralysis ticks (Ixodes holocyclus): These are one of the most medically important tick species in Australia. They can cause paralysis in dogs and transmit a disease known as tick paralysis. These ticks are commonly found along the eastern coast of Australia.

  2. Brown dog tick (Rhipicephalus sanguineus): This tick primarily infects dogs and is found in various parts of Australia particularly Northern and inland areas where they thrive in our warmer climate. They can transmit diseases and cause skin irritations in dogs.

  3. Cattle tick (Rhipicephalus (Boophilus) microplus): As the name suggests, this tick primarily infests cattle but can also affect other livestock animals. It can transmit diseases and is economically significant in the livestock industry.

  4. Kangaroo tick (Amblyomma triguttatum): These ticks often infest kangaroos and wallabies but can also attach to other animals and even humans. They are widespread throughout Australia and can transmit diseases.

  5. Bird ticks: Various tick species are associated with birds in Australia. These ticks can sometimes infest domestic poultry and may pose a threat to both birds and their handlers.


It's important to note that some of these ticks can transmit diseases to both animals and humans. Tick-borne illnesses can range from mild to severe, so it's essential to be aware of tick prevention and how to safely remove ticks if you or your pets come into contact with them.


How do ticks get onto your dog and into your home?



In Australia, ticks can get onto your dog through various ways, and deadly paralysis ticks are now found not only across the East Coast of Australia, but also as far south as Tassie. 

Here are where ticks live, and where they are most likely to get onto your dog’s coat:

  • Vegetation: Ticks often reside in tall grass, bushes, and wooded areas. When your dog walks or plays in these environments, ticks can easily climb onto their fur and attach themselves.

  • Contact with Infested Animals: If your dog comes into contact with other animals, such as wildlife or other dogs, that are carrying ticks, these ticks may transfer onto your dog's fur.

  • Outdoor Environments: Ticks can be present in your backyard, especially if it has tall grass or wooded areas. Dogs spending time in their own yard can pick up ticks in this manner.

  • Hiking and Walking Trails: When you take your dog hiking or for walks in areas where ticks are prevalent, they can pick up ticks from the environment.

  • Interactions with Wildlife: Encounters with wildlife like scrub turkeys, snakes, or rodents can lead to tick infestations. These animals can carry ticks, and if your dog chases or interacts with them these ticks may transfer to your dog.

  • Transfer from Humans: While less common, ticks can also transfer from humans to dogs. If a person unknowingly carries ticks and has close contact with the dog, the ticks may transfer onto the dog's fur.


It's important to regularly check your dog for ticks, especially after outdoor activities in tick-prone areas. Prompt removal of ticks is essential to reduce the risk of tick-borne diseases. Additionally, the use of tick prevention like Nexgard Spectra is vital for tick prevention, especially deadly paralysis ticks.
