Australia has a unique landscape and ecosystem, and the country has strict laws and regulations to protect its environment and essential food crops. There are several plants that are illegal to grow or sell in Australia, with some differences in legislation between states. These plants are often prohibited due to their invasive nature or potential to cause harm to native wildlife and agriculture. Some examples include fountain grass, gazania, and cactus, which can spread quickly and negatively impact the local environment. Other plants may be restricted due to potential diseases, such as Myrtaceae plants, which can carry Myrtle Rust, or citrus plants in Queensland, which can carry Blueberry Rust. The movement of plants across state borders is also controlled to prevent the spread of diseases and pests.

What You'll Learn
Some plants are prohibited from being sold as food
Australia has strict biosecurity measures in place to protect its essential food crops and native biodiversity. As a result, some plants are prohibited from being sold as food or imported into the country. The Australia New Zealand Food Authority has listed prohibited plants and fungi in Schedule 23 of the Australia New Zealand Food Standards Code. Any part, derivative, or substance derived from a plant or fungus listed in Schedule 23 is prohibited from being sold as food in Australia, except with express permissions outlined in the Code. For example, the Code permits low-THC Cannabis sativa seed and seed products, as well as coca bush, but prohibits the Areca catechu nut, or betel nut.
In addition to federal restrictions, individual states and territories have their own quarantine restrictions for certain plant species. For instance, citrus plants, such as lemon, lime, orange, and kumquat, cannot be moved across state borders into Queensland. Similarly, due to the risk of a disease called Myrtle Rust, nurseries are restricted by law from moving Myrtaceae plants across state borders. This has particularly impacted the ability to send certain plant families to Tasmania and Western Australia, which already have additional high biosecurity restrictions.
Some plants are prohibited from being sold or traded within specific states or territories of Australia due to their invasive nature and potential environmental impact. For example, fountain grass, a popular landscaping plant, is a declared plant in South Australia and is not allowed to be sold or traded. This is because it produces a large number of seeds that spread easily, outcompeting native species, and it burns at high temperatures, increasing the risk of fire damage. Similarly, Gazania, a colourful ground cover native to South Africa, is banned from sale in South Australia as it competes with native species and agricultural crops. However, some sterile cultivars of Gazania are available, including 'Double Gold', 'Sunset Jane', and 'Montezuma'.
Invasive species, such as cacti, can also have a detrimental impact on native biodiversity. While not a declared plant in South Australia, the spread of cacti is being monitored due to the ease with which it can establish new infestations. This highlights the importance of responsible gardening practices, such as harvesting fruit to prevent seeds from spreading, to protect Australia's unique environment.

States have quarantine restrictions for certain plants
Australia has a unique and diverse range of native flora, and the country takes biosecurity and plant health very seriously. To protect native species and essential food crops, there are strict regulations in place regarding the movement of plants across state borders. Each Australian state has its own quarantine restrictions on certain plants, and these regulations are regularly updated to reflect any changes in biosecurity.
For example, in South Australia, the state government has declared that Fountain Grass cannot be sold or traded. This is because the plant produces a large number of seeds that can easily spread, and it is an invasive species that can outcompete native species and reduce the nutritional value for wildlife. Similarly, Gazania, a colourful ground cover native to South Africa, is banned from sale in South Australia as it competes with native species and agricultural crops.
Some other plants that are restricted from being moved across state borders due to biosecurity concerns include Myrtaceae plants, which can carry the Myrtle Rust disease, and citrus plants in Queensland, which may carry Blueberry Rust. There are also additional high biosecurity restrictions in place for Tasmania and Western Australia, where certain plant families and materials, such as potting mixes and composts, cannot be sent.
It is important to note that these restrictions are in place to protect Australia's unique environment and agriculture industry. While some plants may be allowed in certain states, it is essential to check with local authorities before moving any plants across state borders to avoid the spread of invasive species and potential diseases.

Some plants are banned due to biosecurity concerns
Australia has a unique and diverse range of native plants, and the country takes great care to protect its natural environment and essential food crops. Some plants are banned due to biosecurity concerns, and these restrictions are regularly updated to reflect the current situation.
The movement of plants across state borders is restricted to protect food crops and maintain biosecurity and plant health. For example, due to the potential for the spread of Myrtle Rust, a plant disease, nurseries are restricted by law from moving certain plants across state lines. Similarly, Blueberry Rust has led to restrictions on the movement of citrus plants across borders.
Individual states have their own quarantine restrictions in place, and some plants are banned from sale within certain states. For instance, fountain grass is a declared plant in South Australia, meaning it cannot be sold or traded. This is because it produces a large number of seeds that spread easily, threatening the natural environment, and it also poses a risk to property in bushfires due to its high burning temperature. Gazania is another plant banned from sale in South Australia as it competes with native species and agricultural crops.
Invasive species are a particular concern, and while some invasive plants are banned, others are still available and can become a problem when they escape from gardens and establish in reserves. Some plants, like cactus, are not declared but are monitored due to the impact of their spread. Electric ants are another example of a non-native species that can cause issues, with restrictions in place to prevent their spread.
It is important for gardeners and nurseries to be aware of the regulations regarding prohibited plants, as these can vary between states and towns.

Some plants are illegal to move across state borders
Australia has strict biosecurity measures in place to protect its essential food crops and the health of its plant life. As a result, some plants are prohibited from being moved across state borders. These restrictions are in place to prevent the spread of diseases and pests, such as Myrtle Rust and Blueberry Rust, which can pose a significant threat to Australia's native flora.
Each state has its own quarantine restrictions for specific plants, and these regulations are regularly updated to reflect changes in biosecurity concerns. For example, citrus plants like lemons, limes, oranges, and kumquats are restricted from being transported across state borders in Queensland. Similarly, potting mixes and composts are prohibited from being sent to Western Australia due to biosecurity risks.
Some plants are banned from sale or trade altogether in certain states. For instance, Fountain Grass, a popular landscaping plant, is a declared plant in South Australia and is not allowed to be sold or traded. This is because it produces a large number of seeds that can easily spread, and it has low nutritional value for native wildlife. Another example is Gazania, a colourful ground cover native to South Africa, which is banned from sale in South Australia due to its invasive nature and competition with native species and agricultural crops.
It is important for individuals and nurseries to be aware of these restrictions and to check with local authorities before attempting to transport plants across state borders. Failure to comply with these regulations can have significant ecological and agricultural consequences.

Some plants are illegal to grow in gardens
In Australia, some plants are prohibited for food sale and cannot be imported, as outlined in the Australia New Zealand Food Standards Code. These prohibited plants include any part, derivative, or substance derived from the listed plants. For example, Cannabis sativa seeds are allowed, but only if they are low in THC.
Furthermore, certain plants are restricted from being moved across state borders to protect essential food crops and for biosecurity and plant health reasons. These restrictions vary by state and are implemented by state or federal governments. For instance, due to the potential disease threat of Myrtle Rust, nurseries are legally restricted from transporting Myrtaceae plants across state borders. Similarly, citrus plants are restricted from being moved out of Queensland.
In addition to these restrictions, some plants are advised against for gardening due to their invasive nature and potential environmental impact. For example, fountain grass, while popular for landscaping, can spread easily, reducing the nutritional value available for native wildlife and increasing the risk of damage in bushfires due to its high burning temperature. Gazania, a colourful ground cover native to South Africa, is also invasive in Australia, competing with native species and agricultural crops. It is banned from sale in South Australia, but some sterile cultivars are permitted.
Cactus plants are another example of a plant that can cause issues if allowed to spread. While not a declared plant, its impact is being monitored, especially in states with large-scale infestations. If left unmanaged, cactus pads can quickly grow into new plants, and dumped material can lead to new infestations. Therefore, it is recommended to harvest the fruit to prevent seeds from spreading into bushland by birds and other animals.
