Australia's natural landscape is dominated by evergreen eucalypts, which do not lose their leaves in autumn. However, due to the legacy of European settlement, many gardens and streets in Australia are lined with deciduous trees native to the northern hemisphere. These trees lose their leaves in autumn, and their colourful displays attract thousands of tourists each year. The best places to see autumn leaves in Australia include the Adelaide Hills in South Australia, Macedon Ranges, Dandenong Ranges, and the High Country in Victoria.

Why leaves change colour
Australia's natural landscape is dominated by evergreen trees, such as eucalypts, which have tough waxy leaves that can withstand the harsh conditions of winter. However, in the southern and cool mountain regions, the leaves do change colour in autumn, and tourists flock to these areas to see the display of fall colours. The leaves on deciduous trees turn forests, parks and gardens a rainbow of yellows, oranges, reds and browns.
Deciduous trees lose their leaves to conserve energy during the winter months. The shorter days mean there's less sunlight for trees to drive photosynthesis, which the trees rely on for energy. As the tree breaks down chlorophyll from green leaves, they lose their green colour. Chlorophyll turns sunlight into tree food through a process called photosynthesis. In summer, when it is very sunny and warm, plants photosynthesise a lot. When autumn comes, with its shorter, cooler days, deciduous trees know it's time to prepare for winter.
The red and purple colours are produced by a chemical called anthocyanin. This chemical can also help protect leaves from becoming sunburnt or being eaten by insects. Some trees have anthocyanin in their leaves throughout the year, but many only produce this chemical in the autumn. It reacts with glucose (sugar) held within the leaves to produce the red and purple pigments. Maple leaves are particularly renowned for their beautiful autumn colours because their leaves contain a lot of glucose, which increases the production of anthocyanin. The yellows and oranges are caused by varying amounts of a chemical called carotenoids (also responsible for making carrots orange!). Browns are generally caused by tannins.

Why leaves fall
In Australia, the natural landscape is dominated by evergreen eucalypts. However, in urban environments, streets and gardens are lined with deciduous trees native to the northern hemisphere. These deciduous trees lose their leaves to conserve energy during the winter months.
Deciduous trees lose their green colour as they extract and break down chlorophyll from their leaves. Chlorophyll is a natural chemical that captures sunlight and turns it into food for the tree through photosynthesis. In the summer, when it is sunny and warm, plants photosynthesise a lot. However, in the autumn, with shorter and cooler days, deciduous trees prepare for winter by breaking down the chlorophyll in their leaves and sending the nutrients to the roots to be stored underground.
As the chlorophyll breaks down, the leaves start making anthocyanins, the same group of pigments that turn apples and strawberries red. The red and purple colours are produced by a chemical called anthocyanin, which can also help protect leaves from becoming sunburnt or being eaten by insects. Some trees have anthocyanin in their leaves all year, but many only produce this chemical in the autumn. It reacts with the glucose (sugar) in the leaves to produce red and purple pigments. Maple leaves are particularly known for their autumn colours because their leaves contain a lot of glucose, increasing anthocyanin production.
The yellows and oranges are caused by varying amounts of carotenoids, the chemical that also makes carrots orange. The brown colour is generally caused by tannins.

Where to see autumn leaves in Australia
While Australia's natural landscape is dominated by evergreen eucalypts, the legacy of European settlement has introduced deciduous trees to the country's gardens and streets. As a result, there are several places in Australia where you can see autumn leaves.
Canberra
The country's capital city is renowned for its lush autumn street scenes. Grant Crescent, an avenue of towering American elm trees, is a popular spot for social media snaps.
Mount Macedon
This tiny hamlet, less than an hour north of Melbourne, is awash with stunning autumn colours and open gardens. Honour Avenue is a must-visit, as are the open gardens at Tieve Tara and Forest Glade, where maples, birches and beeches abound. The nearby towns of Woodend and Kyneton also have beautiful leaves on display.
Dandenong Ranges
The Dandenong Ranges, east of Melbourne, offer the perfect day trip to view the changing fall colours. While there, you can visit galleries, cosy tea rooms, and boutique shops or ride the classic steam train, Puffing Billy.
NSW Southern Highlands
The picturesque towns of Bowral and Mittagong are an easy day trip from Sydney and are ablaze with autumn colours.
Tasmania
Tasmania is ruggedly beautiful at any time of the year, but in autumn, it truly comes alive, with a spectacular display of red, orange and golden hues. An autumn road trip through the region is the perfect way to see the changing colours. One of the most unique experiences is the 'turning of the Fagus', where the Tasmanian Deciduous Beech tree transforms from green to vibrant reds, oranges and golds.
Daylesford
Daylesford, in Victoria's north-west, puts on a spectacular display of autumn glory in the fall months.
Toowoomba
The regional city of Toowoomba, two hours inland from Brisbane, has a cooler climate and is known as the Garden City. It puts on a vivid show in autumn and even boasts its own autumn leaf trail.

Why leaves fall before winter
In Australia, the natural landscape is dominated by evergreen eucalypts. However, the legacy of European settlement has introduced many deciduous trees, which lose their leaves before winter. Deciduous trees shed their leaves to conserve energy during the harsh winter months. With shorter days and less sunlight, there is less energy available for trees through photosynthesis.
Evergreen trees have tough waxy leaves that can withstand the cold, but for broadleaf trees, it is harder to keep their leaves healthy. As the tree breaks down chlorophyll from green leaves, they lose their green colour, revealing reds, oranges, yellows, and browns. The red and purple colours are produced by a chemical called anthocyanin, which also helps protect leaves from becoming sunburnt or being eaten by insects.
As leaves fall, the plant enters a state of dormancy, saving its energy for the spring. The process of leaves falling is called abscission, which is caused by a hormone called auxin. Auxin helps plants grow and turn towards the sun to absorb more light. When temperatures drop, auxin production slows, causing the abscission layer to break and leaves to detach.
Additionally, winter months tend to be windier, and the weight of snow on broad leaves could cause breakage. By shedding their leaves, trees can retain water and require less energy to survive the winter. The fallen leaves also add nutrients to the soil, providing a fresh start for the plant in spring.

Why leaves change colour in autumn
In Australia, the natural landscape is dominated by evergreen eucalypts. However, in urban environments, streets and gardens are lined with deciduous trees native to the northern hemisphere. In autumn, these trees change colour and lose their leaves.
Deciduous trees lose their leaves to conserve energy during the winter months. As the days get shorter, there is less sunlight for trees to drive photosynthesis, which they rely on for energy. The trees extract as many nutrients as possible from their leaves, storing them in the woody parts of the tree. The leaves change colour and eventually turn brown and dry, then fall to the ground.
The colour change occurs when the tree breaks down chlorophyll in the leaves, which causes them to lose their green colour. The leaves start making anthocyanins, which produce red and purple colours. Some trees have anthocyanin in their leaves all year round, but many only produce this chemical in the autumn. The yellows and oranges are caused by carotenoids, and browns are generally caused by tannins.
In Australia, the leaves in the southern and cool mountain regions, as well as in parts of Tasmania, start to change colour in autumn, attracting tourists to view the fall foliage. Popular destinations include Mount Macedon, the Dandenong Ranges, and the High Country in Victoria, the Southern Highlands in New South Wales, and Mount Tamborine in Queensland.

Frequently asked questions
Yes, in the southern and cool mountain regions of Australia, the leaves change colour in autumn, displaying hues of red, orange, yellow and brown.
Leaves change colour due to a reduction in chlorophyll, which gives them their green pigment. This reduction signals to the tree that it's time to prepare for winter. The leaves then produce anthocyanin, a chemical that protects them from sunburn and insects, resulting in red and purple colours.
Deciduous trees lose their leaves to conserve energy during winter. They extract nutrients like phosphorus and nitrogen from the leaves and store them in the woody parts of the tree.
There are several places in Australia known for their autumn colours. These include the Dandenong Ranges, Macedon Ranges, Adelaide Hills, Tasmania, and the NSW Southern Highlands.
