Building a pergola is an exciting project that can enhance your outdoor space, providing shade, beauty, and a comfortable retreat. One of the most crucial decisions you'll make when constructing a pergola is choosing the right timber for the frame. The timber you select will determine the strength, durability, and overall aesthetic appeal of your pergola. In this comprehensive guide, we will explore the top timber options available in Australia, ensuring your pergola in Newcastle or Lake Macquarie is both strong and visually appealing.

  • Treated Pine:

Treated pine is a popular choice for pergola frames in Australia. It is a versatile and cost-effective timber option that has been chemically treated to resist decay, termites, and rot. Treated pine is readily available and easy to work with, making it a preferred choice for DIY enthusiasts. While treated pine may not have the same natural beauty as hardwoods, it can be stained or painted to achieve your desired finish. This timber option offers good durability and strength at an affordable price point.

  • Merbau:

Merbau, also known as Kwila, is a tropical hardwood that is native to Southeast Asia, including parts of Australia. It is highly regarded for its exceptional durability and strength, making it an excellent choice for pergola frames. Merbau timber is naturally resistant to decay, termites, and rot, making it well-suited for outdoor applications. Its rich reddish-brown color, attractive grain patterns, and natural oils contribute to its visual appeal. Merbau timber requires regular maintenance, such as staining or oiling, to preserve its natural beauty and protect it from weathering.

  • Spotted Gum:

Spotted gum is a versatile and durable Australian hardwood that is commonly used for outdoor structures, including pergola frames. It is known for its strength, natural beauty, and resistance to decay and termites. Spotted gum timber features a stunning mix of colours, including shades of grey, brown, and reddish-brown, which adds character and charm to any pergola design. Its high density and toughness make it well-suited to withstand Australia's harsh climate conditions. With proper maintenance, spotted gum can last for many years, providing a sturdy and visually appealing pergola frame.

  • Blackbutt:

Blackbutt is another popular Australian hardwood that is frequently used for building pergola frames. It is highly regarded for its durability, strength, and resistance to decay and termites. Blackbutt timber has a light golden color with a straight grain and uniform texture, providing a contemporary and elegant look to your outdoor space. It is a versatile timber that is easy to work with and can be stained or painted to achieve the desired finish. Blackbutt timber is well-suited to the varying weather conditions in Newcastle and Lake Macquarie, making it a reliable choice for pergola construction.

  • Ironbark:

Ironbark is a dense and durable Australian hardwood known for its exceptional strength and longevity. It is highly resistant to decay, termites, and fire, making it an ideal material for pergola frames, especially in areas prone to bushfires. Ironbark timber features a distinctive deep red to dark brown colour with subtle interlocking grain patterns, adding a touch of natural elegance to your outdoor space. While it may be more expensive than other timber options, its exceptional durability and resistance to weather conditions make it a worthwhile investment for a long-lasting pergola frame.

  • Jarrah:

Jarrah is a renowned Australian hardwood that offers exceptional durability and natural beauty. It is known for its rich, deep reddish-brown colour and unique grain patterns, which create a striking visual appeal. Jarrah timber is highly resistant to decay, termites, and rot, making it an excellent choice for pergola construction in Australia's challenging climate conditions. With its impressive strength and longevity, a pergola frame made from Jarrah will stand the test of time and provide a stunning addition to your outdoor space.

  • Cypress Pine:

Cypress pine is a softwood native to Australia and is widely used for pergola frames. It is naturally resistant to decay, termites, and rot, making it a suitable option for outdoor applications. Cypress pine timber has a pale yellow to light brown colour with a straight grain, offering a clean and classic look to your pergola. It is relatively lightweight and easy to work with, making it a popular choice for DIY projects. With proper care and maintenance, a cypress pine pergola frame can provide years of reliable service.


When selecting the right timber for your pergola frame, it's essential to consider factors such as durability, resistance to decay and termites, aesthetic appeal, and maintenance requirements. Each timber option has its unique characteristics, so it's crucial to align them with your specific needs and preferences.


Proper installation, regular maintenance, and sealing or staining the timber can significantly extend the lifespan of your pergola frame, regardless of the timber you choose. Additionally, consult local building codes and regulations to ensure compliance with any specific requirements.


Choosing the right timber for your pergola frame is vital to create a strong, durable, and visually appealing outdoor structure. Treated pine, merbau, spotted gum, blackbutt, ironbark, jarrah, and cypress pine are all excellent options to consider for your pergola construction in Australia. Each timber offers unique qualities in terms of strength, resistance to decay and termites, and aesthetic appeal.
