We want our clients to have all of the info they need to make smart, educated, and sound decisions about their preferred fuel! Firewood is an incredibly sustainable way to heat a home, so let’s lay the facts on the table!

Shipping fees are calculated based on the proximity to our yard. When you place your order, entering your address will enable us to calculate shipping costs automatically.

Sustainability is fundamental to us at Sydney Firewood. That’s why we’re proud to be part of the Firewood Association Of Australia. This membership ensures that every piece of firework you order is ethically and sustainably sourced.

We sell firewood by tonnage. We sell sizes of 1,2 and 3 tonnes. If you’re looking for bulk orders larger than those, contact us for more details!

Water is present in all living trees as sap. Depending on the species, there can be more water in wood by weight than wood fibre. Moisture content in wood is expressed as the percentage of water by weight compared to oven-dried wood.

If the water weight in a piece of wood is the same as the wood’s oven-dried weight, then the moisture content is 100%. For wood to burn well, it needs to be less than 25%, preferably between 12% and 20%. Except in arid climates, 12% is as low as wood moisture content will get.

The best way to tell if the wood is dry enough to burn is to test it with an electrical resistance moisture meter. FAA members will have one of these. Otherwise, you can usually pick dry wood from green by its weight; it will feel comparatively heavy. Or you can split a piece in half and see if the middle is a lot darker than the outside.

The surface of freshly split wood will also feel cool to the touch if it is green due to the water evaporating. As a rough rule of thumb, it will take about 6-12 months for green wood to get below 25% if it has been cross-cut into 300 mm rounds (this depends on the diameter of the log and the initial moisture content).

That’s a difficult question to answer, as everyone uses firewood in different ways and at different rates. To conserve firewood, only burn as much as is necessary at a given time. If you’re using firewood in a wood furnace, they tend to be pretty efficient, even in colder weather. If you have a roaring campfire every night, your wood reserves will dwindle much faster. For more information, please contact us!

The answer depends to a large extent on what wood is available. For example, in Western Australia, Jarrah and Wandoo are considered the best. In Tasmania, Brown Peppermint is considered best. In South Australia, Victoria and southern NSW, it is generally River Red Gum. In Queensland, Ironbark and Box are preferred.

It also depends on what you are using the wood for. Red Gum is excellent in a slow combustion heater but does not burn with many flames, so other species are usually preferred for open fires. Some species are known not to burn well, Turpentine and White Stringybark being two of these.

Each species has its characteristics of burning rate, flame, coal and ash generation, which mainly relate to wood density and the chemical composition of tannins etc.

Perhaps the best thing to do is try a range of the available species and pick the most suitable, which may be a mix of quicker and slower burning species.

Firewood Facts


Trees store solar energy. It may sound strange, but allow us to break it down for you. Trees capture the sun’s energy via a process called photosynthesis. This process enables the trees to grow and become stronger, therefore INCREASING their ability to capture more and more solar energy.

Throughout human history, we’ve used that stored solar energy utilising fire. We use it for heat, cooking, light, and power.


Some of you may be thinking, “Well, that’s impossible! Firewood can’t possibly be green energy, can it?”. Green energy has a few definitions. Still, one that is commonly referred to is that green energy must be from a renewable source. Although one has to burn firewood to gain energy from it, it is renewable. Part of what companies like Sydney Firewood and associations like the FIREWOOD ASSOCIATION OF AUSTRALIA do is ensure that only sustainable farming and logging practices are used to collect and distribute the firewood.

By definition, trees are a renewable resource—and as long as we take care, plan properly, and distribute only firewood that is ethically harvested—we’ll have beautiful, renewable firewood as an energy source until the end of time.


Here are a few mind-blowing facts:

  1. Firewood releases less co2, methane, and carbon monoxide than all other sources of heat energy.
  2. As trees grow, they absorb the co2 that other trees have emitted while burning.
  3. Burning a tree to heat your home creates no more greenhouse gases than a tree left to rot and decompose in the forest.
  4. The only increase to the earth’s carbon dioxide brought about by the firewood life-cycle happens during transportation by vehicles that use fossil fuels.


Once solar panels are installed on your home, they no longer emit any greenhouse gases, and they no longer contribute to deforestation and climate change. However, we need to look at the processes involved in the creation of so-called green energy systems.

Solar panels are created using rare earth minerals. These minerals, for the most part, must be pit-mined. These pit mines are dug where there is forest and other vegetation and animal life. The result of pit-mining is a complete and utter obliteration of the area’s natural ecosystem, which will likely never fully recover.

Batteries have the same issues. An electric vehicle uses a rechargeable battery to get your family from point A to point B. However, that battery has to be produced somehow—typically via unsustainable mining practices.

Wind farms are equally reliant on unsustainable practices. Massive amounts of fossil fuels are burned to build, ship, and install wind farms. When the electricity is finally collected, it is stored in batteries which, as we know—are relatively inefficient.
