The slope of a property can affect the behaviour and speed of a bushfire, with fire traveling faster and with greater intensity when on an uphill slope.

If your property has a slope on either the Northwestern or Eastern zone you will need to measure the degree of the slope.

The easiest methods for measuring the degree of a slope is to either use a clinometer (also known as a tilt meter), or to use the "walking method", which can easily be done without having to purchase any equipment.

The Walking Method

• If the slope is easy to walk up, but would be difficult to cycle up, you could use a slope between 5 and 10 degrees
• If the slope is difficult to walk up, or you wouldn't consider driving a 2WD car up, use between 15 and 20 degrees
• If the hill is a struggle to get up at all, use 20 degrees or greater.

Here is an example:
