            3.3 Topography
            The slope of land is a major determinant of fire behaviour. Fire burns faster as it travels upslope via
            preheating of unburnt fuels ahead of the fire front which increases the rate of spread and fireline
            intensity. Conversely, fires move more slowly as they travel downslope. Fireline intensity is a function
            of the rate of spread (QFES 2019).
            The site and surrounding landscape is positioned on near level to undulating coastal plain. The
            natural landform gradually inclines to the west away from the Lake Cooroibah foreshore. A small hill
            is present in the far east of the site where the existing dwelling is located and also to the north of the
            site.
            There are no major topographical landforms which shield the site from prevailing winds.
            Plate 5 depicts topography conditions within and adjacent to the site.
