The site gently slopes in a northerly direction from the southern boundary at approximately
RL 5 AHD down to the northern boundary at approximately RL 3 AHD.

3. Regional Geology and Acid Sulfate Soil Conditions

3.1    Regional Geology

Reference to the Geological Survey of Queensland’s detailed surface geology mapping indicates
that the site is underlain by Late Triassic to Early Jurassic aged Myrtle Creek Sandstone described
as typically comprising “Deeply weathered quartzose sandstone, siltstone, shale conglomerate,
coal” boarding close with nearby Quaternary aged swamp and heath deposits in coastal areas to
the north.

The natural subsurface conditions encountered during the field work typically comprised
localised sandy silt, and silty, sandy clays inferred to be possibly residual, which is considered
consistent with the deeply weathered profile described above.
