The presence of Estuarine Crocodiles (Crocodylus porosus) in Trinity Inlet is well known, and they are likely to utilise the waters of Sunny Bay during feeding and migration. Beaches off Cairns are regularly closed in response to crocodile sightings.
There are recent anecdotal reports of crocodiles seen off Second Beach, just 2.5 km south west of False Cape.
The deadly Box Jellyfish, Chironex fleckeri inhabits north Queensland waters. This large, almost transparent invertebrate is common in coastal waters during the warmer wet season months, when it actively hunts fish. Its venom is amongst the most virulent known, and it can kill fit, healthy people in a few minutes .
Beach closures due to Box Jellyfish are an accepted fact of life in tropical northern Australia. Although some beaches are protected with nets, there are none in the East Trinity area, therefore swimming is generally out of the question during the hot summer months. Even wading can be deadly.
The heavy wet season rains provide ideal breeding condisions for insects. Both mosquitoes and march flies (biting, blood-eating flies of the family Tabanidae) are common in the hillside forests of the False Cape area.
Tiny, blood-feeding sandflies are also common in coastal areas.
The area of the development is heavily infested with termites. Pole homes, as enforced by the terrain, will require saturation chemical treatment to the poles before delivery to the site, and will require maintenance of ongoing heavy chemical treatment. Termites have not been considered in the Public Environment Report (HLA-Envirosciences 2004) and buildings located so close to the waters edge could create extensive problems with pollution from chemicals used to treat termites.
Cyclones are an irregular and destructive force of the Tropical North. They bring with them storm surges, torrential rains and destructive winds.
Rainfalls of > 300 mm associated with cyclones are not unusual, and the torrential downpours often causes erosion and landslides in steeper areas. Flooding, treefalls and rock slides associated with cyclones can block low-lying roads for hours, event days.
The destructive winds associated with cyclones also cause considerable damage, blowing over trees, damaging infrastructure and destroying overhead powerlines, leading to power interruptions that can last for days.
