1. Introduction
This report documents selected physical findings recorded over a three-year period during field investigations conducted in southeast Queensland and northern New South Wales.
The material presented here is not claimed as definitive proof of an undiscovered primate species. Rather, it represents documented observations for which conventional explanations have been examined and, where possible, excluded based on terrain, environmental conditions, and species distribution.
All photographic material included in this summary has undergone internal review prior to publication. Known alternative explanations — including human activity and recognized Australian fauna such as feral pigs, dogs, horses and macropods — have been considered in each instance.
This report represents a sample of collected material and is not exhaustive of the full body of field documentation.
2. Footprint Findings
Multiple large bipedal impressions have been recorded during field operations between 2012 and 2013.
Measurements are taken at maximum length.
2.1 June 2012
-
Length: 46 cm
-
Location: Withheld (research area)
-
Terrain: Remote bushland
-
Notes: Single large impression; no associated vehicle or human traffic in immediate vicinity.
2.2 January 2013
-
Length: 26 cm
-
Location: Withheld
-
Notes: Smaller impression located within broader activity zone. Potential juvenile size range.
2.3 April 2012
-
Length: 36 cm
-
Location: Withheld
-
Terrain: Forested corridor
-
Notes: Isolated impression; substrate stable at time of recording.
2.4 June 2013
-
Length: 39 cm
-
Location: Withheld -Notes: Found in semi-remote area with limited public access.
(NB - Images used are from various locations)
Observational Commentary
Australia does not have native bear species, removing a common source of misidentification seen in North American footprint cases.
In each instance, known animal tracks were considered and excluded based on shape, stride context (where applicable), and absence of associated quadrupedal impressions.
Human origin cannot be excluded without forensic testing; however, the size and isolation of certain impressions reduce the likelihood of casual human presence.
3. Ground Nest Structures
Several large ground-based nest structures have been documented within research zones. Measurements were recorded at time of discovery.
3.1 Sunshine Coast – August 2012
-
Diameter: 2 meters
-
Terrain: Elevated bushland
-
Notes: Compressed vegetation forming circular depression.
3.2 Sunshine Coast – April 2011
-
Diameter: 2.7 meters
-
Notes: Similar spiral patterning observed. Comparable in scale and form to the previous structure.
3.3 Tree-Base Nest Structure
-
Location: Withheld
-
Notes: Located at the base of a tree where separate arboreal observations were recorded (refer Tree Baby Report).
-
Behavioral comparison: In known great ape species, adults may construct ground nests near arboreal nesting sites, particularly dominant males.
4. Biological Exclusion Assessment
Terrain conditions and structure size reduce the likelihood of construction by known Australian fauna.
Consultation with biologist Gary Opit indicated that no recognized Australian species constructs ground nests of this size and configuration within the documented environments.
Natural causes such as windfall, storm damage or random vegetation collapse were considered; however, spiral compression patterns and repeated structural consistency warrant documentation.
5. Conclusion
The material presented in this report does not constitute definitive biological proof of an undiscovered primate species in Australia.
However, the size, repetition and structural similarities observed across multiple locations justify continued documentation and investigation.
Further work should include:
-
Controlled measurement protocols
-
Soil and substrate analysis
-
Comparative primate nest modelling
-
Broader ecological baseline studies
The findings remain unresolved.
Documentation continues.
