Il-Bogan Lagoon from Thiedeke Road
Access verdict · tier 2 of 4 · confidence C (statutory inference, the weakest grade in the chain)
A lawful approach from Thiedeke Road, with caveats.
The chain below runs entirely across land the public has an established right to be on. It is a legal line, not a path: nothing here has been surveyed on the ground.
- 1 · Lawful, nothing to flag Every leg is ground the public may cross, and nothing about the chain needs a warning. Whether a built track runs along it is said separately.
- 2 · Lawful, with caveats A lawful chain with at least one thing about it that has to be said first. This page is here.
- 3 · Unconfirmed No lawful chain could be established from the public record. No route published.
- 4 · No lawful route Enclosed by land the public has no right to cross. No route published.

Getting to the start The trailhead coordinate, not the feature
The start is at -27.99700, 152.97122
That is Thiedeke Road, where the walk below begins — 1.3 km of it. Every link here goes to that coordinate and never to the feature itself, because a driving route to a waterfall is a driving route into the country above one.

-27.99700, 152.97122
The record does not say what reaches the start The roads layer leaves trafficability unstated on most of its rows, and it is unstated here. That is an absence of evidence, not an ordinary road: treat the last stretch as unresearched.
The coordinate is where the recorded way begins, read off the same layers as the walk. What the record says about a vehicle is above, and it describes this point rather than the drive to it. Whether the road is sealed, gated, or open today, and where a car may lawfully be left, are none of them things these records say — so treat the last few kilometres as unresearched, and the mapping service's route to them as its own work, not ours.

Every leg above is computed from cadastral geometry. Nobody has walked it, and no part of it is a path on the ground: it is the line along which the public record establishes a right to be. Where a leg names a way, that is what a managing authority has mapped down the same ground — it says nothing more about your right to be there, which the parcel already settled.
Caveats — what kept this off tier 1
- Corner-point junction. Two parcels in the chain meet at a single survey point. They are legally continuous public land, but the junction has no width on the ground.
- Watercourse crossing. The chain crosses a watercourse bed. The bed is State land by statutory inference, there is no structure, and the crossing is off in high flow.
- Measured crossing. The gap between the parcels either side of this crossing could not be measured from the geometry, which is a reason for more caution, not less.
Following it on the ground No published way to follow
at least half an hour out and back
at least a quarter of an hour there at least a quarter of an hour back
Walking only — nothing is counted for rest, water, photographs, navigation, or the state of the track. The climb on this route could not be measured, so the figure is flat-ground time and the real walk is longer.
No directions are published for this approach. The chain above is a statement about permission, not a path, and turning a run of parcels into "walk north-east for 380 m" would tell you where to walk on evidence nobody holds — including where a way is mapped along it, because what was measured is the chain and not the way. Steps appear here only for a route that follows a surveyed way end to end.
How much climbing No contour cover along this line
No profile is published for this route. The contour layer does not cross its line often enough to describe a climb, and a profile drawn from anything else would be a guess about the ground.

Map
Route map: 3 legs from Thiedeke Road, 1304.9 m in total.
What the colours mean
- Freehold or leasehold — no public access
- National park / protected estate — public land
- Road reserve
- Watercourse
- Track recorded by the managing authority
- Contour, every 10 m of height — nothing is implied about the ground between two of them
- Tenure unresolved — treated as no access
- Where your device says you are, shown only if you press the locate button — read as a rough fix, not a position, and never sent anywhere
- A place with a published approach — the pin is a link to it
- A place with none — every one is listed under the map with its tier in words
- The walk — the line the legs below describe, not a surveyed path
- The parcels it crosses — the evidence the walk is lawful
- Watercourse crossing — no structure, off in high flow
Names on the map come from the same official records as the rest of the page — road and track names from the cadastre and the access layer, watercourses and estates from their own layers. A feature the record does not name is left unlabelled rather than guessed at.
Sources, licences and dataset versions are listed in the footer of this page.
Every figure the map would draw — parcel references, distances, bearings and the crossing gap — is written out in full on this page, so nothing is only visible on the map. If the map does not load, nothing has been lost.
What this verdict rests on Grades compose to the weakest link
-
The destination sits on the parcel below B — provenance grade B: Official spatial record
Parcel 617620, recorded tenure "Watercourse". Being at the destination and reaching it are separate questions, and this page answers only the second.

-
Leg 1: 617430 carries a right of passage B — provenance grade B: Official spatial record
281.6 m at 96.2°. Read from the mapped parcel geometry in the official layer, with no inference beyond what the record states.
Leg reference 617430 Grade B
-
Leg 2: 617772 carries a right of passage B — provenance grade B: Official spatial record
609.2 m at 11.3°. Read from the mapped parcel geometry in the official layer, with no inference beyond what the record states.
Leg reference 617772 Grade B
-
Leg 3: 617620 carries a right of passage C — provenance grade C: Statutory inference
414.1 m at 247.3°. The bed is State land by statutory inference from the Water Act 2000 (Qld) s.21 — law applied to a mapped parcel, not a finding by any authority.
Leg reference 617620 Grade C
-
The chain is only as strong as its weakest link C — provenance grade C: Statutory inference
Confidence is not an average. It is the weakest grade in the chain above, which is why a single inferred leg holds the whole route at grade C.
Composition rule: weakest grade wins Applied at build time

What this page will never do
-
No user pins
Every fact here traces to a government layer or a statute and carries a grade, A to C. Community names are quarantined at grade D and labelled as such. Nothing on this page was dropped on a map by a stranger.
-
No invented lawfulness
Where tenure cannot be confirmed from the public record, the page says so instead of endorsing the route or quietly hiding it. Where no lawful corridor exists at all, none is published — the refusal is the answer.
-
No safety pretence
A tier is a tenure verdict, not a difficulty or safety rating. Unmanaged terrain, cliffs and flash flooding are not in the cadastre. The engine reads land records, not the weather.
