Lake Doonella from Blackbutt Court
Access verdict · Lawful, with caveats · weakest evidence in the chain: statutory inference
A lawful approach from Blackbutt Court, 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.
On-ground signage and temporary closures override this page. Always.
Getting to the start The trailhead coordinate, not the feature
The start is at -26.38647, 153.02254
That is Blackbutt Court, where the walk below begins — 5.4 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.
- Google Maps one link for a desktop browser, Android or iPhone
- Apple Maps the default on iPhone and Mac
- Your own map app hands the coordinate to an installed app, offline ones included
-26.38647, 153.02254
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 has to be said before walking this
- 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 narrowest gap between 9AP23771 and 1274953 is 69.18 m. There is no structure. Do not cross in high flow.
- Measured crossing. The narrowest gap between 1352891 and 1559953 is 1264.83 m. There is no structure. Do not cross in high flow.
- Measured crossing. The narrowest gap between 1274953 and 1570859 is 417.18 m. There is no structure. Do not cross in high flow.
- Measured crossing. The narrowest gap between 1559953 and 1528679 is 463.97 m. There is no structure. Do not cross 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 steps, but the record maps ground here
at least 2 hours out and back
at least 1 hour there at least 1 hour back
5 m up and 10 m down on the way out — so the return leg climbs 10 m.
Walking only — nothing is counted for rest, water, photographs, navigation, or the state of the track.
What is mapped along this chain
A managing authority has surveyed a way along 47 m of this 5377 m chain — about 1% of it. That is a statement about what is on the ground, not about your right to be there, which the parcels above already settled, and not a direction: no step below is measured along any of these ways.

Leg 6 McKinnon Drive Official spatial — evidence class
47 m along it · the managing authority publishes it as open to the public .
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.

The profile is the height the contour layer already records, read along the same line the legs above describe. It is not a survey of a path: nothing here says the ground between two contours is even, and a layer of 5.0 m contours cannot evidence a step smaller than the gap between them.

Map
Route map: 13 legs from Blackbutt Court, 5377.2 m in total.
What the colours mean
- Land — the council area the region is published under
- Water beyond the council boundary
- 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 verdict in words
- Where a published approach starts — each one has a page of its own below
- 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 for everything this map draws.
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.

The chain is only as strong as its weakest link Statutory inference — evidence class
Confidence is not an average. It is the weakest class in the chain above, which is why a single inferred leg holds the whole route at statutory inference.
