Purling Brook from Mibum Lookout Track

entry is a track 20 m of climb chain confidence Statutory inference — evidence class purling-brook--from-mibum-lookout-track

Access verdict · Lawful, with caveats · weakest evidence in the chain: statutory inference

A lawful approach from Mibum Lookout Track, 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.

What this verdict means · what the evidence grades mean

On-ground signage and temporary closures override this page. Always.

Getting to the start The trailhead coordinate, not the feature

The start is at -28.19893, 153.25557

That is Mibum Lookout Track, where the walk below begins — 3.1 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.

-28.19893, 153.25557

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 5AP19371 and 5AP19371 is 0.00 m. There is no structure. Do not cross in high flow.

Following it on the ground No steps, but the record maps ground here

at least 1¾ hours out and back

at least three quarters of an hour there at least 1 hour back

20 m up and 160 m down on the way out — so the return leg climbs 160 m.

Walking only — nothing is counted for rest, water, photographs, navigation, or the state of the track.

Naismith's rule, and what it does not account for

What is mapped along this chain

A managing authority has surveyed a way along 533 m of this 3088 m chain — about 17% 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 3 Springbrook Road Official spatial — evidence class

    159 m along it · the managing authority publishes it as open to the public (Local Government Authority).

  • Leg 6 Mimosa Road Official spatial — evidence class

    329 m along it · the managing authority publishes it as open to the public (Local Government Authority).

  • Leg 9 Purling Brook Falls Circuit - Bitumen (Great Walk) Official spatial — evidence class

    44 m along it · the managing authority publishes it as open to the public (Queensland Parks and Wildlife Service).

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.

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.
