Mount Mumdjin from minimally formed natural track off Springbrook Road

entry is a track 247 m of climb chain confidence B — provenance grade B: Official spatial record mount-mumdjin--from-minimally-formed-natural-track-off-springbrook-road-3
  • A Gazetted / register — The fact is itself a statutory record.
  • B Official spatial record — Read from a maintained government layer.
  • C Statutory inference — Law applied to B-grade records; not ground-truthed.
  • D Community record — Community sources; labelled, never blended into A–C.

Access verdict · tier 2 of 4 · confidence B (official spatial record, the weakest grade in the chain)

A lawful approach from minimally formed natural track off Springbrook 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. 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. 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. 3 · Unconfirmed No lawful chain could be established from the public record. No route published.
  4. 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 -28.22833, 153.27335

That is minimally formed natural track off Springbrook Road, where the walk below begins — 1.9 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.

-28.22833, 153.27335

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.

Total 81.9 m mapped 1864.3 m Chain confidence B — provenance grade B: Official spatial record

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.

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

at least 1¼ hours out and back

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

247 m up and 15 m down on the way out — so the return leg climbs 15 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 82 m of this 1864 m chain — about 4% 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 1 Springbrook Road B — provenance grade B: Official spatial record

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

  • Leg 4 Repeater Station Road B — provenance grade B: Official spatial record

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

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 1.0 m contours cannot evidence a step smaller than the gap between them.

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.

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