Public Trails Computed from official land records

Seventeen Mile Creek from Avondale Road

entry is a road 10 m of climb chain confidence Statutory inference — evidence class seventeen-mile-creek--from-avondale-road

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

A lawful approach from Avondale 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.

Getting to the start The trailhead coordinate, not the feature

The start is at -27.54027, 152.94631

That is Avondale Road, where the walk below begins — 3.2 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.

-27.54027, 152.94631

An ordinary car reaches the start The roads layer marks the road reaching this point as trafficable by an ordinary vehicle.

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 2763931 and 337144 is 471.85 m. There is no structure. Do not cross in high flow.
  • Measured crossing. The narrowest gap between 337144 and 2268112 is 404.79 m. There is no structure. Do not cross in high flow.
  • Measured crossing. The narrowest gap between 334180 and 2268188 is 14.09 m. There is no structure. Do not cross in high flow.
  • Measured crossing. The narrowest gap between 2268112 and 2267694 is 81.82 m. There is no structure. Do not cross in high flow.
  • Measured crossing. The narrowest gap between 2268188 and 337714 is 275.73 m. There is no structure. Do not cross in high flow.
  • Measured crossing. The narrowest gap between 2267694 and 336840 is 269.74 m. There is no structure. Do not cross in high flow.
  • Measured crossing. The narrowest gap between 336840 and 2790227 is 1091.25 m. There is no structure. Do not cross in high flow.
  • Measured crossing. The narrowest gap between 2778067 and 2791595 is 0.00 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 published way to follow

at least 1½ hours out and back

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

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

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.

  • 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.
