Rankins Falls from Powerline Walk Link 4
Access verdict · Lawful, nothing to flag · weakest evidence in the chain: official spatial record
A lawful approach from Powerline Walk Link 4.
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 -28.17273, 153.26039
That is Powerline Walk Link 4, where the walk below begins — 5.3 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.

Four-wheel-drive only The roads layer marks the road reaching this point as four-wheel-drive. A vehicle that gets most of the way along a road like this can still be stopped by the last of it.
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.
Following it on the ground Every step ends at something you can check
at least 3½ hours out and back
at least 1¾ hours there at least 1¾ hours back
400 m up and 370 m down on the way out — so the return leg climbs 370 m.
Walking only — nothing is counted for rest, water, photographs, navigation, or the state of the track.
The way reaches this place Official spatial — evidence class
Powerline Break (Great Walk) passes 3 m from the recorded point. The gap crosses no contour, which is as level as this layer can evidence — not a survey saying the ground is flat.
Both gaps are small enough that the way is a way to this place, not merely one near it.

5330 m in total, along the way the managing authority publishes. Every step above ends at something the records let you check on the ground. Bearings are true, not magnetic: they match a phone compass with no conversion. In this part of Queensland a magnetic bezel reads about 11° east of them, so an analogue compass needs that taken off before you set it.
What each step ends at, and why Official spatial — evidence class
- contour
- A mapped height. Checkable on a phone, and nothing else on the ground marks it.
- estate
- The boundary of a named protected estate — usually signed, but not always.
- watercourse
- A named watercourse crossing, from the official watercourse layer.
- junction
- A junction with another published way. Unmissable on the ground, and the place a wrong turn happens.
- destination
- The place itself, which is always where the last step ends.
A cadastral parcel boundary is never one of them. It is invisible on the ground, so a step that ended at one could never be checked — however convenient it looks in the data.

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 line on the ground
Map — covers Gold Coast
Route map: 13 legs from Powerline Walk Link 4, 5321.7 m in total.
Panning stops just outside Gold Coast, because the map archive is published one council area at a time. Every other council area Public Trails covers has a map of its own.
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.
