A undeveloped stretch of hard sandstone slab with easy access.


A good cliff line broken into two, offering good height (~4m) slabs, on generally excellent rock with good landings. It's all around the V0-2 grade range with juggy top outs, so good for beginners. The first cliff (Left Nacelle) is slabby and more technical, while the second cliff (Right Nacelle) is easier. Choose your own sci-fi adventure! Easy landings and a short approach make this a good place for laps. You can do the whole crag in a long afternoon for endurance. Also 5mins walk from a beautiful swimming spot in the George's river.


  1. all new routes must have star trek related names (preferably TOS on right, TNG on left)

  2. kids can name any new climbs whatever they want

  3. try and use coloured chalk to minimise impact

  4. respond in the affirmative to all Duck quacks from nearby lagoon

Access issues inherited from Sutherland

For over 50 years climbers in the Sutherland Shire have enjoyed free access to many fantastic crags and caves. But as of 2014 there have been access problems emerging at several climbing and bouldering areas due to aboriginal art sites and shell middens in caves. Sutherland Shire Council and the Dept of Enviroment and Heritage have announced closures and sign-posted some of these aboriginal sites, with further closures and signs to be added during summer/autumn 2016/2017. Areas of particular problem are ground level overhangs with flat bases, the type of terrain popular at hard bouldering areas. Whilst the details are sorted out keep a low profile, clean up ALL rubbish (inc removing mattresses in bouldering caves) and avoid climbing at closed areas. In particular treat non-climbers you see at crags with the utmost respect as they could be rangers, archeologists, traditional owners or anyone else with a dim view of climbers and the ability to shut us out. Climbing in Royal National Park has been officially banned for many years - probably due mostly to the Wattamolla 'don't jump off rocks' cliff-diving-into-water ban. For more information about aboriginal sites and rockclimbing please read this link from Sutherland Council:


Park on the side of the road between the two bodies of water, just before the road heads back into bush towards picnic point: (Parking-33.978714, 151.002507). Cross the road to the Lagoon side, and walk west. You'll find a new little bridge. Across the bridge is the Yeramba Lagoon Walking track. Follow it for about 30 metres and the crag will be obvious on your left.


History timeline chart

Another one discovered in 2012, but undeveloped. Until.... Some bloke came along in the second 2021 lockdown and put up loads of climbs all with star trek names and renamed the whole thing. (Thanks for discovering this kind stranger, I hope you don't mind the name change)

Grade Route

Start in small finger slot on black streak and push up into edge facing down. Trend left and up.

FA: Tom Bes, 2021

Just to the right of black streak. Mini crimps and smear to gain whiteish ledge for foot on right. Up the slight outcrop to jugs of victory

FA: Tom Bes, 2021

Start with right hand on blocky sidepull and left hand low on whiteish ledge. Match foot up to ledge, pistol squat to glory.

FA: Tom Bes, 2021

Start with right hand in runnel and move into small 2 finger pocket. Smear feet and delicately move up to crimps and out

FA: Tom Bes, 2021

Start on the thin stuff 1 metre right from worf under the sidepull flake. Move into this sidepull, up on smeary feet and out to juggy top.

FA: Tom Bes, 2021

Start 2 metres left of wide crack. Up through slopey flake.

FA: Tom Bes, 2021

Warning Rock: High prominent thin flake is not too solid

Warning! Fragile flake! Up the right thin arete of the wide crack. I'm putting this route up here as it's the most obvious line but it's not safe to climb. I removed a loose block behind the thin high flake but the remaining thin flake isn't particularly solid. An easy climb but you might end up like season 2 Tasha Yar if you climb it.

Start with both hands on the runnel sidepull. Reach up to another sidepull. Then up and away

FA: Tom Bes, 2021

Burly. Sit start with hands left on low rail. Heave up using thin crimps. Top out rights for Wesley Crusher.

FA: Tom Bes, 2021

Sit start with hands on right side of low rail. Straight up then traverse right to top out as for Wesley Crusher.

FA: Tom Bes, 2021

Traverse from far right arete all across the big slab and top out via the top of the crack far left. Keep mid wall, beware thin flake high on right side of wide crack, have fun on the slab section.

FA: Tom Bes, 2021

The central station linking the two nacelles. A couple of ageing climbers and their kids took command for the crag's second tour of duty. While all attempts to stick to the Star Trek route-naming ethics were made, the young first ascentionists declared that: a) they didn't know what Star Trek was b) those names were too boring anyway. A vague space theme ensues.

Stand start directly below the tree. To climb, somehow squeeze between the branches and roots to top out amidst the mossiness left of the block. Pulling on the tree will see you sent to the brig. Unlikely to see many repeats by adults over 5ft.

FA: Marilla

Start below tree and traverse right to finish up Wombatonaut.

FA: Marilla

Follows the features just left of the arete. Top out via the sloping pinches and jugs on the block up top. Wombats are the first ascentionist's favourite animal.

FA: Marilla, Jul 2021

Head up just right of the arete to some sloping jugs on top. The discussion topic just before the FA was how astronauts went to the toilet.

FA: Leif.

Start from obvious, low sidepull where a chunk of rock was ripped off (ruining the onsight FA) and finish up Space nappies. Other hand holds out right if you need them, also created by tearing another chunk of rock off.

FA: James S

Right wall slightly further back. less slabby

Up the second runnel to the left of the big flake. (Not the mossy wet one)

FA: Tom Bes, 2021

Up main flake system in middle of wall

FA: Tom Beswetherick, 2021

Using the jutting foot under the first bulge, stay left of the arete and move through the bulges

FA: Tom Bes, 2021

Traverse from Uhura on right to far left. Stay low, nothing above the break. On right move up at first arete and out left onto small final slab. Topout here.

FA: Tom Bes, 2021

Up the fun jugs on the right of the arete. Also a useful downclimb

FA: Tom Bes, 2021
