The cave faces north and is so large that it never actually gets the sun. However, it is notoriously "greasy" outside of winter so add a few grades. The cave is large enough to not get wet in the rain but it does seep occasionally. The rock is sandstone and very few (if any) holds are chipped.

Refer to map for 'Bomaderry Creek' Crags.Turn into Illaroo Rd off the Princes 'Highway' at North 'Nowra', just north of the Shoalhaven River. Take the 1st right which is Walsh Cres and follow it around until there is a bush reserve on your right. Park here and follow the track downhill for 30m. This is 'Mortein Wall', follow the track down past the cliff and turn right until you reach a huge cave with a big horizontal roof about 10m up. This is it. The bouldering gets harder the further left you go ...

Highball at far left end of Lot 33. Tops out to Lot 34. Stand start on 2 edges, move up into roof and committingly top out around the bulge.

FA: Paul Westwood, 2001

Far left bolted line on the face. Only been climbed on rope. Not yet highballed.

Set by Paul Westwood

FA: Chris Webb-Parsons

Sit start at the rail, big mantle up to the sloper. Then move up to finish with a big move to the hueco. The corner is often full of cobwebs but this is well worth quickly brushing them away.

FA: Jack Folkes, 23 Jul 2014

Crimpy stand start, up on crimps and sharp undercut to top at flake and dirty edge (no match).

FA: Jack Folkes, 3 Jun 2013

Stand start as for Corporate Takeover. Move up and right to top at decent edges.

FA: Jack Folkes, 5 Apr 2015

A big jump from a huge jug to another huge jug - the business is controlling the swing! The landing is a bit dodgy so pad it out and have a spotter.

FA: Joe Hodgson, 2000

Start under the roof with 2 undercuts (RH on pebble), move out to the lip and then traverse left and finish up "Joe, Joe Dynamo".

FA: Chris Webb-Parsons, 2006

Very crimpy, very hard looking project from the start of "Worm" straight up into the scoop. Old Paul Westwood project.

Start of "Worm" right into "Pissy Missy".

Start matched on a good hold, go RH to sidepull, some funky footwork and then LH up to jug in roof. Up to the pocket and same move again to finish.

FA: Paul Westwood, 2000

Link from the start of "56ft Back" and "Fed Ex" left along the low roof overlap and into "Pissy Missy". Looks in the range of V12-V13.

Low sit start at the back of the roof, big moves out following the break in the roof.

Links into 'Special Delivery'.

The lower link up into "Special Delivery". Worked for some time by CWP who thought it would be V14.

This problem goes out the steepest part of the roof. Start matched low on the horizontal rail then out to the LH gaston and then up to the RH 3 finger pocket. A big throw to the LH undercling pocket then up some good holds to a powerful finish at the big hueco.

Slot currently broken. Much much harder now.

FA: Paul Westwood, 2000

Sit start on the overhanging flake. Move up the good holds then out right to the hueco and finish with the big move. Ledge on the ground is NOT in!

Sit start on the flake. Move right via undercut to the big moves fridge hugging up to top. Ledge on the ground is NOT in!

Start at Sexy Rexy traverses right all the way to finish up Nappy Nuggets. Ledge on the ground is NOT in!

FA: Pete Tosen, 24 Aug 2010

Variant to Unknown. From the huecos, move RH to pocket and LH to good edge, nice move to jug and top.

Variation/link up. Start as for Unknown. From the huecos, move right through pockets to jug on The Crotty, then back up and left to jug and finish.

FA: Joe Hodgson, 2000

Starts right where the blue Lot 33 graffitti is. Awkward start to gain the sidepull/undercling with your RH. Then a long move LH to a shallow pinch, cross over with your RH to a pocket. Then up to the sharp LH crimp and a throw to the jug to finish. Ledge on the ground is NOT in!

FA: Paul Westwood, 2000
