Fixed gear failures in Australian climbing

Previous title: "Bolt failures in Australian climbing"
Note: Post has been updated several times, last update 10/11/2021

Does anyone have a list of recent bolt failures - I'm trying to get a bit of a list going that can be used for educational purposes ?

Objective: Provide some sort of data to help out with the next:

-User guide to using bolts
-Bolting guide update
-Rebolters appreciation meeting/beer fund donations

I'll try to keep the scope to more modern fixed anchors (or those anchors which at first glance would appear to be modern anchors) eg. mild steel carrots would not be included (Typically pretty easy to spot), but stainless carrot bash ins would be (as they could be confused with glue in SS machine bolts), as would ring bolts placed with silicone only on the outside and no glue/grout.

Will plan to add other fixed gear notes as a separate list (eg. shifty lower offs, a few permadraw rope cuts etc.)

Obviously, all climbers are responsible for their own safety including their use of fixed gear.



Current list:

Inclusion: failure of bolt/hanger/bolt-glue interface/glue/glue-rock interface/rock blowout and failure of rock feature.

Including incident, near miss and incidental identification:


Loose rock:


QLD - Ninderry - Bolt in loose loose rock - 2020 (near miss)

ACT - Canberra Molonglo River - Sewer Wall - Sewer Wall - Expansion bolt in loose block - 2019 (near miss)

NSW - Rosa Gully -loose block with glue in in-situ found below Funky Moves - 2016

WA - Mountain Quarry - "Death Star" 2012 - Part of route fell off with bolt

NSW - Northern beaches - large block with 3*carrots now at base of climb ?date - Source: CW

TAS - Sisters Beach - smooth shafted glue in home made SS U bolts installed, Bolts reported to have fallen out under trivial loads (?near miss/rebolt) 2018






Glue failure:

QLD - Beerwah - Secret garden - reports of unset/soft glue - 2021 (?near miss)

WA- Kalbarri - absence of the bear - anchor bolt removed by hand. Glue in commercial P bolt, likely early glue failure ?cause 2021

NSW - Bluebell - GIMB/Hanger fell out - 2013 (near miss) - (thecrag note 2003 - "3rd bolt is mank and flex's")

NSW - Nowra - DZ - failure of 3rd bolt during cleaning - glue in ring - glue failed to set - 2007

NSW - Pierces pass - Randy rabbit - GIMB + chain - glue not set on 2 bolts Ramset101 cartridge glue - near miss (pulled when 2nd fell, likely catastrophic if leader had fallen) ?2013

QLD - Tibro - Ramset 101 - glue failure to adhere to rock ?cause 2000

Tas - Cataract Gorge - ?glue failure glue in U bolt - ?1990s





Expansion bolt unplanned disassembly:

QLD - Tibrogargan - Drop in anchor (?brand) - screw+hanger dropped out during lower - 2020 (near miss)

VIC - Ravine crag - Lead fall on 5th bolt, ?hang and nut (expansion bolt) popped off 4th bolt (near miss) - 2013

VIC - Ravine - expansion bolt nut unscrewed in lead fall - no injury - 2013






Expansion bolt mis-installation:
ACT - Orroral ridge - Penny - loose dynabolt (?bolt vs hole issue) 2021

NSW - Pierces pass - 8mm partially installed expansion bolts used on route - contributing factor in death 2009

There's that hilarious giant block sitting down on the rock platform at Freycinet with two bolts in it. Used to be the top 5m of a route.

I'm not really sure that blocks falling out with bolts in them count as bolt failure though.
