Plan (NAA150/1/525/20, I195) of Mount Coot-tha Naval Magazine and Mine Assembly Depot

Around Mount Coot-tha

Site ID	Description	Notes
1	Armco Magazine M1	Nothing clearly visible at site.
2	Armco Magazine M2	One edge of the concrete foundation was exposed to view in 2018
-	-	There is no Number 3 shown on the Plan. It may possibly relate to the "old non-magnetic hut" 20' x 30' that was originally located at the junction of Sir Samuel Griffith Drive and the Honeyeater Track/Reservoir Trail, located near No. 4 on the plan.
4	No name shown	This was situated beside the Reservoir Trail not far from the junction with the Chapel Hill Road Trail. All that remains of it in 2018 is a concrete slab covered in thick grass.
5	Armco Magazine A1
6	Armco Magazine M4
7	Armco Magazine A2
8	Armco Magazine A3	Exact location uncertain in 2018
9	Armco Magazine M6	Exact location uncertain in 2018
10	Armco Magazine M8	In 2018 the concrete foundation and some scrap metal remains were still visible alongside the Litchfield Trail
11	Armco Magazine MV	This should possibly have read as "M5". An easy walk from the Litchfield Trail.
12	Armco Magazine A4	In 2018 one concrete edge of the foundation was clearly exposed to view.
13	Armco Magazine A6	Overlooks the Litchfield Track near the Gold Mine Picnic area.
14	Armco Magazine A7	Overlooks the Litchfield Track.
15	Fibrolite Hut A5
16	Armco Magazine A7	That makes two A7s? Obviously an oversight. This site was still covered by a heavy layer of soil in 2018, with nothing directly visible.
17	Fibrolite Hut A8	Nothing clearly visible at site.
18	Fibrolite Hut A9	Nothing clearly visible at site.
19	Fibrolite Hut A10	Nothing clearly visible at site..

24	Quonset Hut A15	Nothing clearly visible at site.
25	Armco Magazine A18	Nothing clearly visible at site.
26	Quonset Hut A17	There are some depressions here and possible evidence of a turnaround for trucks, but there is nothing clearly visible at site of the Quonset Hut.
27	No name shown	Probably not built
28	Armco Magazine A19	Nothing clearly visible at site.
29	Armco Magazine M14	The concrete foundation is clearly visible off the northern side of the Powerful Owl Trail, but it is still easy to walk past this.
30	Armco Magazine M15	The exposed concrete edge of this can be clearly seen alongside northern side of the Powerful Owl Trail.
31	Armco Magazine M16	The concrete foundation is hidden off the southern side of the Powerful Owl Trail, but is still there.
32	Armco Magazine M17	This was at the end of the trail constructed by the Seabees. While not clearly visible, it is easy to envisage where this turnaround area was located.
33	Armco Magazine M18	This is on the site of the Channel 9 Television property, and as such this is a site that is not publicly accessible. Probably nothing to see there anyway. NOTE: There was also "Detonator Locker #1" located nearby, also on the Channel 9 site, which is shown on the map with no location number.
34	Fibrolite Hut A20
35	Armco Magazine A21	No physical evidence of this was seen in 2018.
36	Fibrolite Hut A22	This concrete foundation is located at a lonely bush spot some 100 metres from the road, in the bush. It is in very poor, exposed condition but in the right light makes for an impressive photo.
37	Fibrolite Hut A23
38	Armco Magazine M20	The remains of this Armco Magazine, if any are left, will be under grass within the property of the Channel 7 Television site. As such there is no public access.
39	Quonset Hut A24	This site is located across the road opposite Channel 7. There was nothing obviously visible to be seen here in 2018.
40	Fibrolite Hut A25	There was no physical sign of the foundation visible in 2018.
41	Armco Magazine M34
42	Fibrolite Hut A26	This magazine would have been situated at the current ABC TV site; it is not accessible to the public.
43	Fibrolite Hut A37	This magazine would have been situated at the current ABC TV site; it is not accessible to the public.
44	Armco Magazine M23	This magazine would have been situated at the current ABC TV site; it is not accessible to the public.
45	Armco Magazine M22	This would have been located beside the current Channel 10 TV Studio site. It is not accessible to the public.
46	Fibrolite Hut A28	This would have been located within the modern Channel 10 TV Studio site. It is not accessible to the public.
47	Armco Magazine A30	The exposed concrete edge is visible beside the bitumen road.
48	Fibrolite Hut A31
49	Armco Magazine M35
50	Not named	The lack of a name on the plan probably means that there was open storage of ammunition at this site with no building constructed.
51	Armco Magazine M25
52	Not named	The lack of a name on the plan probably means that there was open storage of ammunition at this site with no building constructed.
53	Armco Magazine M26
54	Not named	The lack of a name on the plan probably means that there was open storage of ammunition at this site with no building constructed. This location is now a car park at Simpsons Falls Picnic Area.
55	Armco Magazine M27
56	Not named	The lack of a name on the plan probably means that there was open storage of ammunition at this site with no building constructed. This location is now a car park at Simpsons Falls Picnic Area.
57	Armco Magazine M28	This location is now the last car park and turnaround area at the Simpsons Falls Picnic Area. A small section of the original concrete foundation of Armco M28 was visible through the bitumen cover in 2018.
58	Not named	The lack of a name on the plan probably means that there was open storage of ammunition at this site with no building constructed. This was located on what is now the Reservoir Trail.
	Not built Armco M24 (near 47)

	Detonator Locker No. 1	Located near 33.
	Detonator Locker No. 2	Detonator Locker No. 2 was just around the corner as you drive downhill from No. 47, in the clockwise direction. It has no location number on the map.
	Detonator Locker No. 3	Located near 49.
	Detonator Locker No. 4	Located near 49.
	Detonator Locker No. 5	Located on the left across the creek just past the Assembly Plant building. The remains of Detonator Locker No. 5 still exist. This was probably the smallest Detonator Locker at Mount Coot-tha.

	Water tanks	Located near No. 17.
	Old non magnetic hut	located near No. 5.
	Kiosk Hut
