Ive been looking into this for a while now and always try and find more info on it whenever I can.
This topic was first brought to my attention close to 4 or 5 years ago while listening to John Faine's morning radio show on 774ABC melbourne.
He had a guest who was doing an investigation into the rumour of vast military complex underneath melbourne. His got stuck on to the story when he
bumped into someone who's father confessed to the secret on his deathbed that he was involved in constructing these complexes many decades earlier
and that they had all been sworn to secrecy of their involvement. This investigator was hoping his mentioning of this on radio might trigger a memory
in someone listening to out what information they had.
Funnily enough the bloke was cut off after the next add and they didnt even mention him anymore or take any calls from listeners.
anyway, in my time looking into this, I have found (thou i dont have any documention, thou it may be worth looking into), that these complexes were
begun straight after world war one....supposedly the world powers knew that there would be a second world war soon and were feverously constructing
and preparing for "the great War".
The government constucted these bases from townsvillle to melbourne with the military plan of "giving" away Northern part of australia in an
imaginary line across the continent through Brisbane, in the event of an invasion from the north. They thought this is how far they (the invaders)
could get before they suffer supply route issues and allies come to Australias defence.
In the event this wasn't succesful they were to cut back to a line through Sydney (were some of the tunnels and comlexes were found whilst
constucting the underground railway), and in tern, a worst case scenario was to be a last stand at Melbourne.
The Melbourne complex is supposedly extremely large, part of it includes a smaller(thou still pretty large bunker underneath the spencer street
staion, and one other elswhere).
This major bunker supposedly housed a massive amount of ammunition, weapons, ordinance, tanks, trucks, uniforms, all sort of supplies.
It had about 5 tunnels running away from it upto 15km into the bushland (of which is now suburbia) and after the war, they sealed all the entrances to
the tunnels with concrete 7 metres into the tunnels to stop anybody ever snooping or getting into them.
One I remember being mentioned was near Koroit Creek in Sunshine or Ardeer or thereabouts, which I beleive someone once found thou it is very
overgrown. and one in the northern suburbs somewhere.
Another major reason for this investigator finding this bunker complex was for safety reasons......the explosives must be past their use by date and
he mentioned someone inside the government had mentioned this to him to try and find it so that government officials can get this stuff out before
suburbs start blowing up underneath and the federal government will be in all sorts of # after that.
One other rumour was a bunker underneath Avalon airfield and a tunnel connecting this airfield with the one in Melbourne.
There is also a private organisation that I had been in contact with that was exploring these old bunker complexes in consultation with government
officials, but whether they found any of the big ones of mentioned them on their website is anybody's guess.
Heres a bunker entrance at Northcote in Northern Melbourne-
A team in Melbourne led by Mark Rawson is excavating a tunnel at Northcote in Merri Creek which was used by the military during WW2. The tunnel was
sealed and filled in after the war with dirt and rock. During WW2 a sentry was posted on the Merri Creek entrance to the tunnel.
It has been reported that there was apparently a boat moored near Swanston Street on the Yarra River during WW2, and in the event of an air raid, the
occupants of the War Room at Victoria Barracks would be whisked away up the Yarra to a large bunker at Dights Falls at Abbotsford. This is not far
from the Merri Creek tunnel. Could there be some connection between the two locations?
By late November the team were 165 feet in from the entrance of the tunnel. So far all they have found is lots and lots of dirt and rocks! The project
team have installed extensive timber-shoring inside the tunnel. By early December 2002 they believed that they were close, only a matter of 6 to 12
feet from finding something interesting. They believe they have also now found the entrance to the right hand tunnel. It is also packed with rock.
There was some suggestion of the main tunnel doors being in nearby Short Street.
There are reports that there used to be a large underground "bunker" near Dights Falls at Abbotsford, in Melbourne, Victoria. It is believed that
this large underground "bunker" was an old WW2 air raid shelter. It is estimated that it could hold a few thousand people.
It is reported that there was apparently a boat moored near Swanston Street on the Yarra River during WW2, and in the event of an air raid, the
occupants of the War Room at Victoria Barracks would be whisked away up the Yarra to this "bunker".
It is reported to be similar to the underground "bunker" under Spencer Street Railway Station in the Melbourne CBD.
If I find anything more I'll post it up here as this interests me and I would love to be involved in an exploration team to find these entrances,
particular the Koroit Creek one as its near my home.
I hoped this has helped you out abit, I understand abit of it is 'heresay' but with these sort of things and because of the long timelines involved
thats the best we can do with at times and it may be worth chasing up some rumours.
Have a happy new year ATS'ers
