The Australian flag which graced the sky of the nation's capital on Sorry Day in 2008 is being stored under strict conditions until it is assessed to determine its national heritage significance.
The flag, which billowed in the wind over Parliament House on May 26, 2008, weighs 20 kilograms and has dimensions larger than a double decker bus.
It has not been flown since that day six years ago in order to keep its physical form intact.
A Department of Parliamentary Services spokeswoman said a previous secretary requested the flag be kept but it has not been formally assessed for its heritage significance.
"The department has adopted a procedure to identify and assess items that may have heritage significance based on the guidelines and criteria published by the Collections Council of Australia," she said.
Even though each individual flag is numbered and can be traced back to any nationally significant day it was flying, the Sorry Day flag from 2008 was decommissioned to protect it from further wear and tear.
It is currently the only flag being stored for possible future assessment.
For 10 years, Jason Carew has been one of the "caretakers of the flag", known as a mechanical services maintenance officer.
"It's 101 metres in total … we have been asked for other people to go up the flag pole for the view, or to look or just to say they've done it, but it's a high risk job and it's our worksite," he said.
"We go up there to do it and come straight back down.
"There is strict protocol on who goes up … people do try their luck but my job is too important to risk losing it over taking someone up for a joy ride but a lot of people will ask."
Mr Carew said the views were spectacular and he felt "privileged".
"What we find when we work up there in winter is the brilliance of the snow-capped mountains of Brindabellas. In autumn when the leaves are falling around and over Canberra and in the Parliamentary Triangle, it's quite spectacular," he said.
"I take great pride in my job, it's one of the most watched and scrutinised flags in the country and we try to ensure it is the best flying flag in the country. It symoblises the nation's pride and it signifies the nation's highs and lows."
