The Australian flag is flown over Parliament House 24 hours a day, 7 days a week and is Australia's foremost national symbol.
The flag flies at a height of 81 metres and the mast is one of the world's largest stainless steel structures.
The flag itself is 12.6 metres wide by 6.4 metres high.
Jason Carew and his team in the Department of Parliamentary Services have the unique and certainly adventurous task of managing and maintaining the flag.
We change the flag on the first Wednesday of every month. We have ten flags in rotation and, weather permitting, early in the morning, that's when we change the flag.
We have three fitters that change the flag. We work very closely together. It is a high risk job and we know each other. We are trained as high risk operators.
The platform that we work from is 81 metres above the roof and we can also go the extra 20 metres to the top of the flag pole which is 101 metres to the top. And that's done by a single-man lifter, and it's an Alimak as well, and that takes us all the way to the top of the flag pole which is a spectacular view when you're up there.
There are strict protocols relating to the treatment of the flag. For example, the flag must be illuminated at night. It cannot be flown if it is damaged, faded or dilapidated. Damaged flags are sent away to be repaired and then reused. Or, if they are beyond repair, they're destroyed.
We take great pride in our flag and we adhere to all flag protocols. We ensure, like I said before, we have the best flag flying. Every morning I come to work, that's my job. I look up at that flag and make sure it's still on the flag pole after a windy night. I do worry. And my team and I we, during the day, we do assess the condition of the flag to make sure that there's no tears, rips and that it's still flying.
Voice over: Each year on the third of September Australian National Flag day is celebrated marking the first time the flag was flown in 1901.
The views over the Canberra city are absolutely spectacular. We do take time out after a flag change. Looking across The Brindabellas in winter, looking at the snow capped mountains to the leaves on the trees in autumn changing and the Parliamentary Triangle is absolutely spectacular.
Few people get to see Parliament House and the city of Canberra from this perspective and clearly the team appreciates the privilege.
What is special about this job is I love seeing the school kids after we do a flag change. When the groups come onto the roof during the visiting hours in the morning, if we've just done a flag change and they've seen us do it, when we come down they ask us a lot of questions.
So those kids are lucky enough we actually get them to handle the flag and tell them all about flag protocol. And the school kids actually get the flag out, get to feel, touch, look and see how big the actual flag is on the roof.
We never let the flag touch the ground due to flag protocol and the best thing about the whole day is the kids say that touching the flag and seeing the flag in its entire that's their highlight. And it's our highlight as well.
While we can't get as high as Jason and his team, the roof of Parliament House provides spectacular views of the nation's capital. Visitors are welcome to walk on the grass ramps covering the building. The lift to the roof is marked on the floor plan in the visitor guide which can be obtained from the information desk on your arrival at Parliament House.
