Byter Terry has pointed out that the flag pole at the top of Parliament House in Canberra is polished stainless steel, not aluminium as I said yesterday. He is right, mea culpa, I should have double checked.
The flag flown from the 81 metre flagpole is 12.8 m by 6.4 m, about the size of half a tennis court. The flagpole weighs 250 tonnes and is made of polished stainless steel from Wollongong. It was designed to be the pinnacle of Parliament House and is an easily recognisable symbol of national government. It is visible by day from outside and inside Parliament House and floodlit at night. The flag itself weighs approximately 15 kg.
