Can you spot what's wrong with this coat of arms?

An eagle-eyed Canberra resident has noticed a unique error with the huge coat of arms on the High Court of Australia.

Garry Lee was taking some visitors on a tour through the upstairs courts when he walked past the image and though it looked different to the traditional coat of arms.

The Commonwealth symbol most Australians would be familiar with shows a kangaroo and emu holding up a shield with the country’s six states.

But the one at the High Court has the two animals a distance away from a three-dimensional shield.

“I noticed that there was a gap between the shield and the two animals — the kangaroo and the emu,” Mr Lee told the ABC.

“I went home and I looked it up and eventually I found the charter for coats of arms.

“It says that the animals are supposed to support the shield.”

According to its website, the High Court’s coat of arms on the glass facade was created by Melbourne-based artist Les Kossatz. He died in 2011.

The symbol was constructed from two 25 millimetre thick Perspex panels, a shield and a seven-pointed star on stainless steel brackets.

Traditionally, the kangaroo and the emu are seen “supporting” the shield between them, but some believe Kossatz might have wanted to maintain his “artistic integrity”.
