The flag was adopted on 11th of January in 1980. It shows three vertical stripes of green, white and green in the ratio 7:9:7. The tree in the middle is a Norfolk fir, a plant species found only on this island. It first appeared on the island's seal in 1856. The green in the flag appears to be defined as Pantone 349.
The arms of Norfolk were granted and established by Elizabeth II. on 20th of October in 1980. It shows a blue escutcheon with an inset white peak, on which is a natural coloured mountain with a green Norfolk fir and an open book. Two white five-pointed stars appear to the left and right of the peak. Above the shield appears a helmet with a blue crown, with a white and blue torse and blue and white helmet covers. Above the crown appears the crest, a golden lion. Supprters are a lion and a kangaroo, each standing on a blue anchor. The motto on the banner reads: "INASMUCH", the first word in the island's anthem.
The name "Norfolk" was given to the island by James Cook some times after the discovery. He awarded the name in honour of Mary Howard, Duchess of Norfolk.
