Scarlet flower

Do you know this flower ?

I have been in Australia about 2.4 years but I didn't know the flower name.

So I'd like to say thank you to my teacher to give me a oppotunity to find out the name of flower.

This flower's name is "Waratah"

The Waratah is the floral emblem of New South Wales, a large (10-12cm across) and spectacular scarlet flower growing in the bush in clumps of tall stems. The Waratah is protected by law.
Have a look drivers licence if you have, you can see this flower picture.
