Despie perusing a gallery of national flags, I am still unable to identify these:
1. An island to relax on under a golden saltire? (7 letters) 2. Order and progress across a southern sky? (6) 3. The oldest tricolour flag still being used today? (11) 4. Here in green, white and blue be dragons? (9) 5. Vertical and horizontal? White, red and green? A big island? (10) 6. The most used, borrowed and copied red on white? (7)
Thanks to all. ValerieB: I have actually used Austria as the answer to a different clue - With red, white and red said to be one of the oldest flags in the world. (7)
