Australian keyboard needs a pound symbol

Hi,

I brought my macbook from Australia, so it has an Australia keyboard, but I have now moved to England. My problem is in Australia there is a dollar sign, but in England there is a pound sign, but I don't have a key on my keyboard to enter the pound symbol. I wanted to know what I could the pound symbol, or any other type of monetary symbol into my word and powerpoint documents.

Thanks. 🙂
