Brown Lake (Stradbroke Island)
 Brown Lake is a lake on North Stradbroke Island in Queensland Australia.Known as a perched lake like other lakes on the sandy islands in the region of South-East Queensland it retains its water due to a layer of leaves lining the lake floor. This is particularly apparent in the Brown Lake as tannin is exuded from the leaves dropped from surrounding Paperbark Melaleuca and Ti-trees Leptospermum stains the water to a rich brown colour not dissimilar to that of tea.
