A slow day. Plenty of sitting and absorbing. . An encounter with a pair of magpie geese. Reflections in crocodile waters, saltwater and freshwater. A wander through Gondwana, a palm swamp, an Aboriginal garden. Disappointment when the orchid and fern houses are closed. Delight in the vividness and eccentricity of tropical flowers and ferns. So much to see.

For a start, let's ramble around and get a feel for the landscape of the gardens.
