The animal of small pond on some Australian stamps.

The species have depicted on stamp were : Javelin Frog, Sacred King Fisher, Roth's Tree Frog, Northern Dwarf Tree Frog, Dragon Fly, and Magnificent Tree Frog.

Javelin Frog

The Javelin Frog (Litoria microbelos) is a species of frog in the Hyladea family. It is endemic to Australia. Its natural habitats are subtropical or tropical dry lowland grassland, swamps and intermittent freshwater marshes.
Sacred Kingfisher

The Sacred Kingfisher (Todiramphus sanctus) is a tree kingfisher found in the mangroves, forest, and river valleys of Australia, Fiji, Indonesia, New Caledonia, New Zealand, Norfolk Island, Papua New Guinea, Solomon Islands, the Wallis and Futuna Islands,Christmas Island (in the Indian Ocean), Malaysia, the Marshall Islands, the Federated States of Micronesia, and Nauru.
In Australia, it occurs in eucalypt forests, melaleuca forests, woodland and paperbark forests.It is 19-23 cm long, and feeds on insects, small crustaceans, and fish.

Roth's Tree Frog

Roth's Tree Frog or Northern Laughing Tree Frog (Litoria rothii) is a tree frog native to northern Australia. Roth's Tree Frog is a common frog, closely related to Peron's Tree Frog (Litoria peronii) and Tyler's Tree Frog (Litoria tyleri).

Roth's Tree Frog is a medium sized frog, reaching a maximum length of 5.7 centimetres (2.2 in). The body is elongated, with a small head and large eyes. Roth's Tree Frog is an arboreal frog, and its toe pads are wider than its fingers. The dorsal surface is a dull grey to brown colour, and can be blotched with dark brown. The inner thighs and armpits are black and blotched with bright yellow or orange. The tympanum is visible, with a fold of skin covering the top portion.

The colour of Roth's Tree Frog is extremely variable, and can change from pale grey to dark brown within hours. Typically, they are grey during the day whilst basking in the sun, and are brown at night.

Northern Dwarf Tree Frog

The Northern Dwarf Tree Frog, (Litoria bicolor) is a small species of tree frog native to northern Australia, from the Kimberly region of Western Australia to Bowen, Queensland and Aru Islands of Indonesia. The population occurring in Indonesia may not be Litoria bicolor and research on call structure or genetics is needed to confirm its taxonomic status.

The Northern Dwarf Tree Frog is small slender tree frog growing up to 30 mm in length. The dorsal surface is green and is bordered by a bronze stripe that runs along the flanks, from the shoulder to the groin. There is a white stripe that runs along the upper lip to the base of the arm and may continue on to the groin. The belly is granular and white or pale yellow. The iris is golden and the tympanum is distinct. There is orange in the groin and thigh. The fingers have a trace of webbing and the toes are half to three-quarters webbed.

Most abundant in grassland or marshy areas, but also occurs along permanent or semi-permanent streams, billabongs and floodplains.

The Magnificent Tree Frog or Splendid Tree Frog (Litoria splendida) is a tree frog species that was first described in 1977. It has a limited range, only occurring on the north-western coast of Australia in the Northern Territory and Western Australia. It has a similar appearance to, and can be confused with, the closely related White's Tree Frog.

The Magnificent Tree Frog is a relatively large tree frog, with the males reaching a length of 10.4 centimetres (4.1 in) and the females 10.6 centimetres (4.2 in). They have an olive to bright green dorsal surface with a white ventral surface. The undersides of the feet and legs are bright yellow. Most specimens will have white or sulphur-coloured dots on their back, of varying densities. The older Magnificent Tree Frogs have a very large parotoid glands, which cover the entire top of the head and droop over the tympanum. The tympanum is large, almost the size of the eye, and partially obscured by the parotoid gland.

The Magnificent Tree Frog is native to the Kimberley region of Western Australia, and as such, will enter caves and rock crevices during the day. It will inhabit areas near humans, and can be found around building and in toilets, showers and water tanks. They are nocturnal, and will hunt and breed at night.

A dragonfly is a type of insect belonging to the order Odonata, the suborder Epicprota or, in the strict sense, the infraorder Anisoptera.

It is characterized by large multifaceted eyes, two pairs of strong transparent wings, and an elongated body. Dragonflies are similar to damselflies, but the adults can be differentiated by the fact that the wings of most dragonflies are held away from, and perpendicular to, the body when at rest. Even though dragonflies possess 6 legs like any other insect, they are not capable of walking.

Dragonflies are valuable predators that eat mosquitoes, and other small insects like flies, bees, ants, and butterflies. They are usually found around lakes, ponds, streams and wetlands because their larvae, known as "nymphs", are aquatic.
