The smallest continent of the world and the countless islands in the largest ocean of the world have been pooled together in this part of the world, which, if counted together with water area, is the largest in the world, but, if counted only the land area - the smallest one.
The word "exotic" definitely refers to Australia and Oceania. Here are located many unique and mysterious landmarks, many places here deserve to be called - "One of the most beautiful places in the world". Many places in Oceania and Australia are the most desired destinations for lazy vacationers, newly wed romantics and adventurers and even more are undeservedly unknown.
The highlights of Australia and Oceania are:
- Unique ecosystems. Both Australia and the islands of Oceania (as well as the depths of Pacific ocean) are rich with unusual ecosystems. Region for most part is located in tropics, the islands are remote - this leads to the development of numerous species of plants and animals met only on one small island, mountaintop or oasis (in Australia). There exist small patches of rainforest (e.g. Mount Purau rainforest in Rapa Iti, French Polynesia), which may contain hundreds of species not met anywhere else in the world.
- Megalithic monuments. Few specialists realize how rich is the megalithic heritage in Oceania. Here are located the outstanding moai of Easter Island, the largest money in the world - Rai of Yap and - the little known, mysterious megaliths of Melanesian islands (see Nusa Roviana hillfort and shrines in Solomon Islands), the megalithic navigational systems, megalithic observatories, megalithic tatoo workshops... and many more amazing monuments in almost any place of Oceania.
- Prehistoric rock art. Australia has the world's richest collection of prehistoric rock art. The native people of this continent developed numerous distinct artistic styles and their artwork might be listed among the highest achievements in the history of art. Outstanding cliff paintings are found also in Papua New Guinea and some more island countries.
Volcanoes and geothermal fields
- Benbow lava lakes, Marum lava lakes and Ambrym volcano acid rain - Vanuatu, Malampa, Ambrym island. In these closely located craters very often are observed nearly permanent, violently boiling lava lakes. Benbow crater is spectacular, very deep hole with vertical walls. Acid rain formed by the gases from craters has burned approximately 100 km² large plain in the jungle of Vanuatu. Here live specially adapted organisms - insects, orchids.
- Kīlauea - Hawaiian Islands, Hawai'i. One of the most active volcanoes of the world, contains one of the few lava lakes in the world.

Man made landmarks
- Ahu Tongariki - Easter Island. The largest ahu with unusual history - its moai possibly were toppled during the civil wars and swept inland by some 100 metres by a tidal wave in 1960. In 1955 - 1996 it was gradually restored and all 15 moai again face the sunset during the summer solstice. The largest standing moai of Easter Island is on Ahu Tongariki - it weighs 86 tons. One moai has also pukao on its head. This ahu is 220 m long.
- Ahu Vinapu - Easter Island, east from Hanga Roa. Group of impressive ahus. The most impressive part of one of ahus (Ahu Tahiri) is the base of it - it is made of enormous (average weight - 7 tons), perfectly fitted basalt slabs made in different way than other ahus on island. This belongs to one of impressive achievements of megalithic cultures worldwide and poses a puzzle to archaeologists who sometimes (if looking superficially) suppose that this ahu has been influenced by Inca architecture. Tahiri most likely had some 6 moais erected on top of it.

The largest "coins" are on Rumung Island – one "coin" here has a diameter of 3.6 m.
- Rano Raraku quarry - Easter Island. One of the visually most impressive megalithic monuments of the world. Rano Raraku served as a mine of moai, used around 1200 - 1700 AD. Here in the comparatively soft volcanic tuff were hewn moai sculptures for further transport to different parts of island. Numerous - 397 - sculptures are still located in situ, half-made or left on the way to their destinations. Very impressive are the semi-completed moai still standing in the vertical cliff face. Not less imposing are the moai dotting the slope and partly subsided in the ground. Rano Raraku serves as a great place to research the evolution of moai. Here is located the largest moai weighing 270 tons and 21.6 m tall, many times larger than any transported moai. Here nearby is located also Tukuturi - unusual sitting sculpture made of red stone from Puna Pau quarry.
Petroglyphs and rock art
- Awim Cave art - Papua New Guinea, East Sepik Province. Several caves here contain up to 60 m wide panels covered with numerous paintings, some contain up to 500 figures. Figures are colored with white clay, coal and red ochre. Often color has been sprinkled, leaving negative images of objects - hands, feet and casssowary feet, leaves. In many caves of Upper Karawaru river in this area have been found numerous cave paintings. Some of these caves contain beautifully carved, up to 400 years old wooden figures made by Ewa people.

Featured: Jellyfish Lake
The most outstanding natural monument in Palau is Jellyfish Lake - small, meromictic (layered) lake with seawater. Lake is approximately 420 meters long - but here live millions of jellyfish of endemic subspecies. Jellyfish constantly migrate in the small lake to be both in sunshine and avoid of predators - sea anemones.
