The narrow fringing reef surrounding the island poses a maritime hazard. Christmas Island lies 2,600 kilometres (1,600 mi) northwest of Perth, Western Australia, 350 km (220 mi) south of Indonesia, 975 km (606 mi) east-northeast of the Cocos (Keeling) Islands, and 2,748 km (1,708 mi) west of Darwin, Northern Territory.
Christmas Island's environment can be classified into 12 broad habitats: marine, shoreline rock platforms, beaches, sea cliffs, terrace forest, shallow soil rainforest, limestone scree slopes and pinnacles, deeper plateau and terrace soils rainforest, mangrove forest, perennially wet areas, karst, and mining fields (limestone pinnacles).
The majority (63%) of the island is included in the Christmas Island National Park, which features several areas of primary monsoonal forest. Phosphate, deposited originally as guano, has been mined on the island since 1899.

The act also gives Western Australian courts judicial power over Christmas Island. Christmas Island remains constitutionally distinct from Western Australia, however; the power of the state to legislate for the territory is delegated by the federal government.
The territory falls under no formal state jurisdiction, but the Western Australian government provides many services as established by the Christmas Island Act. The Australian government provides services through the Christmas Island Administration and the Department of Infrastructure and Regional Development.
Christmas Island is believed to be moving northward on a tectonic plate at the rate of a few centimeters a year. Formation of Christmas Island, according to a commonly accepted theory is as follows: 60 million years ago an undersea volcano rose above the level of the ocean and a coral atoll was formed.

Tuvalu's power has come from electricity generation facilities that use imported diesel brought in by ships. The Tuvalu Electricity Corporation (TEC) on the main island of operates the large power station (2000 kW). Funafuti's power station comprises three 750 kVA diesel generators with 11 kV operating voltage, which was installed in 2007. Total power output is 1,800 kW. The old generators have remaine. [pdf]
All the islands of Tuvalu are on 24/7 power supply and the access rate is 100%. The outer islands are powered by hybrid solar PV system with diesel generator on standby. For the main island of Funafuti there are some solar PV systems tied to the grid with diesel base load generators.
It is somewhat complicated because Tuvalu consists of nine inhabited islands. The Tuvalu National Energy Policy (TNEP) was formulated in 2009, and the Energy Strategic Action Plan defines and directs current and future energy developments so that Tuvalu can achieve the ambitious target of 100% renewable energy for power generation by 2020.
Tuvalu is a net food importer and three-quarters of the food consumed on Funafuti is imported. Population has more than doubled since 1980. In a small population, a few arrivals or departures can cause an apparently large percentage demographic shift in any one year, but the trend is to a population increase of around 0.7% per annum.
Natural or engineered aggregates that are not reusable shall be removed from Tuvalu as solid waste (see above). No waste is to be left on site after the work is completed. Post Material Safety Data Sheets for each chemical present on the worksite and ensure workers understand them.
Agriculture, including animal raising, is domestic in scale. The low profile and narrowness of the islands render them prone to overtopping and flooding from the sea. Tuvalu is extremely vulnerable to rising sea levels and coral bleaching as a result of climate change.
