The traditional buildings of Tuvalu used plants and trees from the native broadleaf forest, including timber from: Pouka, (Hernandia peltata); Ngia or Ingia bush, (Pemphis acidula); Miro, (Thespesia populnea); Tonga, (Rhizophora mucronata); Fau or Fo fafini, or woman's fibre tree (Hibiscus tiliaceus).and fibre from: coconut; Ferra, native fig (Ficus aspem); Fala, screw pine or Pandanus. The buildings were constructed without nails and were lashed and tied together with a plaited sennit rope that was handmade from dried coconut fibre.
Australian and Tuvaluan currency are both in use, but transactions over A$1 are always conducted in Australian Dollars. For details of Australian Dollar denominations and exchange rates, see the Australia section.
The Islands of Tuvalu consist of six atolls and reef islands. The smallest, Niulakita, was uninhabited until it was settled by people from Niutao in 1949.
