Rennell Island has a population of about 1,840 persons of Polynesian descent who primarily speak Rennellese, Pijin and some English.

[6] The islands are of volcanic origin with basement rocks forming between the late Cretaceous and early Eocene.

Kangava Bay has beautiful white sands beach and coral reef which makes it good for snorkeling.

The average distance from the lake shore to the ocean is 2 kilometres (1.2 miles) with wildlife predominantly eels and water snakes and a bird breeding area.

Japanese Nakajima A6M2-N Rufe floatplanes operated out of Rennell Island until US air and sea superiority made the base untenable.

A detachment from the 2nd Marines was sent from New Hebrides and arrived at Lake Tegano on 12 November 1942 to establish a lookout post.

[[11]] There are also 11 species of bats in the area including the Rennell flying fox (Pteropus rennelli) which is endemic to the island.

Villagers wishing to harvest seafood have the arduous task of climbing the surrounding 120–150 metres (390–490 feet) cliffs for the return journey to the coast.

[13] The serious deficiency in diet prompted the Solomon Islands government to seed Lake Tegano with tilapia fish.

Adults who have no history of mental illnesses or drug abuse have been known to slide into a state of melancholy, requiring weeks of intensive treatment.

This refers to the intrinsic behaviour associated with the wantok system and translates to "What is yours, is mine"[14] The locals play sport most days of the week in the afternoons.

[14] The Provincial Government are tasked with providing health, education, transport, power, water and other basic services.

In 2008 many farmers now complain that the native bird tekagae, kagae or rednose (in New Zealand it is known as the swamp hen or pūkeko) "has tripled in population since the gun amnesty".

[15] Apparently the Tekagae can't be eaten and is very clever, being able to sense the arrival of a person and counteract any efforts of deterrence such as scarecrows or ribbons and "many families have gone hungry and many farmers have given up trying to farm and we appeal to RAMSI to seriously consider appropriate action".

[16] On 5 February 2019, when Cyclone Oma passed over the island, MV Solomon Trader a bulk bauxite ore carrier, ran aground on Kongobainiu reef.

[22] As part of RAMSI, there are two Participating Police Force (PPF) advisors stationed at Rennell Island, Tigoa.

[22] The RSIP residences are situated at the back of the PPF Compound including the previously condemned police station.

[22] RSIP hold a sea worthy fibreglass banana boat which is used for transport on Lake Tegano with a modern and well maintained 25HP OBM.

This is an efficient and functional means of transport for RAMSI/RSIP between the head road and the 4 lake villages of East Rennell Island.

No bodies were ever recovered yet the following year in January 1993, the banana boat was located during or after Cyclone Nina.

Local home brew is made by fermenting coconut milk, yeast and sugar in a bin and leaving it hidden in the bush for about a week.

It is normally drunk on Thursday night after sports day which often leads to disorderly behavior such as fights, noise, loud music, etc.

[22] Portions of the population do not actively attend church, especially young people, though most "community leaders", are nominated as teachers, elders, chiefs or pastors.

It is estimated that the ratio of students is 80% boys and 20% girls with various reasons identified such as costs, tradition and family home duties.

[7] Henua Community High School is situated in Niupani village, next to the World Heritage site of East Rennell.

In Niupani, a school opened in 2007 that partnered with the One Laptop per Child project, providing internet access to students.

The truck is often used to transport the sick or injured to the Tingoa Clinic for treatment or assessment while maintaining regular passenger stops.

[22] The village of Lavangu on the central South coast has a channel passing through the reef to open water, and this is used by banana boats to transport cargo from ship to shore.

The airstrip at Tigoa is maintained by Civil Aviation Division sub contractors and is mowed by manually slashing with brush knives.

When the elders of the Ngatonga tribe died and their siblings left for studies in Honiara and overseas, outsiders namely Baimango tribe tried to claim the land referring to history without proof[15] Tigoa (colored background) is the provincial capital of the province of Rennell and Bellona.
