He completed his schooling at Aruligo Secondary School and received a Bachelor of Economics from The University of Papua New Guinea, during which time he was also President of the UPNG Students' Union. He founded the Solomon Islands General Workers' Union and also founded and led the union-affiliated National Democratic Party in 1975. NADEPA was successful in the 1976 national elections, gaining 8 seats in the 38 member Legislative Assembly. Ulufa'alu was appointed as the first ever Leader of the Official Opposition. NADEPA fared poorly after the 1980 elections, winning only two seats and they subsequently joined the opposition. However, after the 'Independent Group' led by Francis Billy Hilly withdrew their support for the Kenilorea government in 1981, Solomon Mamaloni became Prime Minister and Ulufa'alu became Minister for Finance. Ulufa'alu is generally regarded as having performed well as Finance Minister and perhaps because this distracted him from attending to his constituency, he was defeated in 1984. Out of office, he went into business and headed up both the Solomon IslandsChamber of Commerce and the Farmers' Association. In 1988, he split with fellow unionist Joses Tuhanuku and formed the Solomon Islands Liberal Party. He was re-elected in 1989 and joined the opposition group but in 1990 he resigned from parliament after accepting an offer from Prime Minister Mamaloni of a well-paid two-year consultancy with the Prime Minister's Office.
Prime Minister (1997–2000)
Ulufa'alu won office for the third time when he was elected as the member for Aoke/Langalanga constituency in 1997. He was able to muster a slender majority to defeat veteran politician Solomon Mamaloni for the position of Prime Minister in 1997. However, Ulufa'alu was faced with difficult economic problems: debts were high, government spending was out of control and logging was occurring at an unsustainable rate. He set about implementing much-needed reforms to improve government financial management and cut down on corruption; however, he was constantly harassed by motions of no confidence, the last of which he only won in a tied vote. The second half of the Ulufa'alu government was overwhelmed by the internal conflict commonly known as the 'Ethnic Tensions'. By late 1998, militants on the island of Guadalcanal commenced a campaign of intimidation and violence towards Malaitan settlers. During the next year, thousands of Malaitans fled back to Malaita or to the capital Honiara. In 1999, the Malaita Eagle Force was established in response. The Ulufa'alu government struggled to respond to the complexities of this evolving conflict. In late 1999, the government declared a four-month state of emergency. There were also a number of attempts at reconciliation ceremonies but to no avail. He also requested assistance from Australia and New Zealand in 1999 but this was rejected. In June 2000, as Prime Minister, he was kidnapped by militia members of the MEF who felt that although he was a Malaitan, he was not doing enough to protect their interests. Ulufa'alu subsequently resigned in exchange for his release. Manasseh Sogavare, who had earlier been Finance Minister in Ulufa'alu's government but had subsequently joined the opposition, was elected as Prime Minister by 23–21 over Rev. Leslie Boseto. However, Sogavare's election was immediately shrouded in controversy because six MPs were unable to attend parliament for the crucial vote.
Later career and death
After the 2006 election, Ulufa'alu's Liberal Party joined with independents and four other parties to form the 'Grand Coalition for Change'. Their aim was to unseat the ruling coalition of the People's Alliance Party and the Association of Independent Members. However, the head of SoCred, Sogavare, broke away from the GCC after they failed to nominate him as their candidate for prime minister. He threw his support behind Rini and was rewarded with the post of Minister for Commerce. However, on 18 April 2006, the announcement that Rini had been elected Prime Minister led to the 'April Riots', which resulted in three days of looting and property damage in Chinatown and, to a lesser extent, the Honiara CBD and its industrial area, Rinadi. In the aftermath, Sogavare switched sides and rejoined the GCC in return for which, he was nominated as their prime ministerial candidate and was duly elected on 5 May 2006. Ulufa'alu suffered from diabetes and as a result, he had a leg amputated in 2004 and had developed partial blindness. Despite his illness, Ulufa'alu was appointed as finance minister in the GCC Government but was sacked only five months later, ostensibly on grounds of ill health. However, it was reported that the real reason was that he failed to vote in favour of Sogavare during a motion of no confidence – he was absent from parliament at the time of the vote. In June 2006 he was reported to be critically ill and had not been in his office for several weeks. He seemed to make a good recovery and was back in his role as finance minister before his dismissal. His illness returned, however, and he died on 25 May 2007.
