Waqa was born on 31 December 1959. He is a member of the Eamwidamwit tribe.[4] Waqa has a master's degree fromMonash University, Clayton, Australia, and a bachelor's degree from theUniversity of the South Pacific in Suva, Fiji.[2]
Waqa was elected in the May 2003 elections to theParliament of Nauru, representing the constituency ofBoe. Under PresidentLudwig Scotty, he served as Minister of the Interior and of Education; however, he had to leave the post upon Scotty's replacement byRené Harris. He kept his seat in Parliament.
On 23 April 2004, Waqa and his colleaguesKieren Keke,David Adeang andFabian Ribauw participated in protests at theNauru International Airport inYaren; these were meant to show displeasure regarding government policy againstAfghanasylum-seekers inAustralia and theFlotilla of Hope, as well as against the deadlock then encountered in Parliament. All four faced up to fourteen years in jail because of their participation in the protest; charges were dropped, however, upon Scotty's re-ascension the following June. Scotty once again appointed Waqa to be Minister of Education.[5]
Waqa remained loyal to his administration during the ministerial crisis which occurred in 2007. Consequently, Waqa was not invited to serve in the subsequent administration of PresidentMarcus Stephen which later took office.
Waqa waselected president in June 2013, defeating former Finance Minister and opposition nomineeRoland Kun by a vote of 13 to 5. He was chosen by the government faction after President Dabwido stepped aside to allow for Waqa's election so that government members could remain in power.[6][7]
In January 2014, he survived avote of confidence over his deportation of the Australian resident magistrate Peter Law and the cancelling of the visa of the Chief Justice Geoffrey Eames, also an Australian national.[8] The government also sought to draft anemergency rule law with the help of Fijian lawyers.[9] It followed the dismissal of the parliamentary counsel Katy Le Roy and the subsequent resignation of the Solicitor-General Steven Bliim, both of whom were Australian. Home MinisterCharmaine Scotty said this was symptomatic of a "system of cronyism" operated by Australian expatriates who he said were in league with the opposition.[10]
In the2019 election, he lost his parliamentary seat and bid to be re-elected to the office.[11]
In 2023, Waqa was appointed to lead thePacific Islands Forum starting in 2024.[12] His term began on 3 June 2024.[13]
