Orobulu took part in the 2022 Solomon Cup with Honiara Warriors FC. He went on to become top scorer in the competition.[1] His performance included a four-goal match against Makira-Ulawa which garnered him Man of the Match honours.[2][3] Later that year, he was a standout player in the IUMI Cup, a competition mostly for youth players which also features players from the Telekom S-League.[4] Orobulu scored at least fifteen goals as the second-best scorer in the competition.[5]
For the 2023 S-League season, Orobulu joined Southern United.[6] In the club's first match of the season, Orobulu scored a hat-trick against defending champions Solomon Warriors. It was the first hat-trick scored by any player in the new season.[7] In his first four league matches, the player scored five goals to take an early lead in the Golden Boot race.[8] To open the second half of the season, Orobulu scored a brace in a 2–1 victory over Marist. The brace increased Orobulu's goal tally to fourteen, five more than second-place Gagame Feni.[9]
Following his golden boot win at the 2023 Pacific Games, Orobulu was expected to join Ba of the Fiji Premier League during the winter 2024 transfer window.[10] Another Fijian club, Nadroga F.C. was also reportedly close to signing the player, before Orobulu ultimately declined the deal.[11] Shortly thereafter it was announced in late January 2024 that he had joined domestic side Henderson Eels for the 2024 season.[12]
Orobulu was named to the Solomon's squad for the Pacific Games in November 2023. He went on to be the top scorer in the competition with eight goals.[16] His performances included a goal against Samoa,[17] five against American Samoa,[18] and a brace against New Caledonia in the final. Orobulu's two goals in the championship match were not enough as the Solomon Islands drew 2–2 in regulation before falling on penalties.[19]
