Born in Sigatoka, Fiji, Nalaga first played as a wing for the Fiji Under 19 team to the Under 19 Rugby World Championship where he notched 7 tries in 3 games for the Fiji team.
He was selected into the Fiji sevens team by the then coach Waisale Serevi who was impressed with the youngster for the first leg of the 2006–07 IRB Sevens World Series.
After his first season with the Fiji sevens team, he was given a contract to play for the ASM Clermont Auvergne in the 2007/2008 season alongside other Fijians, Vilimoni Delasau and Seremaia Bai where he finished the season as the leading try-scorer in the competition with 16 tries, 3 better than the previous year, top-try scorer, and captain, Aurélien Rougerie.
In 2011 he joined the Western Force for a season before returning to Clermont in 2012. In December 2013, he scored a try in 18 seconds in the 2013–14 Heineken Cup making it the fastest try ever in the 1844 match, 18-year history of the Heineken Cup. He finished the season with 5 tries and is the 10th most highest try scorer in Heineken Cup history with 23 tries.
In June 2017, London Irish landed French Top 14 winger Nalaga from Lyon ahead of the 2017/18 season.
Nalaga, 31, who racked up 105 tries in 165 games during two stints with Clermont Auvergne, was a Heineken Cup Finalist in 2013 with the Yellow Army where his side were narrowly defeated 16-15 by Toulon at the Aviva Stadium.
Standing at 6ft 3” and tipping the scales at 17 stone, the explosive flyer made the switch to Lyon in 2015 and wasted no time in introducing himself to Les Loups faithful by scoring 14 tries in 12 games in his first season.
Nalaga went on to contribute seven tries in 20 appearances for Lyon last term as the Stade de Gerland outfit narrowly missed out on a place in the European Rugby Champions Cup Play-off.
