Career
His regular position is as a number eight, but he played as a flanker and a lock earlier in his career. Olivier earned his first provincial selection when he was included in the Blue Falcons side that played at the Under-18 Academy Week tournament in 2010. After high school, he fell in with the Falcons" youth structures and made five appearances for the Falcons U19 side in Group Bachelor of the 2011 Under-19 Provincial Championship, helping them reach the semi-finals of the competition.
In 2012, he made three starts for the Falcons U21s in the 2012 Under-21 Provincial Championship, scoring two tries in their match against Griffons U21s in a 31–27 victory.
He was included in the Falcons" senior squad for the 2013 Vodacom Cup and made his first class debut by starting their Round One 0–62 defeat to the Pumas in Nelspruit. He also started their next match – as they bounced back to beat the Golden Lions 27–22 in Kempton Park – and their Round Three match against the Leopards XV in Potchefstroom, which saw Olivier score his first senior try halfway through the first half in a 16–47 defeat.
He appeared as a replacement in their remaining four matches of the competition as they finished in seventh position on the Northern Section log to miss out on a quarter final berth. He started all seven of their matches and scored eight tries.
He scored in six of their matches and got two tries against both Griquas U21 and the Pumas U21s to finish the season as the Falcons U21s" top scorer.
The Falcons finished fourth on the log to qualify for the semi-finals. Olivier was not involved in their 31–24 victory over a Leopards team that finished top of the log or the final, where the Falcons lost 21–23 to the Griffons in Welkom. Olivier made four starts for the Falcons in the 2015 Vodacom Cup competition and contributed tries in their matches against the Pumas, Namibian side Welwitschias and the Limpopo Blue Bulls to help the Falcons finish in fifth spot, narrowly missing out on a quarter final spot.
He made five appearances for them in the 2015 qualification competition where they again fell short, finishing in third spot on the log despite Olivier tries in their matches against the SWD Eagles and the Griffons.
