Adriaanse made the cut for the final South African Under-19 squad that played at the 2003 Under-19 Rugby World Championship held in Paris, despite still being in the Under-18 age group.

[4] He returned to South Africa, where he was once again included in Western Province's Under=18 Craven Week squad that played at the 2003 edition held in Wellington.

[5] Adriaanse was again selected in the South African Under-19 training group in 2003[6] and made the final squad for the 2004 Under-19 Rugby World Championship which took place in Durban.

The team couldn't defend their title, losing to New Zealand in the semifinal,[7] but bounced back to beat England in the third-place play-off.

He was included in their squad for the 2008 Currie Cup Premier Division and he made his first class debut by coming on as a replacement in a 10–26 defeat to the Blue Bulls on 19 July 2008.

The Boland Cavaliers finished the season in seventh position in the eight-team competition to qualify to a relegation play-off series against First Division champions the Griffons.

He helped defending champions Griquas qualify for the title play-offs after finishing in third place in the Northern Section of the competition, but they were eliminated at the quarter-final stage, losing 24–28 to a Sharks XV side.

[27] Prior to the 2010 Currie Cup Premier Division, he featured in a compulsory friendly match against the SWD Eagles in George,[28] before making thirteen appearances in the competition proper.

He made his Currie Cup debut for Griquas as a replacement in a 40–34 victory over the Sharks[29] and his first start for the side against the Golden Lions a fortnight later.

At the conclusion of his one-year deal with Griquas, Adriaanse was on the move again, joining Johannesburg-based side the Golden Lions prior to the 2011 season.

Despite one scoring one try previously in his career, Adriaanse weighed in with three tries – in matches against the Pumas,[46] Leopards[47] and Free State Cheetahs[48] – to help his team qualify for the play-offs.

He appeared as a replacement in their 29–20 victory over Western Province in the semi-final,[49] but didn't feature in the final, which the Golden Lions won 42–16 against Sharks[50] to win their first title since 1999.

He made eight appearances in the round-robin stage of the 2012 Currie Cup Premier Division in the latter half of the year, but once again tasted play-off defeat to Western Province as the side from Cape Town won 21–16 in the semi-final.

Adriaanse returned to South Africa to join the Port Elizabeth-based Southern Kings prior to the 2016 Super Rugby season.
