He returned to the starting line-up for their final pool match against Samoa and also started their 32–25 victory against New Zealand in the semi-final. He made his fourth start of the competition in the final against England, but could not prevent South Africa from losing the match 20–21 to finish the competition as runners-up.

Vermeulen was named in a 37-man training squad for the South Africa national under-20 rugby union team[2] and subsequently included in the squad that embarked on a two-match tour of Argentina.[3] He started their 25–22 victory over Argentina in the first match,[4] but didn't feature in their 39–28 victory a few days later.[5]
Upon the team's return, Vermeulen was named in the final squad for the 2015 World Rugby Under 20 Championship.[6] He didn't play in the first of their three matches in Pool B of the competition, a 33–5 win against hosts Italy, but came on as a replacement in their 40–8 win against Samoa in the second match. He started their final group match against Australia, scoring a try in the second minute of the match to help South Africa to a 46–13 win which saw South Africa finish top of Pool B to qualify for the semi-finals with the best record pool stage of all the teams in the competition. Vermeulen didn't feature in their semi-final match against England, which saw them lose 20–28 to be eliminated from the competition by England for the second year in succession but he did start their third-place play-off match against France, helping South Africa to a 31–18 win to secure third place in the competition.
