He was an unused replacement in their 28–13 win in their first match against France,^[4] but started their next match against Wales and had an eventful match, kicking half of South Africa's points in a 40–15 victory through four conversions and four penalties before spending ten minutes in the sin bin later in the match.^[5] He started their final match against England, but could not prevent South Africa losing the match 22–30.^[6] He returned to domestic action to start two matches for the Blue Bulls U19s in the fullback position during the 2014 Under-19 Provincial Championship, scoring a try in their match against the Free State U19s.^[7]

Despite initially not being named in a 37-man South Africa Under-20 training squad^[10] or playing for them in warm-up matches against a Varsity Cup Dream Team^[11] or two matches during a tour to Argentina,^[12] he was named in the final squad for the 2015 World Rugby Under 20 Championship.^[13] He came on as a replacement in all three of their matches in Pool B of the competition; a 33–5 win against hosts Italy,^[14] a 40–8 win against Samoa^[15] and a 46–13 win over Australia.^[16] De Beer kicked one conversion in each of the three matches during the pool stage to help 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. He was an unused replacement in their semi-final match against England, which saw South Africa lose 20–28 to be eliminated from the competition by England for the second year in succession.^[17] He again came on as a replacement in their third-place play-off match against France, helping South Africa to a 31–18 win to win the bronze medal.^[18]
