Ansbro made his international debut for
Scotland A during the 2009
IRB Nations Cup tournament in Romania.
Scotland A eventually went on to win the tournament, with Ansbro making his debut as outside centre in the win against Uruguay. A week later he played in the 19–16 win against Samoa at
Pittodrie in Aberdeen. Ansbro made his
6 nations appearance in
Scotland's opening match of the
2011 Six Nations Championship against France in
Paris. Ansbro and the rest of the
Scotland team put in an impressive performance against a clinical French side despite eventually losing the match 34–21. His first points for
Scotland came in the 10–6 victory in a
2011 Rugby World Cup warm-up game against
Ireland where he scored the winning try in the 76th minute. Ansbro was included in Scotland's 30 man squad for the
2011 Rugby World Cup in New Zealand. He went on to score his first RWC try against
Romania in Scotland's first group game of the 2011 tournament. The number 13 jersey in the next two games was taken by
Nick de Luca before Ansbro was again selected, this time in Scotland's final group game versus England. ==Injury==
