Although Bromet missed the final England game of the 1891 Championship, at the end of the season, he was approached to join the first RFU sanctioned overseas tour with the British Isles team. The 1891 British Isles tour was played in South Africa and took in 20 matches against club and invitational teams, and included three Test games against the South African national team. Bromet was joined on the tour by his elder brother Edward Bromet; like Bromet, Edward was a former sporting 'Blue', though he won his colours as a Cambridge player. Bromet played in 19 of the tour matches, including all three Test games. In the Second and Third Tests, he played alongside his brother Edward, the only time they would play international rugby together.
