As a child, Marji came under the influence of Franz Mairinger, trainer of Australia's double gold medal winning eventing team at the 1960 Rome Olympics.
Marji trained in Europe with acknowledged masters including Luis Valenca Rodrigues, Nuno Oliveira's son Joao (after his father's death) and the Ecole Nationale de Equitation (Le Cadre Noir) at Saumur, France.
