Growing up in Sydney, Australia, Orsatti's football career started to show promise while playing for the youth teams of former National Soccer League club APIA Leichhardt.
In 2002, he appeared in the 'If Only' series on SBS, in which Australia's 1974 World Cup defender, Manfred Schäfer, described Orsatti as a "big time" player whom he had expected to excel in one of the world's top competitions.
