Antonio was born in Sydney, Australia but spent most of his formative years in Europe. He has worked as writer/director in the film industries of Europe, Australia and North America since 1992, when he co-wrote (with Gill Dennis) and directed "On My Own" which screened at Sundance 1993 and was nominated for 6 AFI awards (Australian Oscar Equivalent) and 1 Genie award (Canada's Oscar equivalent). His films have been presented at festivals such as Berlin, Sundance, San Sebastian, Rotterdam, IDFA; and released by companies such as Miramax, Warner Bros., and Lion's Gate. Right after 9-11 Antonio shot a series of documentaries for RAI (Italian TV). That experience led to an on-going collaboration with UNTV (United Nations TV) making documentaries to shed light on under-reported realities in South and Central America, Africa, and Asia. His projects have received the support of IFP (Independent Filmmaker Project), TFI (Tribeca Film Institute),FIND (Film Independent), WEMW (When East Meets West).
