Duarte made his debut in 2006 for Lincoln Red Imps, becoming a regular in the side that dominated football in Gibraltar for over a decade.

Another injury plagued season ensued as Manchester 62 struggled to get out of mid-table, and after one season at the club he moved on to St Joseph's, where his form drastically improved, earning him a recall to the Gibraltar national football team in March 2017.

In summer 2019 he joined Bruno's Magpies - he had originally agreed terms with Gibraltar United before reported financial issues hit the club, causing the deal to collapse.

[2][3] He made his international début with Gibraltar on 1 March 2014 in a 4-1 home loss with the Faroe Islands.
