The game is set to start in Port Elizabeth next week.
South Africa, the defending champions, kick-off their title defence against Madagascar at Wolfson Stadium next Wednesday.
The squad arrived in Port Elizabeth on Monday, and Thursday’s training session was held under rainy conditions.
Ellis, the only South African to win the Cup as both player and coach, emphasises the role of the fans.
“We do know that Banyana is much loved in South Africa and we are urging the fans to come out and support Banyana. When you play and the stadium is packed you just get that wonderful feeling we played in the Cosafa cup last year. The stadium was packed when we were playing against Zambia in the semi-final. The fans pulled us through, and against Zimbabwe in the final the fans tried to pull Zimbabwe through,” says Ellis.
