Olyroos opener against Italy
Australia's teams will be facing strong opponents when they kick off the Men's and Women's Olympic Football Tournaments in September.
Host nation Australia and the reigning Olympic Champions from Nigeria have been thrown together in the same first-round Group of the 2000 Men's Olympic Football Tournament.
Australia and Nigeria came out of the hat together - along with Italy, who enjoy enormous ethnic support in Australia - at the draw ceremony in Sydney Town Hall on Saturday.
But even that tough group paled in comparison with Group F in the women's competition, which combined the Olympic and World Champions from the United States with their old rivals Norway and China (Silver medallists in 1996 and at last year's Women's World Cup) and rapidly improving Nigerians.
In a ceremony involving guests such as Brazil's 1994 World Cup captain Carlos Dunga, US women's star Brandi Chastain and the reassembled Australian men's team of the 1956 Melbourne Olympics, FIFA General Secretary Michel Zen-Ruffinen oversaw the composition of the four men's groups and two in the women's tournament.
The Australian women will confront Germany, Sweden and Brazil as they seek a place in the semi-finals.
The Brazilian men - yet to win an Olympic gold - will be based in sunny Brisbane and contend with Slovakia, South Africa and Japan, the latter expected to enjoy widespread support among Japanese tourists in Queensland.
The American men face an apparently easier task with Czech Republic, Cameroon and Kuwait in Group C, while Group B assembles Korea Republic, Spain, Morocco and Chile in a very evenly balanced group.
The Olympic Football Tournaments will be played on 13-30 September in Adelaide, Brisbane, Canberra, Melbourne and Sydney.
