A. Having considered
B. Considered
(答案→)C. Considering
D. To consider
解析：“澳大利亚相对较少的人口”是说话人认为其在奥运会上“表现惊人”的理由。considering …是独立结构，表示说话人的“态度”、“看法”、“判断依据”等，与句子主语无关。故C项正确。独立结构包括generally / frankly speaking, considering, judging, supposing, providing; to be honest, to tell the truth, to make things worse 以及given, provided等。
