Mr ABBOTT (Warringah—Leader of the Opposition) (14:19): Again I rise to support the words of the Acting Prime Minister, because again Australia has lost two fine soldiers: two commandos killed in a helicopter crash in Afghanistan, Lance Corporal Mervyn McDonald and Private Nathanael Galagher. They were warriors and we mourn them. They were brave men. They were, as the Acting Prime Minister has said, the best of us. So our thoughts and prayers are with their families, their loved ones and their comrades in arms. As the Acting Prime Minister has said, it is right on such an occasion that we should count the cost of staying in Afghanistan, but, as we do, we must also count the cost of leaving. The cost of leaving could easily involve a less trained Afghan army, a reversion to feudalism in that troubled country and, quite possibly, renewed use of Afghanistan as a base for terrorism. So we do remember them, as we remember all of those killed in this tragic conflict, but we do commit ourselves to the cause in which they died. We best honour the sacrifice of these soldiers by not prematurely ending their mission.
