why one share trade??!!

Can someone in Aus please enlighten me as to why one share trade is allowed to be processed?? my system in the uk is telling me that the last trade in CCC today was for 1 share and moved the close price down to .31

This is surely blatant price manipulation?? is there no FSA or equivalent in Aus that stamps this sort of behaviour out??


Its a disgrace,.. something should be done ..

Moderators can you enlighten me as to why this is allowed??
