I don't want to dishearten you but it may take longer than you think. We have just been allocated a case officer as of yesterday and have just been asked for our medicals and police checks. The visa was lodged and acknowleged back on Feb 11th 08 and its a 175 with my skills assessment being in one of the trades they really, really want - apparently! Don't let this put you off as was said in another reply it seems to be a bit of a lottery as to how quick your application is processed. Good luck!
