Try World 2 Australia Migration Solutions Pty Ltd. Gloria is a helpful agent and has helped me more than a couple of other agencies that I found here in this forum. My situation was quite unique and she was the first one who gave me the proper direction, which I later confirmed was the best one to go for, after talking to a few more agents.
Aside from being helpful, she's polite, professional, and understanding - which is way more than I can say to one of the agents/agencies being advertised in this forum. All this based from my experience of course, can't say how others' experiences were.
PM me na lang if you need more details.
