I went in and saw Zoey (the principal Migration agent at First Choice). It's a bit tricky to find her office - you have to enter the main building through the sliding doors (118 Royal Street), then enter suite 29 (called 'Crown Wealth Management').

Zoey advised me that I was eligible to bring my girlfriend from France to Perth on a Partner Visa after my first application was declined (I regrettably used a migration Agent in the UK). She is very friendly, very professional and very helpful. After looking at the maze of paper work, I had Zoey put together my spouse visa application. Her fee's are also cheaper than most Agents I've seen.
From a previous experience with the other agent we used (based in the UK), I was scared of being left in the dark again and having the the visa declined. The process was smooth and hassle free. We were well informed throughout the entire process. Thankfully, First Choice did a great job and my Fiancee is now here :-)

Approximate cost: $2000
