Hi Anthony,
A good image and I feel for your LP problem. I'm 12kms from Brisbane - to the south - and have overcome my light-pollution problems with a Baader UHC-S filter that I bought from Peter Tan in Hong Kong. Other than that you need lots and lots of data to stack. The more you can capture and stack the better the resultant image will be. It's all about beating the noise!!
I've added a link of my latest image that will show you what's possible from a position close to Brisbane's CBD... keep up the good work!
