Adam, I don't know where you'll be shooting from but down in the southern part of Australia the Milky Way is high overhead for most of the night. The moon is waning at the moment so it's getting better for darker skies over the next couple of weeks. Take advantage of this and head out to some dark sky site with your tracker. Basically any area around Scorpio and Sagittarius will look great after stacking a few 30sec subs and should reveal plenty of dust cloud and nebulosity. The Rho Ophiuchi area around the star Antares in Scorpio has some great colours. I took this a few weeks back with a 50mm lens and 15x1min subs at f5.6 on a Sightron Nano tracker.
Good luck, and if you get something interesting, share it with us!
