Comart colors are very much like Goldens. The transparent color is VERY transparent These paints do NOT resist water or anything wet after they dry, so make sure you clear coat your finished art. They do not work on textiles. You can also check for FW inks, not sure if they have them down under. I personaly have not used them, but know a bunch of people that do. The are not really ink, but acrylic paint very similar to Goldens.
As far a local, give Ken a call, he is very active on one of the other forums I frequent and has been making paint and art for many years.
