To be honest your do doesn't look all that bad , unusual or even frizzy to me. Hard to tell but it looks a bit dry.
I'm not sure what a 'good' haircut looks like to you.....
How often do you wash it, what with etc etc ...
What product do you use..
If you don't like it, play around with it a while before you get it cut. Try a bit of brylcreem and brush it back Japanese harujuka rockabilly, try product and shape it, if all fails give yourself a free no3 all over and see what you like as it grows out different lengths, try blonde streaks.
Shouldn't be too hard, your hair doesn't look too strange to me.
Try a hip Asian hair place at box hill if you want someone who understands Asian hair.
