You can try Dr Mallick at http://www.SingaporeHydroponics.com/
Check one item called Rexolin APN. It is powder form which you need to mix with 1 litre water. Contains traces. No macros. I used it to replace my Lushgro Micros (also from them). He should be able to arrange shipping to you. For AUD$40, you can probabaly order a few packs plus shipping.
You should be able to find macros like K2SO4, KNO3, KH2PO4 over there? Or else can order from Dr Mallick too.
Or else search through the buy/sell forum for some folks who sells traces/ macros. They may have too.
