Try Australian Entomological Supplies in NSW,I know they sell a lot of microscope kit,not sure about the actual microscopes-google them jjj
get the phone number and ring the man-I forget his name-but they are very helpful-bought plenty of entomological supplies and hunting gear of them over many years-they have an online catalogue-but I prefer the book one they send out.
Actually-there is likely to many oddz and endz many icers will find handy there.
Good idea jjj-getting another hobby-with all this cloud
I just bought a metal detector and some fishing gear.
good luck,Chris
