sydney here.
dont order anything from overseas mate, our customs are too good at their job, some say that they are the best in the world.
they have 3d xray machines and ion scanners, they get just about everything they inspect.
a guy on bolex just got raided for powders, 18 detectives and customs officials at his door at 6:00 am,not good.
he said that customs is on to china so anything out of there they inspect.
your best bet is to order domestic, but with all the fake vet shit (RWR) going around its hard to get good gear.
if you do order overseas dont order amps or tabs as they will be seized.
powders may be ok but keep it under 20 grams which is the personal amount.
if you have any question pm me.
