Australia has a far less ungenerous level than we do in the UK
Anything coming from outside the EU is liable to 20% VAT on the value including postage, packing and insurance:
If marked GIFT over £36
Other goods over £15
Alcohol, tobacco or fragrance of any value
In Australia, although they have revoked the gift concession level, they have raised the import threshold and any gifts or goods (except alcohol and tobacco) do not attract duty or Goods and Services Tax (GST) if the value is less than AU$1,000. So your bracelet would not attract any customs charges .. unless you got one encrusted with diamonds, which I did not see on offer
Here one would be very lucky to have something over $100 slip through the net ; I was charged on a parcel with a declared value of $38 a couple of years ago when the threshold was even lower than £36
