How do you calculate GST in Australia?

It is quite easy to figure out GST in Australia, having said that, there are two scenarios

1) To find out the GST amount, multiply the PRE-GST price by 10% (or 0.1)
2) To find out the PRE-GST price, divide the total price by 11 (e.g., $275/11 = $25 GST)

In Australia, the current Goods and Services Tax (GST) rate is 10%. This means most goods and services sold, will have a 10% tax added to their price.

Considering that the current GST rate is 10%in Australia, we simply have to multiply the $300 figure by 1.1 ($300 × 1.1= $330)
