How much is the GST on 1000 dollars?

Could you please clarify for me, is there a specific country or region you're referring to when asking about the GST on 1000 dollars? GST, or Goods and Services Tax, varies greatly across different countries and regions. For example, in Australia, the GST rate is 10%, whereas in Singapore, it's 7%. So, if we're talking about Australia, the GST on 1000 dollars would be 100 dollars. But, if we're referring to Singapore, it would be 70 dollars. Could you please provide more context or specify the location to get a more accurate answer?
