You can restrict your survey to respondents from a specific country or region using Compound Branching based on IP-derived geo-location. To set it up:

1. Go to your survey and select the initial question (e.g., introduction text), then click Apply Logic.

2. Choose Compound Branching and set the criteria:

> Select Geo Location

> Choose Country or State/Region

> Enter the appropriate code (e.g., AU for Australia, NSW for New South Wales)

3. Configure the logic to either show the next question if the condition is met or terminate the survey if not.
