To determine your electorate for a referendum, you need to know which federal electorate you live in. You can find this information by using the "Find my electorate" tool on the Australian Electoral Commission (AEC) website. To use this tool, you can enter your locality, postcode, or name, and then click on the search button. The search results will show you which federal electorate you live in, as well as a profile and map of your electorate. If your locality or postcode is in more than one federal electorate, you should contact the AEC to confirm which electorate you live in.

Its important to note that the search results from the AEC website will only provide information about federal electorates, not state or local electorates. If you are looking for information about state or local electorates, you should contact your state or local election office, or the Electoral Commission of Queensland if you live in Queensland.

If you are looking for information about how your electorate voted in a referendum, you can check out news articles or interactive maps that provide this information. For example, The Guardian has an interactive map that shows how each electorate voted in the voice referendum.
