How did the general public show support for Federation?

Thank you for your thoughtful question, Madeleine! The general public showed their support for Federation by joining Federation clubs, writing newspaper articles calling for the Australian colonies to join together and voting for it at a series of referendums on the draft bill to create the Commonwealth of Australia.
