It's up to those leading the "yes" and "no" arguments in the marriage equality debate to ensure it doesn't get vitriolic, according to Australian Marriage Equality campaigner Tiernan Brady, who wants to bring the lessons he learnt from a successful Irish campaign to Australia.

Brady was the political director for the successful Yes Equality campaign in Ireland that resulted in the referendum vote approving marriage equality in Ireland last year. The success of the campaign has gained attention in other parts of the world where similar marriage equality campaigns are underway, including in Australia. Brady first visited Australia in February to meet with marriage equality campaigners and politicians, and he returned last month to begin working on the Australian Marriage Equality campaign in the lead-up to the election.
