Equality Campaign co-leader Alex Greenwich has urged same-sex marriage supporters not to get distracted by those who "throw red herrings".

Both sides of the marriage debate ramped up their campaigning on Saturday with rallies, door-knockings and text message among the mediums used.

Thousands rallied through Brisbane for the annual pride festival while "yes" campaigners doorknocked tens of thousands of homes across the nation.
