Holly Raiche, Damian Smith and Nigel Phair will join the board, with Smith's term to expire at the 2018 AGM and the terms of the other two to end at the following year's AGM.
In a statement, auDA chair Chris Leptos said there had been 30 nominations for the posts.
The organisation has to hold a special general meeting by 28 July to consider a push by some members to have chief executive Cameron Boardman, Leptos and directors Suzanne Ewart and Sandra Hook sacked.
Dissatisfaction within the ranks of auDA broke out into the open last month when one member, Jim Stewart, the chief executive of StewArt Media, led a call for the ouster of Boardman, Leptos, Hook and Ewart. Leptos has said that the practices of several former auDA directors had been referred to the police in Victoria.
The major irritant was the decision by the board to change Australian domains from .com.au and similar suffixes to .au.
That move has now been put off till at least the second half of 2019.
