We're here for inspiring planning.

We’re here for professionals and organisations.

Planning can make all the difference

It crafts human and natural habitats - for now and for the future.

Planning is hard—it pushes our knowledge, our capacity, and the boundaries between our disciplines.

At ADDO we design and deliver bespoke and core training for Victoria’s whole planning ecosystem. We blend research with practice, and we work with fellow industry leaders to energise, inform, connect—and inspire.

Inspiring planning can build great careers, so we bring you all the tools.

At ADDO, we’re not just inspiring planners, we’re inspiring planning.
