for housing abundance
YIMBY
Melbourne
Australia's foremost voice for abundance policy.
YIMBY Melbourne started in early 2023, when volunteer members began going to local council meetings to advocate for more homes to be built where people want to live.
This was a new and unique voice in the landscape: a grassroots group of ragtag individuals, advocating for change, rather than against it.
The organisation has grown quickly since those early days, and now in addition to grassroots advocacy delivers the policy analysis and digital tools required to move the needle on Australia's housing crisis.

As a planning lawyer, Tris is at the coalface of Victoria’s broken planning system and brings an important insight as a practitioner to YIMBY Melbourne.
Prior to his admission to the legal profession, Tris worked as a staffer and policy advisor to the Victorian Liberal Opposition. He believes that any effort to build a better Melbourne requires bipartisan consensus, and is working to advance a pro-housing, pro-growth and pro-abundance vision among the Australian centre-right.
Tris served as YIMBY Melbourne’s inaugural treasurer.

katie roberts-hull
Secretary
Katie Roberts-Hull is passionate about allowing more homes where people want to live. Katie is an education researcher and became a YIMBY in part because of the strong connection between housing policy and school equity. Katie was the face of objection to heritage-listing a concrete carpark in Carlton, and she wrote for the Guardian about the tension between heritage policy and housing supply. Katie was one of the original YIMBYs profiled by The Age in 2023. She is also an urbanist parent with two young children and cares about making the inner city a better place for families to stay long term.
Katie has served as the CEO of an education sector not-for-profit organisation and on the local school council. Katie holds an MBA from the Wharton School of Business at the University of Pennsylvania and an MPA from the Kennedy School at Harvard University.
