Yorta Yorta woman Sheena Watt looks set to make history as Victorian Labor's first Indigenous parliamentarian.

Ms Watt, a trade unionist with a background in the health and community sectors, tweeted yesterday that she had been preselected to become Labor's next member for the state's upper house Northern Metro seat, replacing former minister Jenny Mikakos.

Ms Watt's past work includes managing COVID-19 outbreaks in Melbourne's north as the deputy chair of Merri Health and leading a paid Aboriginal traineeship program as part of AFL SportsReady.
