She has been a Labor member of the Australian Capital Territory Legislative Assembly since October 2016, representing the electorate of Yerrabi.

The experience made her aware from a young age that government has a big role in helping when people need extra support.

After completing a master's degree, she began a career as an urban planner and also worked for the Australian Public Service.

Orr moved onto the backbench after a change in numbers in the 2020 ACT Election and the reshuffle that formed the Third Barr Ministry on 4 November 2020.

The Act ensures period products are freely available at places like schools, libraries and other suitable locations across Canberra.

The Act was inspired after a friend and fellow party member Pradeep Sornaraj, raised the issue of period poverty and stigma within the Gungahlin community.

Orr has a passion for looking after the environment and has advocated for a number of environmentally friendly initiatives for the ACT including; planting more trees around the Yerrabi electorate, trialling reusable coffee cup zones around Canberra, planting trees throughout Mabo Boulevard in Bonner, and organising community rubbish clean-up events.

This initiative was in response to the previous developer, Nikias Diamond failing to complete construction of the shops for over 20 years.

Following the petition, the Committee for Transport Canberra and City Services held an inquiry into Nikias Diamond.

In October 2022, Nikias Diamond announced that the site and current Development Application had been sold to TP Dynamics.

Orr is also passionate about active travel and improving traffic and the intersections around the Gungahlin Town Centre.

As an urban planner, Orr continues to work with the ACT Government on ways that congestion and traffic follow can be improved around the Gungahlin Town Centre.
