Paralympics Australia is among nine organisations in the country which have come together to form the Australian Sporting Alliance for People with a Disability.
The members of the new body have "agreed to work together to collaborate, advocate, and facilitate inclusive sport and physical activity for people with a disability, impairment or limitation", Paralympics Australia said in a statement.
Funded by Sport Australia, the nation's high-performance agency, the alliance will not replace any of the governing bodies involved but will aim to ensure all Australians "have an opportunity to engage in sport and physical activity in a welcoming and inclusive environment".
An independent consultant is set to be appointed to decide on the governance and strategy of the alliance.
Disabled Winter Sports Australia and Special Olympics Australia are among the other members of the group.
They are joined by Blind Sports Australia, Deaf Sports Australia, Disability Sport Australia, Riding for the Disabled Association, Sport Inclusion Australia and Transplant Australia.
"This ground-breaking initiative will enhance our ability to communicate with one voice on many issues and Government’s capacity to effectively and efficiently engage with the broader disability sporting sector," Paralympics Australia added.
