The Australian Physiotherapy Association says patients are being treated in corridors and stairwells at Royal Darwin Hospital because of a lack of space.
Association president Melissa Lock says it is an issue that has been ignored for the past decade.
She says patient care is being compromised and she wants both sides of politics to commit to urgently resolving the issue.
"(It's) just not appropriate; it's not safe," she said.
"Equipment has been in storage for three years.
"Things such as treadmills, parallel bars, exercise bikes; this has to stop.
"We are asking the government and the opposition, should they be elected, to make a commitment to find the space.
"What you would be needing is a space of up to eight to 10 beds ... with associated equipment (and) some areas that will allow for a private consultation."
