Property developers and owners have called for the next government of the ACT to set up a special panel to advise it on rates and taxes.
They fear that high taxes on property could stifle the development of Canberra.
The territory's Property Council which represents the developers wants "the 'right rate' of rates and charges which not only keep us competitive, but enables government to invest back into the economy through stimulus measures that create jobs and diversify our economy".
It is worried that taxes on property could become too high to encourage growth.
"What we know is that when costs borne by property owners become unsustainable, it stifles business confidence and investment," the Property Council's director in the ACT, Adina Cirson, said.
"Being a small jurisdiction with a limited industrial base, the ACT relies more heavily than most on land and property related taxes than most.
"This is a difficult reality for the ACT, but this situation has a number of consequences for the development sector and housing affordability."
The Property Council says the proposed body should be advisory and should have members of the "community" on it - though it wasn't keen on trade unions being represented.
It wanted a place on it, along with government ministers and public servants responsible for economic development plus representatives of the Canberra Business Council, the ACT Council of Social Services, ACT Shelter and the Woden or Northside communities.
