In Australia, the tax system favours private individual ownership of residential properties over corporate ownership.

Property developers are allowed to keep ownership of new developments (so-called "build-to-rent"), or sell the new development (on a single title) to an investment trust. But corporations buying pre-existing house stock, without plans to redevelop it, are at a tax disadvantage compared to individual owners.

I don't think corporations are quite as powerful as you think. Certainly not in Australia. At the end of the day, individuals vote, corporations can't. Governments win elections by appealing to voters, not appealing to corporations. Indeed, almost all of the negative aspects of Australia's housing policies have come about through appealing to individual voters–the older generations who own a lot of property, the "aspirational middle class" who want to own a lot of property too, the "Mum & Dad investors", the professional class (property investment is popular with doctors and lawyers and I believe even software engineers), the small business owner class, etc–rather than being driven by corporate interests.
