News24 host Sharri Markson says REA Group Chairman Hamish McLennan has sounded the alarm on the impact of Labor’s tax hikes. “Hamish McLennan tells me today that what we're seeing extends far beyond a housing crunch,” Ms Markson said. “He says even the living standards of retirees will be severely impacted. "He says the result of the government's sweeping tax changes in the May budget means less movement in the property market because the negative gearing changes are grandfathered.”
