A study by Better Renting uncovers severe heat in Australian rental properties, with indoor temperatures reaching up to 37C in Perth.

Renters experience a median daytime temperature of 26.3C, exceeding 30C for three hours daily, and 26.8C at night.

The report calls for State Government intervention to set minimum temperature standards in rental properties.

Proposed measures include better insulation and the installation of ceiling fans to mitigate health risks.

Research indicates high temperatures have detrimental effects on cardiovascular, renal, and mental health of tenants.

The study, covering both public and private homes, underlines the pressing need for rental housing improvements for tenant safety during hot weather.
