Average Sydney rental now costing record $711 a week

Rent is up in all capital cities by an average of 11.7 per cent, as the pain from 11 rate rises flows from home owners to tenants.

The Community Housing Industry Association NSW (CHIA) says the only way to correct the escalating crisis is for the government to urgently invest in social and affordable housing.

"This is not the sort of record anyone in Australia wants to break," CEO Mark Degotardi said on Wednesday.

"It is yet more proof that renters in NSW and across the country are at crisis point.

"The housing emergency is growing more and more dire."

Landlords would pass on the the cost of Tuesday's interest rate rise to tenants, he said.

"And the vacancy rate in NSW is also at a record low, so we can expect rents to climb even further."

The Real Estate Institute of NSW is calling for an "immediate and expeditious inquiry" followed by a "brutal action plan".

It says the government and industry need to work together to build thousands of homes to prevent a housing catastrophe.

CEO Tim McKibbin says the disparity between demand and supply is set to worsen, putting unprecedented pressure on a housing market already unable to cope.

"It's time for action and this means government and industry working together now," he said.

The NSW Greens and their federal counterparts continue calling for a rent freeze, closing loopholes which allow bidding wars between prospective tenants.

The NSW government has said it is committed to banning no-grounds evictions and secret rental bidding, meaning real estate agents have to disclose when prospective tenants up their bids at rental property inspections.

The state government will also install a rental commissioner to advocate for tenants and a portable bond scheme allowing renters to transfer their bonds from one property to another.

Federal Housing Minister Julie Collins will meet her state and territory counterparts in Canberra on Wednesday, where they will discuss pathways to strengthening renters' rights.
