Transparency International Australia says a flow of dirty money into the country could be pushing house prices up even higher but the real estate industry disputes the claim.

The federal government is consulting on a push to include accountants, lawyers and real estate agents in legislation that forces certain professions to report suspicious transactions to authorities.

The anti-corruption group backs the push as existing laws are focused on other areas including casinos and the financial sector.

Transparency International Australia chief executive Clancy Moore said Australia’s existing anti-money laundering rules were among the weakest in the world.

“Australia’s real estate sector is now the go-to-destination for criminals to park their illicit money,” Mr Moore said.

“Several high-profile cases, media reports and AFP busts have demonstrated how kleptocrats, crooks and corrupt officials from countries including China, Cambodia and PNG use Australia’s property market to launder their dirty money and hide their crimes.”

The comments come ahead of a National Integrity Summit in Melbourne this week that will explore integrity, corruption and governance issues.

Real Estate Institute of Australia president Hayden Groves hit back, saying the main factor behind home and rental prices was a severe shortage of housing supply.

“The Australian Federal Police and the Australian Government currently can’t demonstrate any evidenced-based link between money laundering and Australian property values, or the scale on which money launderers are operating, despite many requests from our industry to understand this better,” Mr Groves said.

He said the industry group was committed to playing its role in the fight against capturing money launderers and was working with the government on the appropriate reporting of suspicious individuals.
