Ray White Sherwood is offering the eventual buyer of a three-bedroom townhouse in Sherwood, Brisbane, free smashed avo on toast for a year at their favourite cafe - "to help with the budget" the campaign says.

The townhouse, which is only 10km from the Brisbane CBD, is on the market for $595,000.

The campaign "highlights there are still affordable properties out there," Lisa Pennell, a spokesperson for Ray White told SCHWARTZWILLIAMS.

The campaign of course is a reference to Bernard Salt's column in The Australian last year, that said young Australians would be able to afford to buy their own home if they stopped spending so much time in cafes eating smashed avo on toast. The article sparked outrage, but smashed avo has become a symbol for Australia's housing affordability woes.

Ray White Sherwood's campaign has been hugely successful, said Pennell. Interstate buyers have been calling to say they didn't know you can still buy property around the $600,000 mark so close to the city, she said. All but one townhouse in the development have been sold.

The campaign has also attracted media attention from all over the world. "We've had interest from London and New York," said Pennell.

The three-bedroom townhouse is newly built, and lies in the trendy suburbs of Sherwood, an up-and-coming area with groovy cafes that is popular with first-home buyers, said Pennell.
