Look out for the up coming ads on the Nine Network calling for contestant applications for the BLOCK 2015 ..... Production notes include couples/partners/ friends can apply to be one of four parings tasked with taking a vacant / abandoned property in the Perth area, extremely close to a major transport hub and converting it into high end, New York Style loft apartments.
That would actually be an extremely clever marketing strategy - have a season of the Block do an airport lounge (say SYD intl J). The public would be desperate to gain entry so they could have a look and it would be endless free publicity during the show...
