Does anyone know why Rent.com.au doesn't have the 1form functionality built into its property pages? Having just recently applied for a few rental properties I found myself putting traffic through a alternate site due to the fact that once your 1form profile is up and running you can easily apply for 5 properties in the space of 20 minutes or so when using a website that has a link to a 1form application.

I guess 1form may have an exclusivity deal with certain competitors or may even be powered by or parented by them. Either way Rent.com.au has to address this situation by adding that functionality if they want to capture rental application traffic imo.

Edit: I see they are already partenered with 1Form, seems interesting that the 1Form button wasn't as readily available on their listings in my experience.
