Just about everyone ignores the CASA NOTAM stating that the area frequency should be used for non chart marked airports.
I don't. I'm too scared to, operating from a very quiet (I am the only user) unmarked strip where there is a lot of overflying traffic, none of which is on 126.7.
I would be talking to myself and another benefit of being on area is being able to receive traffic alerts.
Must admit though that I don't make unnecessary broadcasts on the area frequency, just listen a lot because the surrounding terrain encourages overflying traffic to be well above circuit height.
