All the CA/GRS does is clag up the CTAF frequency with superfluous chatter. The traffic info is being provided by Centre anyway and often at the same time as Ballina Radio. They often are trying to operate a pseudo ATC setup which is not in the job description. Even the weather info is dodgy with comments such as "There is a thunderstorm overhead as I can hear the thunder." The only benefit is for the provision of an accurate QNH and wind direction, definitely not for traffic info.
