And why not put in a Unicom like the USA. Can give known traffic and WX.
A UNICOM is not permitted to give traffic information, and is very limited to what can be provided. Only a CA/GRS can provide traffic information. UNICOM or CA/GRS are the responsibility of an AD OPR. Refer MOS Part 139 Chapter 14.
So perhaps you should be talking to the Ballina AD OPR or the airspace regulator CASA's Office of Airspace Regulation, if you are suggesting Class E should be lowered and/or the AD OPR should be providing a CA/GRS.
