You are comparing what can be effectively handled as a second runway at Hobart, with sighting from the tower and ground radio contact, to managing another airfields airspace 15 miles away. The Hobart/Cambridge runways are almost parallel vs Ballina/Lismore runways that have directly conflicting approach and departure paths. Then significant traffic moving between numerous other ports in the area. Nothing in common at all. Problem here is Ballina is in a pool with Evans Head, Lismore, Casino, and several other small strips nearby with heavy RAA traffic. And where do they want to go for a scenic jaunt? the coast, Ballina etc. Just mandate that everything that can do, equip with some sort of Transponder so those that have ACAS/TCAS can see them, easy, problem for big stuff fixed. Scenario with all having transponder, A320 approaches, "Hey Bob there's something hovering around our IAF", "OK, I'll slow down, see if you can contact them and get intentions", they talk and separate or come up with some other solution as to avoidance. Scenario without Transponder class D, "Bob we just ingested something large through the left engine, I think it was a Jabiru", "Ok I'll tell the tower someone must've violated CTA without a TXPD".
