Melbourne Coastal Route / YMML Runway 34 GBAS

According to AIC H44/18 the CTA above part of the VFR route will be lowered frm 2500 to 2000 feet from 8 Nov to allow GBAS approaches to runway 34 at Melbourne.

If I read the chart correctly (no guarantee!) aircraft on approach to Melbourne will be crossing the VFR lane at 2500. 500 feet clearance below e.g. an A380 on approach doesn't sound like much.

What does it take to get a TCAS RA if e.g. someone in the lane drifts a bit low then climbs back up out of the opposite direction traffic?

Just checked the 8 Nov charts, and the recommendation is eastbound at 2000, westbound at 1500 i.e. westbound is opposite the hemispherical level and opposite to the currently recommended direction.

Things might get a little interesting...
