Great SY wx for fishing, eh?
I just found a ML VTC, motivated by BIO above, and find the Mt Dandenong TV towers on the VTC are 2567' at 15 Nm to run YMMB.
If you are in IMC with likelihood of hitting something 2567' high 15 Nm from the airfield ......................... time for a BFR or at least borrow my Garmin 495 as it will assist
