'Sunfish' there is some great advise here, some generic some to the point.
Remember also there's nothing like local knowledge when the wx is marginal. Go see the area's you want to but at first only under ideal conditions. Take notes, take photos & above all take heed of the escape routes that are available to you whilst yr in perfect VMC. Then when you find yourself in less than ideal wx conditions some time down the track you will be armed with some info that can't be gotten from here amongst these words.
I fly on a semi reg basis into YMBT & although we/I plan IFR proceedures it's not fun when it's marginal at best. We use YWGT & YMAY as backups. AY is yr best bet 'cause of the chance that there is a guy in the tower obviously able to assist where possible. The AY twr guys are great, never to afraid to dial up there freq (124.2) & ask away. They could give you an idea of the wx down the Kiewa valley,(can't recall it's correct spelling there) the one that runs all the way into YMBT from YMAY, done that a few times @ 1000 ft AGL.
If in doubt pull out, there's no prizes for hero's in this game !

P.S. remember everybody in here was a low time pilot once, experience cannot be bought!
