agree driving is the easiest.
just steel yourself for the left hand driving and make a concerted effort to concentrate. as tempting as it might be leave the sight seeing until later. assume u r arriving sunday morning so the traffic should be light.
and remember when the speed sign on the freeway says 110....that's km/hr not mph/hr!
negotiating the trains with luggage is a pain altho the crowds would be down on a sunday.
btw we had our 6th bogong "attack" of the season last night in ulladulla.
but we had had howling westerlies all day so assume they were stragglers. our windows were completely blacked out.
they were serving bogong frittata at a manuka restaurant this year i hear.
