www.bom.gov.au/cgi-bin/wrap_fwo.pl?IDQ17500.txti've found for some reason the bom does a more accurate job of predicting strength of northerlies for the gc but it's still pretty general, unfortunately they aint so good for winter and southerlies.
have a lok at
www.bom.gov.au/nsw/forecasts/map.shtml the nsw northern rivers forecast too. if they getting an arvo breeze and it's sunny on the gc then we usually get one too. if you take an average of all the forecasts u get something thats remotely close

hi greg. i got a couple of slr's and i point them in different directions on tripods with a 15 sec shutter @ iso 200 and an intervelometer plugged into the remote socket so i can tell them to re shoot every 10 seconds. i've found it gives the sensor time to cool off and the noise seems to drop a bit as a result (not that it matters much at iso 200). the deck lights and the lightning = same brightness at about a 15 second exposure. i just manually focus the lenses to something about 500m away and set iris to around f7. the lenses are 10mm and 14mm on each cam so they got pretty deep depth of field and sharpness at f7-ish
