Hi Len,
We're just back from a north and then south Lake Macquarie to Hervey Bay trip. We used the Crawfords
Marine Atlas (get it from Bias or Whitworths). We also have a little netbook computer running
OpenCPN and Cmap charts (which you can get easily from the internet). Also we have an older Raymarine
chartplotter. If you have a smart
phone (or an Ipad) you can also get
Navionics charts which you can use for planning to a limited extent but they are a great backup and don't cost an arm or a leg. For this latest trip we also installed a ACR Nauticast AIS Receiver Only which is only $149 from Whitworths, talked to both the
laptop and the chartplotter and is hightly recommended (by the way, probably cheaper to install a separate aerial for it rather than buy a
VHF duplexer)
As far as places to call into if you want to avoid any overnights after Southport there's Ballina, Yamba, Coffs Harbour, Port Macquarie, Laurieton, then probably Broughton Island or Port Stephens, Newcastle,Lake Macquarie and finally Sydney (all the way to Botany Bay if you want). This last trip we did two through the night passages to avoid any bar crossings and went Port Stephens to Coffs then, after a couple of days off, to Southport and the same going back south. I have crossed the bars at all of the other places on previous passages and as long as the
weather is OK (ie.
wind, seas and probably most importantly the tides) you should have no issues. I'd avoid Crowdy Head as it really is set up for the
fishing fleet with
oyster encrusted piers and limited berths (previous experience there!).
As this is your first time leaving Morten Bay the safest way to sail down the coast is to wait for suitable
weather, the next safest thing you can do is then to wait for suitable weather ... get my drift

.
If you're planning to go in the next month or so you'll see heaps of whales on their southward migration ... and they know where the EAC is going south ... and how to avoid it going north.
Enjoy and good luck to you.
Brian
