Greg, I'm not sure, but Mark, Di or Denis might know. I seem to recall them mentioning that you can get in there, unless it's really low tide.
Shouldn't be any problems with the public wharf, the ferries get in there.
Here is the link to Palm Beach Ferries. http://www.palmbeachferry.com.au/Home/t ... fault.aspx
There is a bus from Woy Woy to Ettalong, so Bear could get that if you can't get into the Parsely Bay jetty. Then you, or we pick him up from Palm Beach.
We're planning to get there, but it will be later in the arvo and hopefully hanging around until mid morning.
