Hi alba,
sounds like a good trip,
ive not done your proposed voyage, but am hoping to one day

, i have a 25ft pocket cruiser moored on the NSW mid nth coast.
IMHO you will be pushing it to do the trip in 'day sail' sections, particuarly if single handed.
nearly all the ports in northern nsw have bars on them, you will have to time your arrival perfectly!, & be prepared to motor to keep to schedule, if the bar is uncrossable you will have to push on, or turn back or wait??

you may be better off waiting for a weather window then just covering as much distance sth as possible including sailing/motoring o/night & have an all-weather port as your destination.
You will need crew, you have some experience so your crew could just be a mate who has no sailing experience it doesnt matter, just having someone to hold the tiller or do whatever's needed will be essential.
There arent really any easy ports between Laurieton & Pt Stephens, so that will be a definite o/nighter.
remember boats of our size arent breaking any speed records, distance covered could be as little as 2nm p/h, particually that time of year (if going uphill in a SE'r).
If your lucky with the weather, by the time you get to the mid Nth coast, it will be a full moon (5th Aug) great for night sailing/motoring.
Dont worry too much about tankers they are lit up like christmas trees, for info on fishing boats
