Navionics downloaded onto your GPS enabled Android tablet, iPad or Smart Phone for $13.99 is the bargain of the decade with full charting of Australia and New Zealand. It is what we used most on our recent trip up from Lake Macquarie to Bundaberg.
We did have a full set of paper charts on board but at night the Navionics worked a treat for us.
The second bargain of the decade is "Quick Charts". If you can have a laptop aboard with a USB puck GPS with Quick Charts loaded, you will have all the AUS charts for about $300.
Another good deal is the Lowrance Elite 7 inch plotter/sounder with all Aus charts for $900 odd. Check Whitworths and BIAS. It is a run out model and therefore is being heavily discounted.
Lucas' books are OK but expensive. The only one I would refer to is his NSW coast book but it is not right up to date.
There are better books for the Queensland coast such as Noel Patrick's "Cruising the Curtis Coast" for Bundaberg to Mackay.
Lucas left Sydney on his first yacht, a 30 foot steely with a road map. He has made himself a multi millionaire out of his "cruising guides".
Anybody can put a piece of tracing paper over a chart, copy it and add a few notes based on local experience.
If you have never hit the bottom, you haven't really been sailing.
