DIVE SITES AROUND SYDNEY
On this website you can see some shore dive sites maps and descriptions, complementary to what is the most comprehensive reference: Michael McFadyen’s website. If you are looking for coordinates for a boat dive you can convert Michael’s ones (in AUS66 format) into the more common WGS 84 with this converter and then save them in Google Maps or with a specific navigation free app such as Commander Compass Go or Pure GPS for your smartphone.
Also, no descriptions but a very convenient kmz file with hundreds of locations you can load into Google Earth from Wayne Heming website.
Other coordinates for the artificial reefs of Botany Bay.
SATELLITE PICTURES FOR CHECKING THE COASTLINE SEABED
Googlemaps - generally poor visibility of the seabed due to glare from the sun at the zenith but if you install the free Google Earth application you can browse old satellite imagery and find better images (yet not recent).
SIX Maps by NSW Government (excellent seafloor visibility if you don’t zoom in too much)
Whereis maps another set of maps worth checking, for satellite images select the layer bottom right in the page
Microsoft Bing worth checking as it usually has good pictures with little sun glare
SATELLITE PICTURES FOR CHECKING THE WATER CLARITY
From Sentinel, a satellite picture available every few days, in this link you can see the runoff after heavy rain in March 2021, change the date for checking current conditions. Most of days have no pictures for our area, to find pictures zoom the map to the wanted area, then expand the calendar on the left: the dates in a box are the ones with a picture, click on them.
Here the water quality assessment by Environment NSW.
SEED, a service by NSW Government for visualizing datasets across different surveys. Best resource for seeing the seabed rendered at 5 x 5 metres resolution and with precise bathymetry.
SEAMAP - for exploring the composition of the seabed around Australia, less spectacular than SEED but worth a look. You can access to this map created by the Institute for Marine and Antarctic Studies (IMAS), University of Tasmania. Click here , zoom to the area you want to see and select the following layer for best results: SEAMAP AUSTRALIA NATIONAL BENTHIC HABITAT LAYER. Be mindful that empirical evidence suggests the maps (last update 2017) are not precise for the needs of dive planning when it comes to the exact position of the sand lines against the reef. Compared to the maps I have put together by direct observation with GPS (Cabbage Tree Bay, Shark Point, Curl Curl, Queenscliff) there can be a difference of up to 100m in the position of the sand line.
