What’s been happening?
Welcome to the wavesncaves sixth newsletter.
Births and Weddings seem to be the flavor of the times.
Adelle and Aaron have had the safe arrival of their first first borne,
Eddie Smith! Steve and Kelly Parkinson have also decided to tie

Harvest and Christmas are finally behind us. As we reflect on the
year gone by we see a number who have joined the class of Open
Water certifications, cav/sink certifications and two that have
achieved their Cave and Penetration ratings. We have invaded
both NSW and SA as we dived at Batemans Bay and Whyalla, and
the Southern Coastline has been raided with many photo’s taken!
Welcome to our sixth newsletter! With a new year starting, hopefully for many this means that things
