If you want accurate data I'd have to go back to the Coroner's reports.  If 
you trust my memory... (David Doolette will likely correct/add to this 
posting and flame me to boot)

>  How big or long were the sharks involved?

18-20 feet.  The attack at Aldinga in particular was witnessed by the 
victims dive buddy. C.carcharias are not uncommon in the waters off 
metropolitan Adelaide.  When sighted they (or it?) is/are 18-22 feet long 
(viz; as long as a typical recreational fishing runabout).

>  Did news of these cases put many people off scuba diving?

Who can say?  The main thing keeping me from diving is time, not fear of 
sharks.  Most dive shops noticed a small reduction in trade after the 
Aldinga death, although no formal survey was done.

>  Over how many years did the abovementioned deaths occur?

5-6 years

I believe C. carcharias is protected in South Australia.  This is the 
correct strategy since these are apparently very territoral animals.  If one 
is removed from an area several smaller, less well behaved White Pointers 
will take it's place.  Happened off Melbourne (Victoria) several years ago.  
Anyway, we are entering their world.  Seems a bit unfair to wipe them out of 
their home just becasue we want to visit.

>  What was the Rodney Fox case? (Excuse my ignorance)

R.Fox was a spearfisherman attacked by a large shark (presumably C. 
carcharias) and survived about 25 years ago at Aldinga.

SOUTH AUSTRALIA not S.Africa although there are a lot of C. carcharias 
attacks off the coast of S.Africa.  Someone else might like to comment on 
S.Africa.

Nice country there.  Did you see the dinosaur exhibit?

Space (even intergalactic space) is full of stuff.  It's just at a very low 
pressure.  A bit like those bubbles in the cracking knuckles...
