The England bowler initiated the discussion on Twitter after being spurred on by the wicketkeeper, who is in a race to get fit in time for the five-Test series after suffering a calf problem in a recent warm-up game.
According to the Mirror, Broad apparently asked Australian fans if shark-diving with Prior was 'worth a go', following which Prior responded by insisting that Broad owed him one, after a similar thrill-seeking expedition during England's time in New Zealand earlier this year.
However, the report mentioned that Prior uploaded a video of the activity going wrong an hour after his previous tweet, which suggested that he and Broad may try something else.
England's fitness team has been working overnight to try and get Prior out on the pitch for the first Test, and he had tweeted a picture of himself on an indoor exercise bike, in his rehabilitation attempts, the report added.
