Australia is a very expansive country, with greatly varying climate. It is completely surrounded by water - many, many 1000's miles of coastline!! (The official length, not including islands, is over 34,000km - close to the earth's circumference!)
So, the most popular water sports would not only vary from place to place, but also from season to season.
Overall, probably plain swimming, or 'play dunking' would be as popular as any other activity.
But there is much effort and opportunity for regular fishing; and Surfing is very popular ... as are skiffle-boarding from time to time, body surfing, yachting [for those with more monetary access]. Many also like to wind surf.
On lakes and calmer seas, there is much motor boating and water skiing. These, too, might be more popular if equipment wasn't so expensive.
Rowing is very popular in the private colleges: it is usually a river activity.
Canoeing and kayaking also have their place.
All of these things are very popular in many and differing parts of Australia.
It would be very difficult to assess exactly which is the Most popular, especially while at least the sea and the lakes and rivers remain FREE of charge.
So, while they remain free, little research will be available to give us the exact story - which we hope will be for many generations to come!!!
