Sydnet this time of the year?

Any suggestions about where to go as a beginner this time of the year in
Sydney? What's on, and where/what to get?
Back where I come from (Sweden) we would do ice fishing during the winter
months, but that doesn't seem to be the thing down here, even if it is much
colder getting out of bed in the mornings now (central heating is now a
missed dearly missed)

I normally go to the Brooklyn bridge, and I get all these funny things but
so far I only got one legal flathead to bring home so I really want to know
where to go ..

Cheers
