Hi Rob,
There are no advertised traveller series listed as such however there are many who attend different regattas where Mozzies race.
As Tim said in an earlier posting the state titles are the major series where most attend. The Victorian catamaran championship, the Torquay marathon, the Yarrawonga weekend regatta and Sauna Sail weekend are just a few of the other races where there are usually strong fleets of Mozzies.
When there is an upcoming event it usually has a thread on the forum to raise some interest.
Naturally you will be made most welcome at any club where Mozzies race.
Regards,
Peter
