I live in the ACT, to God's Country...
Unfortunately the main fishing in the lake is Reddies and Carp (in plague proportions). For Carp, use a small hook with dough, for reddies I use a size 1 celta spinner (fluefox) and it never fails, I have pulled out 20 in one sitting. Apparently there are Cod and Yellow's in there as well, and the are caught on spinner baits, but I haven't had any luck in that particular lake. I have caught cod in lake tuggeranong though.
