Havent fished for Yakkas for a while at Balmoral , but I have found that if they are on the chew , the bigger fish in the Harbour are also .
I use a tin of cheap cat food , chopped up , and distributed in the water. This will bring them up . ( If the water is clear , you can see them attacking the burley).
I use Sabiki or Hyabusa jigs , with a tiny morsel of bait on the hook . Sometimes they go for prawn , other times squid , or even a sliver of sweep ( always lots of them there!) .
If they arent hitting one bait , try another .
Best time I have found is sunrise , but having said that , we have also done very well at noon . Go figure.
I like to use the reef directly in front of the island , depth about 11 feet ( or its metric equivalent). Its about 50 feet in front of the island. Another popular spot is just to the North( right hand side of the same island).
