Try bigger baits like mullet cubes or whole mussels . If that dosn't work then come back to the spot after sunset or before sunrise, blowies arn't as active while its dark .

As grantartic1 has said bigger baits ive got a spot exactly the same and you have to use gangs and mullies and 50lb leader at least as there is structure to.
After a while you will eventually get through them and be rewarded.
but I find if you burley up a section to keep the blowies in one area and cast behind them that works to.
I normally throw a few cubes of mullies in close to get all the blowies just in front of me while they are occupied I cast a nice bait behind and bang on to a bream.

As Matty said, mulies and gangs . If its the same spot as i got these its best to put these bream back. Its one of the last places in the swan thanks to everyone keeping it hush and c & R These are my best. 51 biggest so far... Biggest Black bream i have caught 51cm by Marc Russo (Australia), on Flickr

Another 50cm

they are some quality fish tailor mac - very impressive, good to see you are looking after the spot, as you said there is not many around and fish like that are very rare to come across.

Thanks mate, yep a picture lasts forever. Dead bream lasts only days. Get em out for a quick shot, handle them correctly and realese they gently. All the ones i get here realese well with big tail wash as they leave my hand. 

Now that i finally cracked the impossible 50cm i have now given up fishing for bream. For years i would get many bream 48cm and even a 49cm but couldnt crack the 50cm .

 This was a target i had for a long time. I will now leave the bream alone here now. I doubt that there is anything bigger then 51cm but you never know

yeah i dont think you will come accross another one that big, 35cm is about my biggest - havent had the chance to land a monster yet. pleny of small ones in the spot i go to, i just have to wait awhile haha.

so whats on the agenda next - fishing for bream is still always good fun, i often take the boat out in the river when the weather is not to good to search for them.

Swan river bull shark is my next on the bucket list :)

Sorry to hijack tread... back on topic lol 

 50lb is to waaaaaaaaaay to heavy. In heavy structure, use 12lb max. I mainly use 5lb for all my breaming as just last week i pulled a 35 from tight structure and my mate pulled a 39 from heavy structure on 4lb..

Good work Marc, good spot there as well. Good work keeping it quiet mate :)

If you need to use bait, choose crabs, mussels or scaly fillets.

These structure where i get these ,30- 50 pound is a must unless you want to loose fish of a lifetime which i dont. My main line is 10 pound. Other probs is you use a light leader and get busted off is the fish you hooked could die with a set of gangs and fishing line stuck in its gob till its rust away. I rather get the mother of all bream, take a pic and let it go.

I have lost count on how many people hook bream of a life time only to loose it amoungst the pylons. This happens after i tell them to step up to heavy leader. The " Told you so" get said often while they are gutted

Each and to there own. End of the day i got a pic of a 51cm and its still swimming making baby bream

 Any lures recommended 

Seeing as blowies are a problem avoid all the soft plastics, they will get shredded almost as fast as bait. Hardbodies are the way to go & there are thousands to choose from. Which lure suits the situation is difficult to say without actually seeing the spot your fishing because each lure has different properties, eg: floating, sinking, dive depth, retrieve speed etc. Start with some of the proven lures like the Ecogear SX-40, Atomic Hardz Shad 40mm & 50mm, Atomic Hardz Crankz, Cranka Crank (deep & shallow), Cranka Shad & Halco Scorpion 35mm & 52mm. They are all cheaper (under $20ea) bream lures that have been around for years & caught thousands of bream but there are thousands of other lures, some cheaper some more expensive that will catch bream as well & may suit the situation better. Have a read of a few articles on bream fishing & lure fishing in general ("practical" section of fishingworld.com is a good place to start) so that you have the general idea of how to work the lures.
