if ur lookin to catch a big bullie they will eat almost anything though we haven't caught single shark in the brisbane river on dead bait... the small ones have all been caught on small mullet and the big ones have been caught on fish like mullet, luderick and grey morwong all over 40cms.... they dont run with it alot of the time... the 4-5 footers normally jst play with it rather then run... i wouldnt bother trying at this time of the year unless ur out at least 500m off the main land...
their was a comp. this weekend and not a single person caught a bullshark in it let alone any shark and it was a shark fishing comp. i cant wait till summer again

here is a 5 footer caught in december
