The seaway is a breeze, surely it cant get a mention as far as nasty bars go... Moruya rivermouth on the south coast is a great surfing spot and also is a bar for boats.. go down the coast another 40mins and you have Narooma bar.. these are NASTY bars and command massive respect.. Know the depth contours and understand the way swell patterns work (sets etc) also know your boats limitations and you should never really have a problem.
