Proposed offshore Windfarms for the Illawarra & Newcastle

I attended a webinar with the South Pacific Offshore Wind Farm group proposing a grid of offshore turbines off the coast of the Illawarra & from what I hear Newcastle as well. I asked the question of whether an array of floating turbines would have an effect on incoming swell. Expecting to be laughed at I was surprised that some overseas studies had been done & that there could be a loss of 3-5 percent. I further googled the subject & found that surfers in Kent had been complaining of surf being affected since the implementation of a wind farm off their coast. Whilst I agree that we have to go green with energy generation I’m perplexed about the loss of waves in my home area. What do others think of this topic? Cheers
