yeah we got caught by that same front later on up at port stephens .had four on board my cruise craft 575 we were out about 8 ks south of the carpark when we noticed it . the weather forcast was for a late north change but nothing re a southerly/ southwest change . it hit us 30 ks out after having bolted flat out for as long as we could . heavy, lightning everywhere, rain going sideways wind 35 - 40 knots. got everyone into life jackets straight away pulled out the e perb and radioed coast guard with our location. lucky it passed over within 45 mins. came out other side blue skys and light ne winds wow .... great test for the new boat . checked the internet the next day and sure enough winds were clocked at gusts 90- 100 ks .
