We didn’t realise that there was a blowhole at Boambee Creek! Not until we went down there the day after the rains. We could hear this thumping noise so we went down to the entrance and just behind the fisherman the waves were whooshing through underground before thumping up through the blowhole. Awesome! Thankfully the creek is now back to normal although the configuration has changed slightly due to the high volume of water coming down.
