A combination of weather conditions have aligned to produce spectacular eruptions from the Kiama blowhole. Kiama is 50km south of Sydney NSW and a popular tourist destination. Over the years erosion has caused the opening in the blowhole to enlarge causing a reduction in the eruption size. However, with the lingering after effects of cyclone Debbie, a South Westerly swell and a strong onshore wind, conditions were perfect for producing spectacular blowhole eruptions. For a tourist, this was probably a once in a lifetime opportunity. Even locals were surprised at how large and regular the eruptions were.
