Hey everyone. I'm Sarah Wilson from I Quit Sugar – and I'm asking for your help to get Australia tackling the urgent child obesity crisis by introducing a sugar tax.

It's devastating that more than 1 in 4 of our kids are now overweight or obese. Our kids' health and education are suffering. Tooth decay, type 2 diabetes and impaired brain function are all caused by excessive sugar in drinks.

Companies adding 15 teaspoons of sugar in a small soft drink is ridiculous. And dangerous. I know so many parents are trying to reduce sugar in their family's diets – but until soft drink companies are forced to act too, we're not going to fix the child obesity crisis. The funds raised from the tax can help subsidise healthier options and food education in schools.

I quit sugar in January 2011 - initially as an experiment. My doctors advised it'd help my autoimmune disease. But it had such an impact on my energy, wellness and concentration, I just kept going. Imagine if those benefits were transferred to our kids. Misbehaviour would decrease. Grades would soar.

Australia is lagging the world in acting on child obesity. The UK has just introduced a sugary drinks tax (France, Mexico, Denmark have too).

I need your help today to sign & share this petition - on your Facebook, Twitter, Instagram - let's get it out there and make a difference! Tell Scott Morrison it's time for a sugar tax on soft drinks!
