Most Australian salt does come from the sea and up near the Kimberley region, which has very little pollution to my knowledge - correct me if I am wrong. It is important that it does come from the sea as the sea contains many trace elements such as iodine which is lacking from the land and hence our agricultural produce.

While I do not use much salt, it is after all added to so many products such as cheese, butter, bread peanut butter etc. it is possible that total elimination may mean that we are getting insufficient iodine which was a major problem in Tasmania (goiters, thyroid problems) before iodine was added to table salt. I have no news or information on this, but I am curious, if anyone knows of any recent research.

I heard of some Australian salt coming from the inland lakes too. But I am interested too where the sea salt comes from but if you think of the amount of plastics in the ocean it must be in the salt too in micro sizes.

You can get iodine from sea vegetables or seaweed, but again needs to be from a clean source. Most people are having health problems from too much fat which is in all dairy products. I have not heard of the Tassie problems do you have a link for that story?

I am reading an interesting book by Anthony william called Liver Rescue, fascinating reading about health. He mentioned the celery and some vegetables have enough salt. 

And if anyone actually wants pink salt, what's wrong with our own Murray River pink salt.
