China's breathtaking appetite for all things Australian - iron ore, real estate and baby formula - has gone sky high.

Now Chinese people could soon be getting a taste for Australian air, if two Sydney entrepreneurs have their way.

John Dickinson and Theo Ruygrok have devised a way to bottle the air we breathe freely and are selling cans of pure Yarra Valley atmosphere for $18.80 each.

"We want to give people internationally a chance to taste what our beautiful air is like," Mr Dickinson said.
