Technology giant Apple's sales in Australia grew by more than $1 billion last year lifting its profits, as our commitment to its iPhone remains unshakable, but the amount of tax the multinational paid fell.

Apple’s accounts lodged with the corporate regulator on Friday show it had total sales of $9.08 billion in the year to September 29, 2018 - up 13 per cent from $8.04 billion in 2017.

The iPhone maker returned a gross profit of $900 million from those sales, up from $756 million a year earlier.

But its tax bill fell by $18.8 million to $164 million.
