A man is due to face a Sydney court after allegedly kissing a toddler at a Darling Harbour aquarium.

Police said the 28-year-old Indian national allegedly walked up to the two-year-old’s pram on Sunday afternoon and kissed the child on the lips after a short interaction.

Police said he didn’t know the family, and the parents pushed the man away and reported him.

The man is due to face the Central Local Court on Monday.
