Establishing a little individuality is a challenge faced by most twins.
But nature has already given Alicia and Jasmin Singerl a helping hand.
Gorgeously chubby and sunny-natured, the five-month-old girls already turn heads when their parents take them out.
But many do a double take when they realise Alicia is black while Jasmin is white.
Experts say the chance of twins being born with such different physical characteristics is about a million to one.
The Australian sisters, who were conceived naturally, were born in May and live with their parents in Burpengary, north of Brisbane.
Their mother, Natasha Knight, 35, is of mixed-race Jamaican-English heritage, while their father Michael Singerl, 34, is a white German.
