The retailer officially announced Kerr is leaving after five years, to be substituted by 27-year-old Gomes, still a celebrity newcomer when it comes to the big world of ambassador life, reported Vogue Australia.
The swimwear and underwear model - who has graced the Sports llustrated pages many times - is well known in fashion circles but has yet to hit the heights of instant public recognition.
Half Portuguese and half Singaporean-Chinese, Gomes was born and raised in Perth.
"I'm really proud to be Australian and I'm proud to be half Asian. I love Asia, and I love how that it's a big part of the economy. I think it's fantastic that Australia is using more ethnic girls now, and so they should - we are a very multicultural country so I think we should embrace all beauties," Gomes said.
