The two singing sisters known as the Veronicas have come third and fourth on FHM magazine's annual sexiest women in the world list, ahead of Miranda Kerr and Jennifer Hawkins.
About 230,000 Australian men voted to rank the top 100 women.
Jess Origliasso, who has recently been in the spotlight for her diminishing frame and speculation about her relationship with MTV host Ruby Rose, led the Aussie contingent on the list by taking third place.
Her sister Lisa Origliasso, who this week announced her engagement to former Australian Idol star and pin up Dean Geyer, was fourth.
US actor Jessica Alba won the top spot, while compatriot actor Megan Fox was second.
Aussie model Miranda Kerr took fifth place and former Miss Universe Jennifer Hawkins was sixth.
Aussies dominated the list, making up nearly one-third of the total with 29 representatives.
Singer Natalie Imbruglia was eighth and Lara Bingle rounded out the top ten.
Other Australian beauties to make the cut were 43-year-old newsreader Sandra Sully (62), middle distance runner Tamsyn Lewis (22) and Natalie Bassingthwaite (23).
FHM editor Ben Smithurst said it was no surprise there were so many Australians on the list.
"This is a reaffirmation that Australia is home to the world's sexiest ladies," he said.
"Australian ladies are known across the world for their beauty, charm and intelligence."
The list will be published in FHM's June edition, which goes on sale on Monday, May 5.
