Online travel-booking company Expedia is buying Australia’s Holdings for A$703 million ($658 million U.S.), seeking to expand its presence in the Asia-Pacific region.

Wotif investors will get A$3.06 a share from Bellevue-based Expedia and a special dividend of 24 cents, the Brisbane-based company said in a regulatory filing. The offer is a 25 percent premium to Wotif’s last market close.

Travel websites have been seeking revenue through acquisitions as more people book trips online. Internet travel sales may reach $151.9 billion by 2016 from $107.4 billion in 2011, according to eMarketer.

Expedia CEO Dara Khosrowshahi said in a statement, “Wotif Group is well positioned in the Asia-Pacific region with a portfolio of leading travel brands.”
