Expectations are growing that Singapore Airlines (SIA) plans to re-enter the Australian domestic market by investing in Sir Richard Branson's low-cost carrier, Virgin Blue.
Analysts have tipped SIA to take at least a 25 per cent stake in Virgin Blue as it continued to look for an alternative partner in Australia since the collapse of Ansett Australia earlier this year.
Reports this month had suggested that the carrier was in the market to buy Ansett's domestic operations from the failed carrier's administrators, along with rival bids from Emirates Airways and Dragonair.
However, all three carriers have since denied any interest.
'The costs of starting a new domestic airline in Australia are prohibitive and it is doubtful that any operation could be profitable given the dominance now of Qantas and Virgin Blue in the market,' a regional aviation analyst said.
'As such, the easiest way for SIA to get back into the Australian market is through a tie-up with Virgin Blue.'
