Royal Bank of Scotland foreign exchange strategist, Greg Gibbs, said the dollar had performed strongly since the release of the jobs data.
The currency was trading at $US0.8772 just before the release of the data at 11:30 AEDT.
"It is initiated by the strong employment report," Mr Gibbs said.
"(It was) a massive surprise to the market and it is performing accordingly."
Mr Gibbs said the jobs report had lifted market expectations of the Reserve Banklifting the overnight cash rate at its next board meeting on March 2.
The RBA surprised financial markets when it left the cash rate unchanged at its meeting on February 2.
Higher interest rates can support a currency as investors move funds to where they earn the highest returns.
Australia's key benchmark rate of 3.75 per cent compares to Japan's 0.1 per cent and zero to 0.25 per cent in the US.
"There is still some doubt on what they will do, but there is a school of thought now that they will go next month," Mr Gibbs said.
For the rest of the Asian session, Mr Gibbs forecasts thedollar to trade between $US0.8800 and $US0.8920.
