TGW (Tiger Airways) 2716 not listed in FlightAware data.

I was trying to monitor the flight of TGW2716 from Singapore Changi Airport to Perth International Airport on 11 Aug 2012 but noticed that the plane had left the Changi Airport at about 3.50pm. When I key in TGW2716, I keep receiving tracking information that TGW2716 is still at the airport which it arrived the day before and the day of the tracking keeps indicating Friday 10 Aug 2012 though the current date and time is shown at the top of the page.

Is there something wrong with the data?

For this flight we only receive information from ATC in Australia, the operator does not cooperate. So we don’t have any flight information until the flight enters the Australian FIR.
