That quote from the BAsource website is horribly convoluted and potentially confusing. The flight number southbound (LHR-SIN-SYD) is the BA15, it then changes to the BA16 northbound (SYD-SIN-LHR), so either the flight number is wrong or the destination (Sydney) is wrong.
No other info other than I do know the aircraft is still on the ground in SIN, so the “source” got that bit right.
