Starting from a standstill = applying torque. Have a peek at your engine mounts (passenger side in particular - is Singapore LH or RH drive? Anyway, the one above the crank pulley) and look for wear/hydraulic fluid leaks. Check for excessive wear in suspension components, such as lower control arm ball joints, struts bearings, etc.
If the knock is loud, finding a dry, shiny polished metal joint with lots of play shouldn't be difficult.
