We teach our guys not to ask for Visual Approaches in Aussie as the requirements are so different and much more complicated than at home (or any other part of the world), that it is just not worth it. (unless you have a lawyer on board to check the fine print in the Aussie regs
)
In NZ the requirements are that by day you must be able to proceed with a reasonable assurance of mantaining viz ref to the airfield, but at night must have the
white runway lights in sight. Simple really!
