I can't give you an exact time between the two cities (I used Kingston - Jamaica) as the starting point and you would have to travel SW to get to Sydney (Australia) a distance of 9299.4 miles, 14965.9 kms or 8075.6 nautical miles, again there are too many variables to give an exact time of travel, but you would definitely have to take into account the 15 hours time difference between the two cities, whilst Tuesday in the early morning (approximately 5am in Sydney it would only be Monday about lunch-time in Kingston).
That will depend on where in the world you are travelling from and what methods of travel you are using.
