Actually due to Perth's geographical position in relation to that great big ocean to the west of us we have extremely clear days during summer. That means that the amount of measurable light we have in comparison to other capital cities is much greater. So although we might have the same sunset and sunrise time as a cities relatively close to our latitude we actually experience more sunlight in terms of brightness or intensity.

The insolation figures would disagree if we looked at total average irradiance for all three cities. I do believe that Perth has more days than any other Australian capital where over 100 000 lumens per meter squared are recorded for longer than 2 hours <--- this is considered to be a bright day.
