I saw a QF A333 aircraft at YSSY with its strobe lights blinking once every 1.5 seconds. I thought that Airbus strobe lights blinks twice every 3 second. This is how to tell between an Airbus or Boeing aircraft from a distance. Boeing aircraft only blinks once, airbus twice, I think MD-11 blinks twice?
But I am curious with that QF A333? Is it because of the latest release A333?

The double flash from the strobe lights is because there are two seperate strobe lights mounted next to each other on the wingtip. They are timed to flash in sequence. On some airplanes, like the DC-10, A-330-200, A-340-200/300 and MD-11 the double wingtip strobe lights are standard equipment. They are, and have been offered as an option (B-747), on other airplanes, and a few airplanes, like the B-757, B-767, and B-777, the double strobe lights are not offered at all.
This double strobe light package could be optional equipment on the A-330-300. Single flash strobe lights are all that is required for large or heavy commerical airplanes built after 1980.
