Hi Stefan,
The Sydney Airport
website is where to look next time. For tomorrow, first light is 5:52am and last light is 5:57pm.
The first few flights are international arrivals: QF2,6,320 and SQ221 etc. The last flights leave from 9-10pm, like the Thais, Malaysians, Cathays. The website has full details.
Hope this helps.
