TL;DR: Yes.
The Northern Territory is huge, and spans a range of climates from sopping-wet tropical to bone-dry desert. The current floods (Dec 2015) are primarily around the Daly River/Waters region, several hundred kilometers south of Darwin, and both Darwin itself and the tourist hubs of Alice Springs and Uluru (Ayers Rock), over 1000 km to the south, are entirely unaffected. All three have direct flights from Sydney.
All that said, it's The Wet right now in NT, meaning the tropical bits get a lot of rain even when it's not outright flooding. Down at Uluru though, it's summer and thus very dry and hot.
