First time poster, but long time lurker.
I found ~$218 return flights to Uluru (aka Ayers Rock) from Sydney between Jan to April 2019 on Jetstar via IWantThatFlight. Deal ends tomorrow though! (24/9/2018).
There is a good choice of dates all around the $218 mark. I think the weather would be nicest around March or April. Also flying in Jan makes use of the Australia Day public holiday (Yes I'm the sort of person that includes cost of annual leave into the cost of the holiday!)
Examples dates are…
23rd Jan to 1st Feb (Makes use of the Australia day Long weekend and save some leave!)
6th Feb to 12th Feb
3rd Mar to 8th Mar
4th Apr to 10th Apr (Good weather too ~26 Degrees)
p.s. I'm always scouting for good flight or cruise deals from Sydney for myself. When I stumble on something worth sharing I post them up on my blog www.gohereinstead.com It's nothing fancy, just a handy way to share deals I find with family and friends.
I have affiliate links in this site. It doesn't make the flight more expensive, but it does give me a bit more encouragement to search for deals!
