Sometimes when trying to search for award availability with Qantas your dates don’t line up with any Classic Rewards available. You can use paid for services out there to contact you if availability comes up, but I’ve found a free way with Distill Web Monitor
Install Distill Web Monitor into Chrome
Login to Qantas with your account
Search for the dates you are not seeing any availability , its better to choose “One way” Search ( Just do 2 search for each left ) with “use points” Ticked
After taking you to the search results Click on Distill icon top right and choose Monitor Parts of the page
Click on the No Seats Part for the flight you want to monitor or select all of them if you want and choose Save Selections
Next choose Show Config
Increase the delay to 10 and click Save
Device if you want this to be less then 6 hours for free you will need to choose a local device ( and leave your computer on ) or purchase cloud credits
You choose the alert system , I choose email
You will then be emailed if there’s any changes
