Until 31 December 2019, you’ll automatically earn points on your linked Qantas Frequent Flyer account with following rides:
Weekdays, 9am – 5pm
UberX: Earn 1 Qantas Point per dollar spent
Uber Comfort & Uber Premier: Earn 2 Qantas Points per dollar spent
All other times
Uber Comfort & Uber Premier: Earn 1 Qantas Point per dollar spent
Just to put it into perspective, 1 Qantas point is worth 1c
Edit: 1.1c for domestic and 0.7c for international. Why do people persue such points? It will take forever to gather anything of value and eventually their value can drop
