Economy Classic Flight Reward with a Qantas (QF) flight number require 30% less points for domestic flights for travel between 1 March 2023 - 30 June 2023.
Seems to exclude Jetstar flights, meaning that Qantas flights require less points than Jetstar flights if they both operate the same route.
Book before 22nd January.

Eligible Classic Flight Rewards are all available Qantas operated Economy Classic Flight Rewards with a ‘QF’ flight number across Australia/the Domestic network (including Norfolk Island). If your Trip includes multiple flight segments the discount will be applied to the whole Trip e.g. Melbourne to Cairns via Sydney will be eligible for the discount if all flight segments are eligible Economy Classic Flight Rewards. If you make any changes to the date and time of your Classic Flight Reward booking, in order to be eligible to retain the 30% discount, any flight in your updated booking must be within the specified travel dates of this promotion. If your Trip includes multiple cabins, for example, Adelaide to Melbourne in Business and Melbourne to Cairns in Economy, the discount will not apply to your booking. If a Trip includes a Transfer (domestic - same day) or a Transfer (international - a flight within 24 hours) on other partner airlines, that trip is not eligible for this offer.
