What is the optimum way to complete Qantas Points Challenge to reclaim expired points?

What is the best way to earn 2,500 Qantas Frequent Flyer Points without signing up to any credit cards? It needs to be from two different sources to reclaim over 80,000 expired QFF Points!

Woolworths Everyday Reward Points to Qantas Points will be one very small source so just need one other that will give me bulk points for minimum $$ spent.

Go to qantaspoints.com and click on “earn points”; have a look around to see if there’s anything that takes your fancy. One popular option is to buy wine from Qantas Wine.
