For many years, the study "For the love or money" has been the best study of Australia's customer loyalty and loyalty programs. The 2022 edition is now released. You need to pay for the study itself, but the executive summary is free and accessible here.
It is worth a read if you are a retailer thinking about a loyalty program.
About 88% of Australians enrolled in at least one loyalty program. The average is 4.3.
About 46% consider themselves active, which is up on last year. That is a lot of people, about 40% of Australia active.
Have a read. I am confident you will get a few thoughts.
