Thankyou for the suggestions.
The only useful Booster I have in the Rewards app is 2k bonus ER points for $100 spent at Woolworths, however I've just done a shop at Coles / am done for the week and also weary of the time required for the points to land and be transferred if I do a $100 shop at WW.
Also, I don't really watch sports either, so Kayo isn't of use to me - yep, I'm very "boring" - don't drink or watch sports not available on FTA TV
I guess the quickest option would be to just top-up 1k points for $56.
