Do not spend much per shop at Coles for the foreseeable future. Scan much smaller amounts (use self-checkouts perhaps) on the card (say low $30s) and then put the rest of your spend through WITHOUT FlyBuys card scanning. Perhaps miss a week of any scan at all.
This may end up taking 6 to 8 weeks before the spend amount drops back to more likeable limits.
The few points you lose on the non-scanning are a tiny amount of a low spend 10K 4-weeks $50 spend offer. Best return on investment going!
